Line frequency configuration
The factory configures the 2600B to detect the power line frequency automatically at each power-up.
This detected line frequency (either 50 Hz or 60 Hz) is used for aperture (NPLC) calculations.
In noisy environments, you can manually configure the instrument to match the actual line frequency.
To configure the line frequency from the front panel:
1. Press the
MENU
key, then turn the navigation wheel to select
LINE-FREQ
,
and then press the
ENTER
key.
2. Turn the navigation wheel
to select the appropriate frequency and then press the
ENTER
key. To
configure the instrument to automatically detect line frequency at each power-up, select
AUTO
.
3. Press the
EXIT (LOCAL)
key to return to the main display.
To configure the line frequency from a remote interface:
Set the
localnode.linefreq
or the
localnode.autolinefreq
attribute. To set the line
frequency to 60 Hz, send:
localnode.linefreq = 60
To configure the instrument to automatically detect line frequency at each power-up:
localnode.autolinefreq = true
