SETLevel sets the main trigger level to half way between the MIN and MAX
amplitudes of the trigger source input. This is equivalent to pressing the
front-panel SET LEVel TO 50% button.
This argument works differently with AMI Communications Triggering settings.
Specifically, when AMI is chosen, this command measures the peak-to-peak
level and sets an upper threshold value at 75% and a lower threshold value at
25% of the peak-to-peak value. If the pulse form is CMI, NRZ, or an Eye
Diagram, the level is set to 50%.
TRIGGER:MAIN SETLEVEL
sets the main trigger level mid way between MAX and MIN.
TRIGger:MAIn:COMMunication:AMI:PULSEForm
TDS 500C & 700C Only
Sets or queries the communication trigger AMI pulse form to one of three
possibilities.
