How do you configure a Scope to do math measurements?

[gsflat]

I am trying to use the IviScope driver with a TDS 3054a Scope and I am trying to configure the scope for MATH measurements. I see in the IviScope documentation that you can configure the MATH channel through the SFP but how do you configure it through the method calls that are available through LabWindows/CVI?

Math channels are not specified in IviScope specification. NI SFP does not use math opertaion inside instrument, but all these math operations are calculated in your PC. Tektronix tkds30xx has following functions for math channels:
tkds30xx_EnableMathChannel
tkds30xx_ConfigureMathChannel
tkds30xx_ConfigureMathChannelFFT

All these functions are driver specific and they are not interchangeable. If you want use class defined interface, you should calculate these math operation in your PC.

You can query this math waveform with stanadrd read and fetch functions:
tkds30xx_ReadWaveform
tkds30xx_FetchWaveform
Channel name is "MATH"
