3GHz Spectrum Analyzer

Featuring high performance, uncompromised design, and remote monitoring software, the GSP-830 3GHz Spectrum Analyzer is the latest evolution from GWInstek. The GSP-830 is one of the most advanced Spectrum Analyzer GWInstek has produced to date. The GSP-830 has an exceptional noise floor of -152dBm/Hz; combined with the optional GAP-802 preamplifier, the noise floor can reach a remarkable -172dBm/Hz. With a low noise floor, the GSP-830 is more than capable of finding limits; Trace Detection, combined with an easy-to-use interface, makes the GSP-830 an ideal solution for spectrum analysis. Using the Auto Sequence mode, advanced users can define their own macros in 10 Sequence sets. Repeat or Single run mode can be used to streamline repetitive tasks. PC connection is effortless and versatile supporting USB host/device, RS232C, VGA and GPIB (optional) for remote monitoring, control and analysis.
