Table 2 - Oscilloscope Settings
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.
