Thanks meBigGuy. We measured the voltage on the reference signal and it was only around 140 mV so we switched our detector and got the reference frequency where it should be. Thanks a bunch for the quick response!Sent from my iPhone using Physics Forums
So here is my dilemma:
We have our SR830 in a MOKE set-up. The modulation of the laser is with a chopper at approximataly 336 Hz. The reference signal is not being picked up by the SR830, but using the same cable the reference frequency is coming up on our oscilloscope. ie, plug the cable...
