The Keysight / Agilent / HP 8590B offers basic RF and microwave measurement performance at a low cost. The HP 8590B has a frequency range of 9 kHz to 1.8 GHz, a 50- or optional 75-ohm input, and a weight of only 13.6 kg (30 pounds). Amplitude range is a wide -115 to +30 dBm. If ac power is not available, this spectrum analyzer can be operated using the HP 85901A portable ac power source.

You can change the test capabilities of these spectrum analyzers to fit specific measurement needs. An optional memory card reader enables you to load specific measurement personalities for cable television, electromagnetic compatibility, or digital radio applications. Complete measurement routines and test limits are available at keystroke. An optional built-in tracking generator provides the HP 8590B RF analyzer with a synchronously swept signal source for stimulus-response measurements. Operating these analyzers requires only minimal training.

Numerous features make it easier to control your measurements and to analyze the results. Both portable spectrum analyzers have built-in, automatic calibration to ensure measurement consistency. Frequency panning lets you quickly reposition signals without repeated sweeps. The internal memory allows 50 traces to be stored, and 24 more can be stored on a RAM card with addition of the optional memory-card reader. Time-and-date stamping come standard. Direct output to printer or plotter are available with either the HP-IB or RS-232 interface option.
