Option 01 is the Calibrated Internal Preselection. Filtering of input to first mixer for each frequency band, Option 02 is the Digital Storage. With Save A, maximum hold, B minus Save A, display averaging, and storage bypass, and Option 03 is the Frequency Stabilization 100Hz Resolution. Provides first local oscillator stabilization by phase locking the oscillator to an internal reference.

WE WILL RE-CALIBRATED THE ANALYZER AND PROVIDE A NIST TRACEABLE CALIBRATION CERTIFICATE BEFORE WE SHIP IT OUT.

The 492 Portable Spectrum Analyzer is a high performance, rugged, microprocessor aided instrument of compact size and offers automatic modes. Three-knob operation provides use as simple as 1, 2, 3 through microprocessor coupled functions such as resolution bandwidth, video bandwidth, sweep time, frequency span, RF attenuation, and reference level. This portable spectrum analyzer covers from 50kHz to 21GHz (to 220GHz with optional waveguide mixers, sold separately). Offers fully calibrated amplitude and frequency along with CRT readout of all important parameters for operator convenience and quick setups. Amplitude comparison in 0.25 dB steps. Dynamic range of 80 dB. The instrument has a resolution bandwidth of 1MHz to 1kHz in decade steps, plus an autoposition. Resolution is within 20% of selected bandwidth. The waveguides and diplexer are in another ebay sale.

I HAVE DIFFERENT HP - AGILENT SPECTRUM ANALYZERS ON DIFFERENT SALES. TAKE A LOOK AND YOU MAY FIND SOMETHING ELSE YOU MAY NEED!

It was just calibrated. Date Due 12/11/12. The unit is in good to great cosmetic condition with a scratch here or there. The top cover has some marks on it (see picture). The side handle rubble boots are missing (see picture). All buttons, knobs, and switches are good and intact. The serial # is B042281. The RF input level can be up to +30 dBm max and the frequency range from 50 kHz to 21 GHz without external mixers. Works with 120 and 240 voltage. We always re-check the item before we ship it. This makes sure the item is working when it left my shop.
