[dsg-hdice] Found a built in averaging and referencing feature on sweep tab of Zurich lock-in amplifier

[Tyler Lemon]

Hi Xiangdong and Tom,

After our meeting, I ran a test sweep with the Zurich lock-in amplifier. While it was running I was looking around the sweep tab's options and found a sweep mode that lets you set a number of samples to take at each frequency during a sweep. I also saw on the "History" tab in the sweep tab there is a "Reference" option. These two options seem to result in what we are trying to do with the fsNMR program.

So you all can look at it, attached are three screenshots with what to click along with the steps below.

1. Go to settings tab on right of sweep tab
2. use drop down menu to change application to "Parameter Sweep Averaged"

3. Click "Advanced" button on settings tab
4. Enter averaging settings

At this point you'd run a sweep as normal. For the reference feature:

5. Go to history tab on sweep tab
6. select result to use as reference
7. click "Reference" button
8. Click button to toggle reference "on"

The next sweep you'd run will be referenced to whatever you selected in step 6. An example result after averaging is in the amplitude plot for screenshot1.jpg and in the attached CSV file.

I look forward to hearing what you think about and find with these options.

-Tyler
