common mode display scale and offset to track the acquisition scale and
offset.
<N> An integer, 1 - 4
Example This example sets the channel 1 - channel 3 differential channel display
scale and offset to track the acquisition scale and offset.

Returned Format
[:CHANnel<N>:DISPlay:AUTO] {1 | 0}<NL>
Example This example places whether or not the channel 1 - channel 3 differential
channel display scale and offset is tracking the acquisition scale and offset
in the variable varAuto, then prints the contents of the variable to the
computer's screen.
myScope.WriteString ":SYSTem:HEADer OFF"
myScope.WriteString ":CHANNEL1:DISPLAY:AUTO?"
varAuto = myScope.ReadNumber
Debug.Print FormatNumber(varAuto, 0)
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
