Tektronix spectrum analyzers extend analysis up to 20GHz


Electronics CEL

Tektronix Inc. announced it has expanded the RSA6000 series to include the RSA6120A spectrum analyzer, which extends all of the industry-leading capabilities of the RSA6000 Series out to 20GHz, allowing designers to apply the spectrum analyzer's market-leading capabilities throughout the entire Ku band.

With the RSA6000 series of spectrum analyzers, Tektronix also introduced swept DPX which is proving indispensable to designers in their discovery of previously unseen signal anomalies. Now designers can take advantage of the advanced capabilities of the RSA6000 series when developing and characterizing radar and electronic warfare systems and components that operate in the X (8-12GHz) and Ku (12-18GHz) bands. In these applications, designers can use the RSA6120A spectrum analyzer to set up automated measurements that allow them to understand the behavior of transmit waveforms, validate a transmitter’s design, and debug problems in a radar receiver.



The new RSA6120A spectrum analyzer also supports applications in spectrum management, particularly in intelligence, regulatory monitoring, and defense applications. The new spectrum analyzer extends the series’ signal discovery and triggering advantages up to 20GHz, allowing a clearer understanding of how digital signal processing (DSP) interacts with RF signals of interest. This feature can be used to understand the level of interoperability between radio systems used by different divisions or agencies, for example.


The RSA6120A provides dynamic range at Ku-band frequencies, featuring a spurious-free dynamic range of 75dB and a third order intercept of +19dB above 6 GHz. It also features channel flatness operation for all measurements due to a switched-filter preselector. Flatness across 100MHz, for instance, is specified at +/- 0.7dB RMS and  +/- 1.5° RMS. Allowing for confident measurements of signals that are free from distortion, this level of performance is possible because of the RSA6120A spectrum analyzer’s enhanced vector calibration procedure.


In addition, the RSA6120A provides radar designers with powerful signal analysis tools, including impulse response, and 26 other automated pulse parameter measurements, statistical measurement and waveform replay with acquisition history.
