Note: Use the same settings on the oscilloscope when capturing
waveforms for the two Slave bridges. If you are using a 2-channel
oscilloscope, then first capture two waveforms and move them onto a
wavestar worksheet and after that capture the remaining waveforms
and move them onto the same wavestar worksheet.
