Spectrum Monitoring and Interference hunting
The migration to mobile communications is creating unprecedented pressure for more spectrum capacity in a complex and crowded signal environment. Tek’s Real-Time Spectrum Analyzers help you discover and examine sources of interference quickly so you can locate and identify unwanted activity. You can ensure your signal integrity and adherence to compliance standards using the RSA306B, RSA500, or RSA600 for real-time spectrum insights.
- The RSA306B spectrum analyzer's proprietary DPX technology enables precise, real-time measurements packaged in a portable, rugged form factor and easy-to-use software interface.
- The RSA306B spectrum analyzer covers up to 6.2 GHz, with 40 MHz bandwidth capture
Reduce manufacturing costs and test time with better test flexibility
The USB RSA’s are a great choice for manufacturers looking for greater throughput and product quality, all while controlling testing costs. The RSA 306B, 500, and 600 units offer support for major Internet of Things (IoT) standards in SignalVu-PC software, come with a complete offering of drivers and code examples, and include testing support for IoT technologies such as WiFi and the new Bluetooth 5.0.
Maximize your student’s learning
With our full featured and affordable Real-time Spectrum Analyzers, your students can capture results of experiments, perform analysis, and generate lab reports on their laptops, saving time and optimizing learning opportunities. It’s compact and portable size makes it easy to conduct experiments away from the lab in real world environments.
EMI/EMC pre-compliance Testing
Save cost and precious time by performing pre-compliance testing in your lab with our Real-Time Spectrum Analyzers. You can use peak detection with a free version of SignalVu-PC. You also get more accurate results with quasi-peak and average detection by purchasing the additional option EMCVu. Learn more about EMI/EMC pre-compliance testing at our application page.

SignalVu-PC software brings benchtop and field features to the RSA306B
RSA306B operates with SignalVu-PC, a powerful program that is the basis of Tektronix performance signal analyzers. The software controls the spectrum analyzer acquisition and updates measurement displays continuously.
The base version ships free with the product; add options to configure the software for your application.
- Free base version has 17 signal analysis and real-time spectrum analysis measurements
- Paid add-on options for more than 15 advanced measurements including WLAN testing, P25 compliance testing, pulse analysis, modulation analysis and more
Smart antenna for interference hunting
When combined with a Tektronix USB spectrum analyzer, the Alaris DF-A0047 direction finding antenna, offered by Tektronix, makes interference hunting easy. Lines of bearing are automatically transmitted from the antenna to SignalVu-PC Map software, enabling fast triangulation on interference sources.
- Multiple antennas and a user-selectable preamplifier cover a broad range of interference frequencies and levels
- Integrated compass transmits angle information to SignalVu-PC for automatic creation of lines of bearing on the map
