I have a Cushman CE-15 spectrum analyzer that was about 30 to 40 dB low in measuring signals. Traced the problem to the 2.1 Ghz bandpass filter. Looks like someone broke off the loop going to one of the connectors.
Anyone on this group have one they are parting out and can PART with the 2.1 Ghz bandpass filter part number 2600? Thanks; David
