Line frequency configuration
The factory configures the 2606B 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 virtual 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. 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
Fuse replacement
The power receptacle contains a fuse drawer (refer to
(on page 2-3)). This fuse protects
the power line input of the instrument. If the line fuse needs to be replaced, refer to
(on page A-1).
Remote communications interfaces
You can choose from one of several communication interfaces to send commands to and receive
responses from the 2606B.
You can control the 2606B from only one communications interface at a time. The first interface on
which the instrument receives a message takes control of the instrument. If another interface sends a
message, that interface can take control of the instrument. You may need to enter a password to
change the interface, depending on the access mode.
The 2606B automatically detects the type of communications interface when you connect to the
respective port on the instrument. In most cases, you do not need to configure anything on the
instrument. In addition, you do not need to reboot if you change the type of interface that is
connected.
The 2606B supports the following remote interfaces:
•
LAN. Local area network (LAN) communications provide the flexibility to build scalable and
functional test or data acquisition systems with a large degree of flexibility.
•
USB. Communicate with the instrument over a USB connection.
