Kurt,
Thanks for posting the 535_545 operator's handbook.
Can someone in the group explain what the stability control in the trigger circuit actually does electronically?Why was it dropped (not needed?) ?in later generations of Tek scopes?
I understand the intended operation of the stability control (as explained in the handbook) and recall using it with success with a 500 series scope.? But I've always been curious what it actually did in the trigger electronics.I suspect it sets?the high frequency?rolloff?in the trigger circuit.?
