Hello, I have got a SR250 boxcar averager. I have got the manual, but still I don't understand how to use the active baseline subtraction. According to the manual, first I have to move the switch on the rear panel in TOGGLE position (ok, I did it). Then, in order to toggle with each other trigger, I should use the ACTIVE BASELINE SUBTRACTION output in the back. How?
In the experiment, I have an emitting diode driven by a pulse generator. The detected light is my signal input at the boxcar. The trigger comes from the pulse generator. Unfortuantely there is a fluctuating baseline I want to get rid of. How can I connect my setup? Do I need to double somehow the frequency, so that there will be two gates, one at the signal, the other at the baseline? Or this is done by the pulse generator?
I don't understand
Thanks
Simone
