MEASurement Commands 2
N1911A/1912A P-Series Power Meters Programming Guide 165
[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.
