Usage
frequency = localnode.linefreq
localnode.linefreq = frequency
frequency
An integer representing the detected or specified line frequency of the instrument
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.
