2 MEASurement Commands
152 N1911A/1912A P-Series Power Meters Programming Guide
[a] 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 default from the right. The parameter DEFault is used as a place holder.
Specifying DEF leaves the parameter value unchanged.
[b] When the measurement result is linear this parameter represents the number of significant digits. When the measurement result is
logarithmic 1 to 4 represents of 1, 0.1, 0.01 and 0.001 respectively.
[c] N1912A only.

Error Messages
– INITiate:CONTinuous must be set to OFF on both channels, otherwise error
–213, “INIT ignored” occurs.
–If TRIGger:SOURce is set to BUS or HOLD on either channel, error –214, “Trigger
deadlock” occurs.
– If the resolution parameter is not the same as the current resolution setting on
the specified window, error –221, “Settings conflict” occurs.
source list 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 (N1912A) or A-A (N1911A).
