Agilent 8591A | HP 8591A Used Spectrum Analyzer,9kHz to 1.8GHz 

Manufacturers: Agilent | HP
Description: The HP Agilent 8591A is a used Spectrum Analyzer that covers the range from 9 kHz to 1.8 GHz with a center frequency accuracy of 210 Hz at 1 GHz.
Other Info:
The Agilent HP 8591A used Spectrum Analyzer has over 100 functions and are controlled either from the front panel or over the optional HP-IB interface.Advanced marker functions measure: the 99% power bandwidth of a signal; the 3 dB points of a signal; frequency; amplitude; amplitude and frequency differences on a signal; and highest peaks on a signal. The Next Peak button moves the marker to the next highest signal, simplifying harmonic measurements. Other measurement functions on the 8591A include: percentage AM; signal-to-noise ratio; and the FFT. Store/recall up to nine complete front-panel states in battery-backed RAM.
