Just picked up a HP1740A oscope and need to fix it. The problem is that
it will not calibrate . I have the repair manual but you need a phd to understand it. So maybe someone could give some advice
this is the image I get with volts set to .5 and time set main div .2
I tryed to adjust the prob resistor but it has very little effect.
When connected to a wavetek 180, can get a sine,triangle and square wave but only at high hf 1meg setting.
Also the dc volt measure will not work. For example if connected to a nine
volt bat it will not show the image. or any dc voltage. however, it will
show the amplitude of a sine on hf.
thanks for any help
