I logged in to hdicenm2 with the hdice account to take a quick look at the power settings in the fsNMR.vi code to make sure it wasn't anything obvious causing those symptoms.</div>

I couldn't see/find anything and manually running the set/read VIs (the only 2 I ran [it started at -50, I changed it to -60, then back to -50]) for the attenuator A works fine.</div>

Also the dual power supply vi was on the screen when I logged in but not running; is that to be expected?</div>

<div>Hi Tyler,
<div><br>
</div>
<div>We successfully transferred a polarized target from DF to PD and measured target polarization there with NMR rack2, and then transferred it to IBC in UITF.</div>
<div><br>
</div>
<div>Since the NMR signal of a fully polarized target is huge, I had to use very low power, such as-40, -50, and -60dBm. </div>
<div><br>
</div>
<div>The fsNMR on the control rack did not allow me to run with those power, and sending high power instead. -30 was fine, but -50dBm was changed to -18dBm by the fsNMR VI, and -40dBm was changed to -24dBm. The error pictures are attached here. Please take
a look at the fsNMR ASAP. I will be at UITF tomorrow morning to check the vi when you are done.</div>
<div><br>
</div>
<div>Since the IBC magnets are controlled by the rack2 pc also, please don’t change the magnet settings. The testing frequency range should be between 1 and 2 MHz; and power is -60, -50, -40, and maybe -30, to avoid accidentally de-polarize the target. The
IBC solenoid is at ~0.9Tesla.</div>

<div>Thanks, </div>
