Used Agilent E4402B 9KHz-3GHz colour spectrum analyser. This unit is in good condition and fully tested. We have validated the accuracy in our lab and the unit passes self calibration and self test without error. Please see the photos of the inbuilt frequency counter for 100MHz, 500MHz, 1GHz and 2GHz carriers, where it was found to be accurate to <0.1dB.
This is a really nice unit, and available at a great price!
