1. The mnemonic
parameter used in the command sub-systems. The parameters must be entered in
the specified order. If parameters are omitted, they will default from the right. The
parameter DEFault is used as a place holder. Specifying
value unchanged.
2. When the measurement result is linear this parameter represents the number of
significant digits. When the measurement result is logarithmic 1 to 4 represents a
resolution of 1, 0.1, 0.01 and 0.001 respectively.
3. E4417A only.

Description/Default
This channel list specifies the
channels used to calculate the
difference.
If unspecified and the current
window setup is a difference
measurement then this difference
setup is used, otherwise it defaults
to channel A-B (E4417A) or A-A
(E4416A).
DEF means DEFault. This is not equivalent to the DEFault
This command configures the
upper window to make a
difference measurement of
channel A - channel B with
relative mode on, using the
current sensor range and a
resolution of 1 on both channels.
