Line frequency configuration
The factory configures the Series 2600B to automatically detect the power line frequency (either
50 Hz or 60 Hz) at each power-up. This detected line frequency 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 back out of the menu structure.
To configure the line frequency from a remote interface:
Set the localnode.linefreq or the localnode.autolinefreq attribute. The following
programming example illustrates how to set the line frequency to 60 Hz:
localnode.linefreq = 60
The following programming example illustrates how to remotely configure the instrument to
automatically detect line frequency at each power-up:
localnode.autolinefreq = true
Fuse replacement
A rear panel fuse drawer is located below the AC receptacle (refer to Rear panel (on page 2-6)). This
fuse protects the power line input of the instrument. If the line fuse needs to be replaced, refer to Line
fuse replacement (on page A-1).
