The portfolio of high-performance cost-effective analysis tools has been given a lift with the latest and updated Tektronix USB real-time spectrum analyser, which offers improved functionality to electronics design engineers working with RF signals, and is ideal for field, factory or academic use. The RSA306B adds new functionality and further benefits. It replaces the RSA306.

The analyser’s wide frequency range from 9kHz to 6.2GHz covers the bandwidth from conducted EMI to the latest wireless LAN standard, allowing analysers to view data over the entire working spectrum.

Key features of the tool include: a minimum signal event duration of 100μs for 100% probability of intercept; and a real-time spectrum/spectrogram display over a 40MHz bandwidth, which minimises the time spent on transient discovery and interference hunting, allowing engineers an immediate insight into the toughest problems.

Enhanced measurement options include mapping, modulation analysis, standards support and pulse measurements.

Other specifications include a +20 to –160dBm measurement range and spurious-free dynamic range (SFDR) of 60dBc (typical).

Ready to connect to a PC via its USB3.0 interface, the analyser operates with the SignalVu-PC software. This provides 17 spectrum and signal analysis measurements as standard and is the same analysis software as used on Tektronix's high-performance signal analysers and oscilloscopes, providing users with measurement confidence and high flexibility while problem solving.

Direct control of the analyser is provided via the API, which means that users can transfer data to other programs for further analysis; for example, also included is a MATLAB driver, which has support for Instrument Control Toolbox.

Additionally, streaming capture to disk enables gapless recording of long-duration events to aid in troubleshooting and interference hunting.

The instrument performs a wide range of functions including radio emissions testing using quick, complete and time-saving EMI checks for pre-compliance and diagnostics. Troubleshooting can also be investigated using powerful debug tools such as DPX and Domain correlation.

Bluetooth and WLAN testing and troubleshooting are provided using module support that speeds up testing for popular IoT wireless standards. Regulatory monitoring capability is also provided by the industry’s best open signal database, so users can see signal compliance at a glance.

The portable and lightweight device, measuring only 30.5 x 190.5 x 127mm and weighing only 560g, is compliant with Mil-STD-28800 Class 2 environmental, shock and vibration specifications, making it ideal for use in harsh conditions in problem areas, whether inside or outside and in either hot or cold environments.
