Instrument Manager and Spyrelet Conflict(?)

[aidanj5]

When we run our experiment with the instrument manager open, the experiment will run briefly, and very soon stop suddenly while closing the instrument manager. The error says that it stops when it tries to set the frequency on our signal generator.

To Reproduce Connect to the instrument servers with your instruments. Open the instrument manager, and then open your spyrelet. Run your ODMR. Upon setting the frequency to ~ 2.8333 Ghz, which is our third step, we see the following error.

It should not produce this error.

I'm running this on Windows 10, installed from conda-forge, version .4.5 (I believe, it has the updated instrument manager with working arrows that set the value).

If it matters, we recently configured our system such that we are switching between computers. We switch over some USB connections of our other instruments, but the signal generator connects via ethernet.

@aidanj5 can you explain this switching in more detail? Also, if you run conda list inside your environment, it should show you the version number. Please confirm that it is indeed 0.4.5.

@mtsolmn this looks like a pysignal related issue

[aidanj5]

Did not know about conda list. NSpyre is version 0.4.5.

Closing this issue because it is tied to #37 .
