We are working on trying out the UGF servos, and wanted to take loop measurements with and without the servo to prove that it is working as expected.  However, it seems like new DTT is not following the envelopes that we are giving it. 

If we uncheck the "user" box, then it uses the amplitude that is given on the excitation tab.  But, if we check user and select envelope, the amplitude will always be whatever number is the first amplitude requested in the envelope.  If we change the first amplitude in the envelope, DTT will use that number for the new amplitude, so it is reading that file, but not doing the whole envelope thing correctly.

Thoughts?  Is this a bug in new DTT, or a pebkac issue?
