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.
