Line fuse and
power receptacle
Connect the line cord to the power receptacle and a grounded AC
power outlet. The line fuse, located just above the power
receptacle, protects the power line input of the instrument. For
safety precautions and other details, see
LAN port
Supports full connectivity on a 10 Mbps or 100 Mbps network. The
2470 is a version 1.4 Core 2011 compliant instrument that
supports TCP/IP and complies with IEEE Std 802.3 (ethernet
LAN). See
(on page 2-16).
USB port
USB-B connection for communication, control, and data transfer.
For details, see
(on page 2-25).
Digital I/O port
A digital input/output port that detects and outputs digital signals.
The port provides six digital I/O lines. Each output is set high
(+5 V) or low (0 V) and can read high or low logic levels. Each
digital I/O line is an open-drain signal. Refer to
page 8-12) for information.
TSP-Link ports
TSP-Link
®
system expansion interface, which builders of test
systems can use to connect multiple instruments in a master and
subordinate configuration. TSP-Link is a high-speed trigger
synchronization and communication bus. For details, see
TSP-Link System Expansion Interface
LAN reset
Reverts the LAN settings and the instrument password to default
values. See
(on page 2-24) for more
information.
IEEE-488 port
GPIB connection; the default setting for the 2470 is 18. Refer to
(on page 2-11).
Turn the 2470 output on or off
You can turn the 2470 output on from the front panel or by sending remote commands.
Turning the 2470 output off does not place the instrument in a safe state (an interlock is
provided for this function).
Hazardous voltages may be present on all output and guard terminals. To prevent electrical
shock that could cause injury or death, never make or break connections to the 2470 while
the instrument is powered on. Turn off the equipment from the front panel or disconnect the
main power cord from the rear of the 2470 before handling cables. Putting the equipment into
an output-off state does not guarantee that the outputs are powered off if a hardware or
software fault occurs.
When the source of the instrument is turned off, it may not completely isolate the instrument from the
external circuit. You can use the Output Off setting to place the 2470 in a known, noninteractive state
during idle periods, such as when you are changing the device under test. The output-off states that
can be selected for a 2470 are normal, high-impedance, zero, or guard.
See
(on page 4-16) for additional details.
