[dsg-hdice] Boxcar Averager Trial Dates

Hi Tom,

How is the Zurich Lock-in amplifier set up? I'm guessing it is set up with all the typical connections you all have used in the past for measurements using it? From Ed's demo, it looks like we'd need to connect one of the lock-in amplifier's auxiliary outputs to the second lock-in amplifier input and then use that input for the boxcar averager.

I've been looking at the boxcar averager and sweeper since your last email and have noticed a few things. It seems like the the boxcar averager wants you to use oscillator 1 as its reference frequency. With the current set up, I'm not sure if this is helpful since currently, that oscillator is the one that changes in frequency when you run a sweep. From this finding, it seems like for the boxcar averager, we'd need to change the output that goes to the NMR coil from output 1 to output 2.

 I'm not sure if there's much else I can do or try without being able to change out the cables or anything. With that, I can release the lock-in amplifier so you or anyone else can take a look.

Tyler

Hi Tyler,

The Zurich Lock-In Amplifier is all yours now.
