Haven't been very active for some time. When I now started my old HP-8563E it shows two faults;
1. when I connect any CW-signal I get sidebands about 400-450kHz on each side of the carrier. These are shown about 53dB below the carrier and are on all CW-signals. (Not when I look with another analyzer.)
2. Noise level seems very high. I get a broad band of noise with the analyzer after reset and there isn't any dark part of the screen below the "noise band".
No errors recoreded.
