Check the listing for details. IFR2398 9kHz-2.7GHz RF spectrum analyzer ! Clean! Fully working!. Condition: Used. Listed at 899.99 USD. This is fully working, lightly used, tested spectrum analyzer taken from workbench. All tests pass. Covers 9kHz to 2.7GHz frequency range, may be helpful for RF development in most unlicensed bands (433, 960, 2400Mhz). Monochrome LCD. The pictures show the signal from 2.5GHz and 1GHz generator, and the signal with 100% AM modulation. In the picture of self test status, RBW is also "Pass" - It is a very short moment between test completion and switching to spectrum, so I could not catch it on camera. Very clean condition, I am also adding a padded soft travel bag, power and data cables, manuals on CD, so it is ready to do measurements. It has calibration seals, but it was not calibrated within last 5 years. I can add GPIB cable on request.
