Hi:
My calibrator was giving me trouble. The 1 Meg resistor was 6 Meg and the 10 kohm about 16 kohm. After replacing these it seems to work ok into another receiver, but I measure about -5V at pin7 of V205 instead of -16.5 V. All the miniBNCs are not connected, but it doesn't look from the 21st century manual like that should matter. The older manuals I have on CD also have -16.5 V. Is this what a few of you measure?
Does anybody have a few thoughts? (The Rf stage is giving me grief so I want to get the easy stuff first).
My thanks in advance
Mke
