Sets IDC as:
–
CHANnel<n>
where n = 2 or 3
–
WMEMory<n>
where n = 1, 2, 3, or 4 (only for linear waveform)
–
CONStant
–
CH2MCH3
: Sets to the resultant trace of channel 2 subtract channel 3.
[a]
–
CH3MCH2
: Sets to the resultant trace of channel 3 subtract channel 2.
[a]
Sets VDC as:
–
CHANnel<n>
where n = 2 or 3
–
WMEMory<n>
where n = 1, 2, 3, or 4 (only for linear waveform)
–
CONStant
Sets PGAIN as:
–
CHANnel<n>
where n = 1 or 4
–
WMEMory<n>
where n = 1, 2, 3, or 4 (only for linear waveform)
