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
