These presets can be transferred to and from other units (same model) using the USB port. An Ethernet port allows for easy download of screenshots and the Error Log.


See and Solve with Tektronix displays

The “See and Solve” displays in Tektronix video monitors simplify video monitoring tasks such as calibration, error detection, and content correction allowing the user to detect errors at a glance and troubleshoot them efficiently.

Tektronix displays offer the sharpest CRT-like trace quality for clear waveform monitoring with the look and feel of an analog display. The familiar video waveform display can show SD/HD/3G-SDI signals in RGB, YPbPr, YRGB, or pseudo composite. Signal components can be displayed in either Parade or Overlay mode. Cursors within the waveform display allow precise measurement of Voltage and Time to be made. The vector display offers user-selectable graticules, color targets (75% or 100%), and color axis.

With several sweep rates and easy control of vertical gain and horizontal magnification, you can efficiently monitor and measure video waveform parameters.

Specialized displays provide summarized, yet comprehensive reports of alarms, session, and status of content. Powerful displays such as Video Status show a condensed view of error statistics, signal format, presence of ancillary data, and more. These Tektronix-exclusive displays simplify monitoring tasks by providing important content information at a glance.

Errors in the displays can automatically be logged in the Error Log and provided as a report.

Advanced physical layer measurements in a portable platform

The WFM2300 portable platform offers the physical-layer signal measurements suitable for Installation and Maintenance applications. When equipped with Option 3G, the WFM2300 can perform 3G-SDI eye pattern display, jitter measurements, and cable length measurements on the SDI A input.

The WFM2300 provides unique capabilities such as reporting jitter levels above 1 UI and providing various jitter filters from 10 Hz to 100 kHz for SD/⁠HD/3G-SDI signals. An easy-to-interpret gauge provides direct readout for jitter measurements. Users can configure timing jitter, alignment jitter or other jitter filter to effectively isolate the sources of jitter.

The SDI Status display summarizes key signal parameters such as signal strength, cable loss, and estimated cable length measurements. With FlexVu™, users can display the jitter value and cable parameter measurements to help quickly diagnose and resolve problems related to SDI timing jitter or cable attenuation.


3G-SDI monitoring.

The infinite persistence mode of the waveform monitor can also be used to more easily view the eye opening of the physical-layer signal. In addition, the WFM2300 can also perform automated eye amplitude, automated rise/fall time, automated overshoot measurement, and provide jitter waveform display to view jitter related to line and field rates. All of these capabilities help engineers in the field to detect and diagnose signal quality problems quickly and efficiently.

Wide variety of interface support

In modern broadcast facilities, there are a wide variety of video and audio signal formats that require multiple tools to monitor the signal. The WFM2300 is able to support SD/HD-SDI, 3G-SDI (Option 3G), ASI (Option ASI), AES/EBU digital audio, composite black burst or tri-level sync reference signals, optical SDI (Option SFP), and HDMI (Option SFP-HDMI), which provides a one-instrument solution for a wide variety of formats.

The SDI A input provides monitoring of Eye and Jitter measurements on SD/HD-SDI and 3G-SDI (Option 3G) video signals and provides Eye measurement on ASI (Option ASI) video signals. For a Dual Link SDI signal, both the SDI A and MULTI IN inputs are used.

The MULTI IN input also supports SDI, ASI, AES/EBU and LTC signals so that the user can easily determine the type of signal present on a cable.

The AES OUT and SDI OUT connectors are test signal outputs that can be configured as loop through outputs. The individual outputs for Audio and Video in conjunction with the SDI A and MULTI IN inputs allow the user to evaluate the variety of Audio/Video equipment that may require the audio/video signal with separate path.


Variety of interface support (Eye display of SDI input, Audio display of AES/EBU input, Waveform display of external reference input, SFP Module Status display of optical input).

The REF IN connector is used for receiving the analog composite or tri-level sync signal to measure the timing or check the sync status between sync signal and SDI signals. It is also used as a Genlock signal source for the generator function. In addition, the analog reference signal connected to this connector can be displayed as a waveform to quickly check the quality of the sync signal.

The optical SDI interface (Option SFP) is supported with a transceiver SFP module. The transceiver module provides both an input and output that can be used simultaneously. The output can be configured as loop output or as a test signal output. The HDMI interface (Option SFP-HDMI) is supported with an HDMI type-D receiver SFP module. The SFP status display shows the module model name, mode, temperature and other status of the SFP module.

The STRESS LOOP connectors are a bi-directional passive signal path that can be used with a SDI test signal generated by the WFM2300 to test a signal path, or to add an additional cable length and interfering signal to a signal path to provide simple margin testing.

Quickly diagnose and isolate an installation issue

In a broadcasting facility, it is important to ensure the health of the signal so that the clock and data are decoded correctly and the health of the SDI system is maintained. CRC detection within the SDI signal can be used to count the CRC errors if present in the system. The measurement, however, may take minutes or hours to ensure that the signal is error free.

The cable stress/margin loop adds an additional 20 meters of Belden 1694A cable and an interfering signal to the signal path. The use of the stress/margin loop with CRC detection simplifies how to determine the cable margin of a system so that the user can quickly ensure they do not reach the “digital cliff” where the transmission error rate significantly increases.

Alarms, quality statistics, and logging – thorough and fast content verification

This instrument offers a variety of displays designed to show status at a glance, in addition to the status bar continually displayed at the bottom of the screen.

A comprehensive overview of the video content status is presented in the Video Session display. Offering a time-based summary of information, this screen is ideal for presenting evidence of compliance after content screening. Information on input format and session time is presented, along with statistics on Error Detection and Handling (EDH) / Cyclic Redundancy Check (CRC) and gamut errors.

The Alarm Status display provides continuous information on the state of each condition currently being monitored by the instrument.

To support unattended monitoring and QC applications, as well as provide documentation for service-level agreements, these instruments maintain an error log of 10,000 events, which facilitates the detection and correction of problems. Log entries are recorded with date, time of day, and time code (VITC, LTC, ANC). The error log can be downloaded to a USB flash drive or through a network connection to .TXT or .HTM formats for easy record keeping and processing on spreadsheets or database software.

Picture display with Safe Area Graticule.

You can select bright-up conditions that show the location of RGB or composite gamut errors on the Picture display. The Line Select mode shows the location of the line currently selected within the Picture display.

Users can choose from several Safe Action and Safe Title graticules on the Picture display which help editors and operators easily identify incorrectly positioned video content such as graphics, titles, or logos.

Graticule choices include the Safe Action and Safe Title graticules defined in SMPTE RP218, ITU, and ARIB standards, plus two sets of completely flexible, user-definable graticules. These graticules facilitate editing tasks and reduce the need for format conversions.

Patented Tektronix gamut displays – efficiently detect and allow correction of gamut problems

The Tektronix-patented Diamond, Split Diamond, and Arrowhead displays simplify the process of verifying gamut compliance and are ideal for colorists, editors, and operators to visualize whether the content is RGB or Composite Gamut compliant with a single glance. Plus, they are designed to help isolate the Out-of-Gamut component just as easily.

For SDI component content that is destined for broadcast in composite systems, the unique Tektronix Arrowhead display can be used to monitor Composite Gamut compliance without the need for a separate encoder. Within this display, a separate upper and lower luma-only gamut limit can be applied.

Each of these displays offers user-selectable gamut thresholds so that operators can set monitoring limits appropriate to their specific operation and include a preset for EBU-R103. You can also select bright-up conditions to see the location of gamut errors on the Picture display. In addition, gamut monitoring is fully integrated with the powerful alarm logging and reporting capabilities of the instrument.

Quad Tile display – flexible monitoring configuration customized to suit your application

Tektronix offers multiple display options to suit a variety of applications that can be customized to the user’s needs. The Quad Tile display provides flexibility to increase your productivity. The user can configure four different displays within the one instrument. A maximum of two traces can be displayed, along with picture, status, and audio bars to create flexible monitoring configurations that can be saved as presets for quick and easy recall. For instance, a waveform parade, vector, picture, and audio bar display can be configured to monitor the audio and video signal simultaneously within the Quad Tile display.

Unlike instruments with predetermined view combinations, Quad Tile lets you create a Quad Tile display tailored to your specific needs and work practices. Each tile can be configured to enable easy signal analysis such as multiple alarm and status screens, different Safe Area Graticules and cursors on each tile, and more.


Quad Tile display allows for displays to be viewed simultaneously.

Digital audio and video monitoring in one instrument

High-quality digital filtering and oversampling by the monitor ensures precise, reliable, and repeatable audio measurements. The instrument provides 16-channel embedded digital audio monitoring with Audio Bars, Lissajous Displays, Surround Display 2, and a headphone port for easy compliance verification of digital audio without the need for an additional piece of equipment. Flexible mapping of the embedded audio inputs to the audio bar displays allows for a variety of audio mixes to be supported from multiple stereo signals to surround and stereo support.

The Surround Sound 2 display provides intuitive graphical representation of channel interaction in a surround sound system. The Bars display provides indication for faults, audio levels, and provides indication of the presence of a Dolby format. The flexible Lissajous display allows the selection of any two audio channels.


Audio display with Surround Sound monitoring.

Loudness monitoring in a portable platform allows the user to verify on location that the audio levels are within the loudness measurement limits. A Loudness meter is available within the Audio display that provides Short and Infinite Loudness measurements. Within the Configuration menu, there are simple Loudness presets for the various standards such as ATSC A/85, EBU R128, and ARIB TR-B32.

Specialized audio displays provide deeper inspection of the signal and make the instrument a comprehensive compact waveform and audio monitor. The audio session displays summarize levels, faults, and number of active bits for each channel. These instruments also feature Audio Control Packet Data and Channel Status displays.

With Option DBE, the Dolby Status display gives an in-depth view of discrete audio or VANC metadata and Dolby E Guard Band timing and synchronization. User-configurable thresholds for the Dolby E Guard Band timing measurement are available as well as triggering alarms based on their specific guard band parameters. The peak level data in the Dolby metadata is also displayed as a bar graph for checking the presence of the signal.

In addition, Option DBE supports Dolby E audio generation, which provides easy access to Dolby E audio reference and test signals within modern broadcast facilities. These signals include test tones at different levels (–⁠18 dB, –20 dB and Multitone) with frame rates compatible with the respective video signals. The Dolby E stream can be output from the SDI output as embedded audio or from AES/EBU output.

The user can set the Dolby E audio frame start locations (Early, Ideal, Late, or Custom) to test the error handling ability of the signal processing equipment in the signal path. Dolby E metadata is also inserted in the test stream, which can test the performance of signal processing equipment downstream. The user can configure each of the three D’s of Dolby (dialnorm, dynamic range and downmix parameters). The Dolby E program configurations of 8x1 mono, 4x2 stereo, surround 5.1, 5.1+2 and 7.1 audio are supported.


Optional Dolby E signal generation and metadata monitoring.

Facility timing made easy

Audio/Video synchronization is an important challenge in the processing of video materials. With Option AVDP, the A/V delay is displayed on a graphical bar indicator. The measurement readout gives facility engineers the necessary tools to ensure system integrity and facilitate A/V delay compliance. This feature provides out-of-service measurement of A/V delay for digital audio and video formats and requires the use of the internally generated test signal to create the flash pop sequence. Alternatively, a Tektronix SPG8000 with Option SDI or a TG700/TG8000 with an SDI7 module can be used to generate the test signal.

When using the embedded test signal generator, a propagation delay measurement can be made in a closed loop by measuring the time between the video signals leaving and returning to the instrument. This propagation delay measurement makes it easy for the facility engineer to align the timing of the multiple incoming videos, check the delay of a CODEC system and/or a video signal path, including satellite feed.

The Tektronix-patented SMPTE RP168 compliant Timing display makes facility timing easy through a simple graphical representation which shows the relative timing of the input signal and the reference signal (or a saved offset reference) on an X-Y axis.

The Lightning display shows luma and chroma amplitudes and helps users verify interchannel component timing using a color-bar signal. The Tektronix-patented Bowtie display complements the timing measurement capability of the Lightning display. Using a special Bowtie test signal in component format, this display helps make precise, accurate measurements of interchannel amplitude and timing.


Timing, Lightning, and A/V Delay/Propagation Delay displays simplify timing tasks.

Troubleshooting signal paths

A test signal can be generated from the SDI output that produces a variety of test signals with the ability to Genlock the test signal output to the External Reference Input. Audio test tones and/or a Dolby E test signal stream (Option DBE) can be generated at the AES output or embedded in the SDI test signal output.

The user can change the test signal patterns, video format, whether the test signal is moving or static, audio test tone, and audio level. The moving test signal allows the user to easily identify whether the test signal is active “live” or still and helps determine problems within the signal path that are caused by equipment freezing on the last frame. This can be useful for troubleshooting a signal path or piece of equipment without the need to carry an additional generator.

Superior data analysis capabilities for operators and engineers

The ANC Data Inspector provides an industry-leading solution to help broadcasters easily and accurately ensure that all required VANC data is present and correctly configured through an intuitive ANC data display.

In contrast to other solutions, the ANC Data Inspector enables operators to quickly and easily ensure that the VANC data is present and free of errors. When errors are detected, engineers are quickly guided to a more detailed view of the data packet content for further analysis.


ANC Data Inspector provides detailed content analysis.

Closed Caption (CEA708/608) and individual Teletext subtitles can be simultaneously decoded and displayed within the Picture display. Teletext subtitle pages can be decoded in either WST or OP47 format.

The Auxiliary Data Status display provides summary information on Active Format Description (AFD) per SMPTE 2016, Video Index Aspect Ratio, Wide Screen Signaling (WSS), V-Chip, TSID, CGMS-A, Broadcast Flag, CEA708/608 Closed Caption, Teletext, and Timecode information.


Monitoring of Ancillary data (Closed Caption, Time Code, and AFD) using Aux Data Status.

Today there is a wide array of metadata that provides information to a variety of equipment through the processing chain. Monitoring of this metadata is critical to ensure that the processing equipment correctly handles the signal. For instance, correct format of the AFD ensures that the aspect ratio on the display is correctly formatted and the automated AFD graticule is available for the Picture display, along with the binary data and text description, for easy monitoring.

The Datalist display provides detailed information on the actual data values in HD/SD-SDI and 3G-SDI (with Option 3G) input signals. Users can easily use this display to locate protocol errors in the input signals.


Datalist display provides detailed pixel-by-pixel information.

The right side of the display shows the data values in hexadecimal, decimal, or binary format and uses the following color coding for easy identification of data types and errors:

  • Green – Active video data
  • Blue – Data in horizontal or vertical blanking intervals
  • White – EAV, SAV, and other reserved words
  • Yellow – Data outside nominally allowed values
  • Red – Data with illegal values

The left side of display shows uninterpolated digital values plotted against sample numbers as a digital waveform. You can configure this unique display in either Video mode or Data mode.

In Video mode, the display shows the Y, Cb, Cr values aligned temporally, but offset vertically. Like the waveform display, you can configure the display to show 1, 2, or all 3 components.

SDI and ASI monitoring in one instrument

Engineers within a broadcast facility need measurement equipment to support both SDI (Serial Digital Interface) and ASI (Asynchronous Serial Interface) in a single instrument, which allows them to troubleshoot a variety of issues all within one portable device.

With Option ASI, the instrument offers automatic format detection, which allows the user to quickly determine the format of the SDI or ASI input signal on either the SDI A input or MULTI IN input.

When an ASI signal is detected, the instrument can display the MPEG TS PID tree with TS bit rate, TS packet size (188/204 byte per packet), ASI polarity, as well as the continuity counter error described in ETSI TR 101 290. This helps engineers identify the structure of the transport stream and determine potential issues with the signal. Sync byte errors and continuity counter errors are logged in the error report to help users investigate intermittent issues. The instrument also performs Eye pattern measurement on the ASI signal to ensure signal quality in the physical layer.


ASI monitoring (MPEG2 PID Tree display, Error Log status display, Eye pattern measurement display, SDI/ASI Status display) is available with Option ASI.

Supported formats

This instrument accepts a wide variety of input signal formats and external references. It will automatically detect the signal format and establish the appropriate settings for the various displays.
