Handheld Spectrum and Vector Network Analyzer Heads to the Field
This article appeared in Microwaves & RF and has been published here with permission.
Siglent Technologies recently introduced the SHA850A series, its first handheld spectrum and vector network analyzer. Highly integrated and specifically designed for field operation, the lightweight and portable device performs accurate measurements and offers flexible analysis capabilities. Able to handle advanced characterization or signal capture applications in harsh working environments, it provides professional accuracy with flexible analysis capabilities.
In spectrum-analyzer mode, it can measure up to 7.5 GHz. The DANL is as low as –165 dBm, which can effectively identify small signal levels. The single-sideband phase noise is ≤104 dBc/Hz @ 1 GHz with a 10-kHz offset; an independent full-frequency source and a 25 dB preamplifier is standard.
The SHA850A series’ measurable frequency range in vector-network-analyzer mode and cable- and antenna-measurement mode spans 100 kHz to 7.5 GHz, with a dynamic range as high as 114 dB. This critical range suits the SHA850A series for applications such as measuring the passband and out-of-band rejection performance of filters at the same time, as well as measuring narrowband devices with high rejection.
