PDP Installation

Download/Clone PDP from https://github.com/uva-spin/e1039-target-controls (see the PDP folder on this Git repository)
Connect all the devices as it was explained in the ORC files on NMR ORC
Install LabView Software
Open "Measurement & Automation Explorer"
Select "Device and Interfaces" > "NI PXle-1071 PXIChassis 1" on the list (see the screenshot below)
Install the required drivers. Notice that there is one "caution" mark appeared in this example for missing driver for "PXI-GPIB" (please see the screenshots below)
Rename the PXI names as it appears in the following screenshot
Select "NMR Tune" mode and check the oscilloscope after tuning the Q-curve
Then you will need to edit the B28_Setup file's "Path" with the correct path where your "events.csv" file will be recorded.
Click on "Enable Buttons" and click on "New base File" (the one below "Enable Buttons") and then click on the "Disable Buttons".
Select "Create a New Baseline"
Then make sure that you selected "Top Proton" as the target and modify number of sweeps (eg: it will take ~320 seconds for 5000 spweeps; you can reduce/change number on that text box and press "enter" after modification).
After that, press "One Point" and wait. PDP will take some time (you will see the count-down) and take the measurement (see the bottom left plot)

Tuning steps of the Q-meter

Start with the "Diode" mode to figure-out the correct cable length: connect the coaxial cable to "Diode mode" on DIO box interface
We use the scale (in the oscilloscope) of the off-set of the Diode to know whether we are in/out side of the Q-meter's operational parameters within a reasonable deviation from lambda/2
i.e. if there is no cable connected (or the cable length is very far away from lambda/2), then the DC off-set will be about ~12V on the Diode.
In order to have it working correctly, you need to have ~3V (or less).
