MEASurement Instructions
CONFigure[1|2][:SCALar][:POWer:AC]:DIFFerence [<expected_value>[,<resolution>[,<source list>]]]
2-14 HP E4418B/E4419B Programming Guide
Example
1. The mnemonic DEF means DEFault. This is not equivalent to the DEFault
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
DEF leaves the
parameter 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.
source list This channel list specifies between
which channels the difference is
calculated.
If unspecified and the current
window setup is a difference
measurement then this difference
setup is used, otherwise it defaults
to channel A-B.
(@1),(@2)
(@2),(@1)
CONF2:DIFF DEF,1,(@2),(@1) This command configures the
lower window to make a difference
measurement of
channelB-channel A, using the
current sensor range and a
resolution of 1 on both channels.
