Real Portable · Real Performance · Real Affordable

The SRA-Series is Saluki’s latest release of handheld real-time spectrum analyzers with frequencies up to 40GHz. Building on continuous innovation and SWaP-C design principle, the SRA-Series offers an unmatched combination of size, performance and cost. RF measurements and analysis from 9kHz to 40 GHz is now carried out in a robust instrument with 10.1-inch full-touch screen and weight only 1.4kg.

The SRA-Series real-time spectrum analyzer offers 100 MHz analysis bandwidth, ultra-fast speed of 900 GHz/s, delivering standard spectrum sweep (SWP), IQ streaming (IQS), zero span (DET) and real-time analysis (RTA) working mode. And equipped with preamplifier and 19-segment preselector, achieving good dynamic range and phase noise level. It can provide customers with spectrum analyzer, spectrum monitoring, interference finding, RF test and measurement functions.
