Section 7: Command reference Model 2651A High Power System SourceMeter® Instrument Reference Manual
7-134 2651A-901-01 Rev. A / March 2011
Details
To achieve optimum noise rejection when performing measurements at integer NPLC apertures, set the line
frequency attribute to match the frequency (50 Hz or 60 Hz) of the AC power line.
When using this command from a remote node, localnode should be replaced with the node reference, for
example node[5].linefreq.
When this attribute is set, the localnode.autolinefreq attribute is automatically set to false. You can
have the instrument automatically detect the AC power line frequency and set this attribute with the line
frequency detected when the instrument power is turned on by setting the localnode.autolinefreq attribute
to true.
Example 1
frequency = localnode.linefreq
Reads line frequency setting.
Example 2
localnode.linefreq = 60
Sets the line frequency to 60 Hz.
