[dsg-hdice] Boxcar Averager Trial Dates

Hi Tom,

I was able to set up everything with your changes, but I'm not sure it's working correctly.

It seems like the boxcar averager should use a constant reference frequency, but I am unable to change it from oscillator 1 (whose frequency is being swept by the sweeper module). Every time I use the GUI to change the boxcar's reference to oscillator 2, it automatically gets forced back to oscillator 1.

The only thing I can think of to get oscillator 1's frequency to be a constant frequency is to change it so Signal Output 2 goes to the PD. This would let oscillator 2 be used for the frequency sweep while oscillator 1 can be set to stay constant for the boxcar averager.

Have you tried out the boxcar averager? Maybe there's something I'm missing.

Tyler

Hi Tyler,

I changed the connections so that Aux Output 1 goes to Signal Input 1,
Signal Output 1 Goes to the PD and Returns from the PD to Signal Input 2.
The Lock-In amplifier is now free to use.
