  1. When using the scope from the Waveforms IDE, I can't get a visual of Channel 2. (Channel 1 works fine) I've tried using multiple USB ports and other computers. When I run calibration for the oscilloscope I get the following error message: "Check the connections!! The measured voltage on Oscilloscope Channel 2 is between: 30.269009276 V and 30.275477712 V. But it should be around: 0 V. It might be that the Arbitrary Waveform Generator 1 Offset is not calibrated correctly." I don't think the waveform is the issue, it reads as expected on channel 1. I could use some help.
  2. I am sending synchronized, phase-shifted pulses with the AWG on both AnalogOut channels on the Discovery2, using a custom application I'm writing in python. I am feeding the AnalogOut directly back to the AnalogIn with no additional hardware involved. I am trying to read the two AWG signals using the AnalogIn channels, but I can't get Channel 2 to report the signal. Instead, both signals are adding together and displaying as coming from channel 1, with the expected channel 2 signal showing up as negative voltages on channel 1. How do I separate the two signals? This is the chunk o
  3. Hi, I would like to add several custom measurements based on my Scope Channel 1 signal: 1. Current measurement through a 220 ohm resistor 2. Min and max Frequency measurement of the signal applied to the same 220 ohm resistor. For number 1 I clicked "Add Channel" -> Custom, and added C1/220 to the textarea. This resulted in a new channel in the scope.channel column. I then went to Measurements column and did "Add" -> Custom Channel -> Math 1. This added an M1 measurement to my measurements. I modified the default Javascript to the code below, which (if I understand
