Industry-leading Probe Performance

Probes should not be overlooked as a key element in the measurement signal path. When you buy a 3 Series MDO you get the industry’s best probes free. Featuring industry-best loading of 3.9 pF to your oscilloscope, the TPP Series probes will be your go-to probe for everyday use.

Highlights

  • TPP Series probes included standard. One per analog channel.
  • Industry-best capacitive probe loading of 3.9 pF
  • 250 MHz, 500 MHz or 1 GHz probe bandwidth depending on instrument bandwidth

Low-level signal measurement accuracy improved by as much as 40%

When you are measuring low level signals, it is critical to have a low instrument noise floor for better measurement accuracy. New front-end used in 3 series MDO can help you improve your noise measurements by as much as 40%. When you are evaluating an oscilloscope, be sure to carefully check the random noise specifications of the oscilloscope. Not all oscilloscopes are created equal, and not all oscilloscope manufacturers test and publish their random noise specifications.

  • 1 GHz maximum frequency comes standard in every instrument, 3 GHz is optional
  • Industry's only true integrated spectrum analyzer hardware in its class
  • Ultra-wide capture bandwidth up to 3 GHz

Capable. Upgradeable.

Get all the debug tools you need right away or add them when you need them.

  • Bandwidth up to 1 GHz
  • Digital channels: MSO option adds 16 digital channels
  • Spectrum Analyzer up to 3 GHz
  • DVM/Freq Counter (free with registration)
  • Arbitrary/Function Generator
  • Advanced Analysis
    • Serial bus decoding and triggering
    • Automated Power Measurements

July 2021 firmware release enables new features

Vertical grid readouts on-screen

Enables rapid visual inspection and analysis of amplitude measurements.

  • Time domain view has been enabled with vertical graticule labels
  • Enables rapid visual inspection and analysis of amplitude measurements
  • Supports all analog sources

Enhanced cursor measurement

Provides a quick at-a-glance view of the frequency domain or number of periods per second for a given waveform, offering greater flexibility when troubleshooting.

  • See the frequency readout in cursor as 1/(Δt)
  • Supports all cursor types, all sources and bus and digital channels

Export Ink saver screen captures with e*Scope

Now you can invert your display and take screen grabs without having to save files, all while using e*Scope software from a remote web browser. Enjoy cost savings on printer ink and save time when adding waveform captures to reports.

  • Set the mode Inverted/Normal from UI in user preference
  • Preview button in Print will be always visible which will give the actual print/screen capture.
