The RSA5126B from Tektronix is a Real-Time Spectrum Analyzer that operates from 1 Hz to 26.5 GHz. It has a real-time acquisition bandwidth of 25/40/85/125/165 MHz and a minimum event duration of 2.7 µs (@ 165 MHz BW) for 100% POI at 100% amplitude. This RTSA uses the patented DPX® spectrum processing engine to provide live analysis of transient events to spectrum analyzers. It can perform up to 3,125,000 frequency transforms per second, which results in an event duration of 0.434 µs in length in the frequency domain. It provides standard analysis for measuring channel power, ACLR, CCDF, OBW/EBW, spur search, EMI detectors, amplitude, frequency, phase vs. time, DPX spectrum, and spectrograms.
The RSA5126B has a real-time SFDR of 80 dB over the entire acquisition bandwidth and has a phase noise of -134 dBc/Hz @ 10 MHz offset. It helps users to easily discover design issues that other signal analyzers may miss. The DPX® spectrum display offers an intuitive live color view of signal transients changing over time in the frequency domain or instantly displaying a fault when it occurs. Once a problem is discovered with DPX®, the RTSA can be set to trigger on the event, capture a contiguous time record of changing RF events, and perform time-correlated analysis in all domains.
The RSA5126B is available in an enclosure that measures 282 x 473 x 531 mm with various interfaces. It requires an AC supply and consumes less than 400 W of power. This RTSA is suitable for analyzing wideband radar and pulsed RF signals, frequency agile communications, broadband satellite, and microwave backhaul links, education, Long Term Evolution (LTE), cellular, 5G NR cellular base station or user equipment transmitter test, and EMC/EMI pre-compliance and troubleshooting.
