Tek 2754P LO adjustment |
|
|
Hello everybody:
I am adjusting the LO hardware of my 2754P and there are some things that I
can not find or undestand:
After pressing shift 0 , loops calibration, overall system option the first
message is:
Connect a DVM on TP1058...etc (no problem )
(the meter shows 17mV)
Adjust frequency control
for a reading of 0.000 +/- 2mV
(problem WHICH FREQUENCY CONTROL?? OR POTENTIOMETER OR RESISTOR???)
The freuquency control board???
2.Connect a DVM on oint B of the controlled oscillator board and ground..
WHERE THE HECK IS POINT B AND WHERE IS THE CONTROLLED OSCILLATOR BOARD???
Thank you your help
