Found a glitch in the moku I think people should be aware of.

I don't know what causes it but there have been multiple instances where the moku thinks its outputing the correct voltage but there is no signal coming out of the output port. Ex: While measuring several transfer functions today, I measured a TF with and without the high voltage amplifier (same set up as 11481). I took a TF using the high voltage amplifier, unpluged both BNCs from the HVA, connected them in order to bypass it, and went back to take the transfer function. Functionally nothing should change when doing this but when I attempted it, the transfer function was garbage. I eventually realized that even though it said there was an excitation signal on, nothing was actually coming out of the output (confirmed with a volt meter and oscilliscope). You even see the proper voltage at the closest test point to the output, but still no signal actually coming out of the output. Closing the moku app and reopening it did not fix it. Exiting out of the multi-instrument mode, opening up any random function in single instrument mode (I opened the oscilliscope), and opening MIM again fixed the issue.

Just putting this here in case people encounter this bug. Or maybe if anyone has an explanation for this please feel free to comment below. This may be worth a moku instruments forum post as well.
