application.
NOTE
You can specify differential and/or common mode channels using the following convention.
If you have differential or common mode channels enabled (using either the
:CHANnel<N>:DIFFerential or :CHANnel<N>:COMMonmode commands) then:
•
:CHANnel1 would refer to the Channel 1 - Channel 3 differential channel
• :CHANnel2 would refer to the Channel 2 - Channel 4 differential channel
• :CHANnel3 would refer to the Channel 1 + Channel 3 common mode channel
• :CHANnel4 would refer to the Channel 2 + Channel 4 common mode channel
