I Want to display a mathematical post processed output from two measured channels.
I am measuring the output of a mixer. The I channel voltage is measured on Channel 1 and the Q channel on Channel 2. If I do the trigonometry, I can get the phase info or the amplitude info over time. Triggering is on another channel and there is averaging.
Is there a way to do this internally like with a plugin card?
Or is it best thru labview?

Hello,

You can have the scope calculate phase and amplitude using automated measurements. Phase can be found as the fourth option on page 3, and amplitude is the fourth option on page 4. Unfortunately the TDS3000 does not have the capability to log this data internally. You will need to use a program such as labview to capture and log the measurements.
