Mid-range real-time spectrum analyzer offer enhanced performance

January 24, 2013 // By Jean-Pierre Joosting
Tektronix has announced its lowest cost real-time spectrum analyzer for mid-range performance, featuring advanced signal discovery and triggering capabilities. Included in the expansion of the RSA5000 real-time spectrum analyzer series are 26.5 GHz and 15 GHz models along with the recently-announced 110 MHz bandwidth option that is now available on all the company's real-time spectrum analyzers.

Available for the first time in a mid-range spectrum analyzer, the 110 MHz bandwidth option is especially important because many of today's wireless communications standards require engineers to see a wider frequency range. The wider bandwidth also enables uninterrupted signal monitoring or surveillance of frequency bands of interest.

The DPX spectrum display used in the RSA5000 offers an intuitive live color view of signal transients as they change over time in the frequency domain. This live display of transients is impossible with other signal analyzers. A number of advanced DPX features including swept DPX, gap-free DPX spectrograms, and DPX zero span with real-time amplitude, frequency, or phase make it easy to find troublesome signals under a variety of conditions.

The RSA5000 provides a comprehensive set of triggers essential for troubleshooting modern digitally implemented RF systems. These include time-qualified power, runt, density, frequency, and frequency mask triggers. Also included are a number of DPX triggers including the DPX density trigger that works on the measured frequency of occurrence and "trigger on this" that allows the user to point at the signal of interest on the DPX display.

The RSA5000 series accelerates troubleshooting and analysis by pinpointing the root cause of problems in multiple domains. Engineers can analyze captured data across domains at any time using correlated markers. Time-correlated measurements can be made across frequency, phase, amplitude, and modulation domains. This is ideal for signal analysis that includes frequency hopping, pulse characteristics, modulation switching, settling time, bandwidth changes, and intermittent signals.

For deep troubleshooting and analysis, RSA5000 data captures can be used with SignalVu-PC software for offline analysis helping to free up test resources. Like the RSA5000, SignalVu-PC offers extensive vector signal analysis functionality spanning spectrum, spectrogram, and RF measurements including analog modulation analysis, adjacent channel power, CCDF, occupied bandwidth plus amplitude, frequency and phase versus time. Options for more advanced analysis functions are also available including modulation, pulse, settling time, audio
