HP / Agilent / Keysight · Spectrum analyzer · c.1987–c.1992
HP brought out the 8562A and 8562B as MIL-rugged portable microwave spectrum analyzers, new in its 1988 catalog, and called them the fifth generation of HP analyzers. The 8562A covers 1 kHz to 22 GHz with tracking preselection, synthesized tuning and a built-in frequency counter, warms up in five minutes, and was built to survive 30 g shocks. HP said it would even slide under an airplane seat, though at 44 pounds it's portable the way a toolbox is. A speaker and AM/FM demodulation let you listen to a signal, and HP-IB is standard. It joined the 8560 series, and by the mid-1990s HP had moved that line on to the E-series models. The 8562B is the unpreselected version for work below 2.9 GHz. Look for the front impact cover and the 85629A Test and Adjustment Module, which plugs into the back and runs diagnostics.
Options and accessories
Check the listing photos and the rear panel against this list, and ask the seller about anything you can’t see. A missing option or probe should come off the price.
The RF input is rated for 0 V DC and takes +30 dBm only with 10 dB or more of attenuation, so treat any hint of overload or a DC-coupled hookup as a risk to the front-end mixer. Ask about the CRT too, since a dim or burned screen on a 1980s display is hard to put right.
New to used bench gear? How to check used test equipment covers self-tests, fuses, the voltage selector and shipping, and what “calibrated” means in a listing.
Buying guide
There's one complete 8562A for sale, sparksman11's at $760 delivered, so this isn't a market read, and that figure is just this listing's price. Everything else under the name was boards, panels and YIG/YTO modules. It's titled tested and the photo shows the CRT lit with a trace, so ask for a photo with the CAL OUTPUT connected to the RF input showing a clean single peak, a close look at the Type N input's center pin, and how the fan sounds. At 44 lb it's easy to break in transit, so ask for a double box with foam on every side and the front impact cover on if they have it, and confirm it's set for 115 V.
