34980A Measurements Made Easy
Application note
Abstract
A signiicant and understandable concern
with new test system setup is becoming
familiar with and programming the
instruments. Learning the steps needed to
control an instrument can be time consuming
if not dificult. Many hours can be spent
reading through syntax manuals and
performing trial and error tests. When a test
system is updated only occasionally, it may be
hard to remember the instrument commands
and steps required to make changes.
This document includes examples with the
few steps needed to make measurements
using the 34980A’s 1) front panel, 2)
built-in web interface, and 3) Command
Expert software. In a matter of minutes
the 34980A will be making measurements,
recording the commands sent to the 34980A
and creating executable code for your choice
of application software.
Overview
Introduction
Learn to make measurements using the Keysight Technologies, Inc. 34980A Switch
Measure System (34980A) front panel—remotely from a web page or by programming.
Also, see how easy the 34980A is to control using Keysight’s Command Expert.
Controlling the 34980A can be done easily by three dif-ferent methods: the front panel
pushbuttons, the built-in web graphical user interface or by programming directly. Initial
testing and coniguration are achieved quickly by using the front panel or the web
interface. Developing a software control that can be used in automated test or data
acquisition applications is often based on the results of the initial test and coniguration.
This document will demonstrate the steps used to setup, test and program the 34980A.

measurement examples; however, any of the 34980A
modules can be controlled using similar steps/commands.
The 34921A module and terminal example will be set for the
following measurements:
Addressing module channels
To send a command to make a measurement on a speciic
channel, place the module slot number irst and the channel
number last, illing in spaces with zero for four digits. For
example: addressing channel 4 of the multiplexer module
installed in slot 1 uses the channel address of 1004. If the
multiplexer were installed in slot 2 the address 2004 would
be used.

34980A Measurements Using the Built-In
Web Graphical User Interface (GUI)
The 34980A’s web GUI does not require any additional software to communicate with a computer and offers access to
the 34980A from anywhere around the globe with just a LAN connection. The 34980A’s LAN connection is not only an
easy-to-use interface for simple test, but also a great advantage for distributed test systems found in applications such as
satellite and avionics tests.
Figure 3. Keysight 34980A.
Connect the 34980A’s web interface directly to a
computer:
1. Use the 34980A’s LAN port to connect to a computer
and open a web browser (such as Internet Explorer,
Firefox, Netscape, or google).
2. On the front panel of the 34980A, press the [Utility]
button and turn the knob to select Remote I/O.
3. Press the [Utility] button again and turn the knob to
select LAN.
4. Press the [Utility] button and turn the knob to select
YES to Enable LAN.

Note: since the 34980A is connected directly to the PC
there is not a DHCP server (a networks’ DHCP server will
assign client computers a unique IP address). Keysight’s
LXI instruments such as the 34980A, have an “auto IP”
function that will assign an IP address for using the web
interface when directly connected to a computer rather
than a network.
9. Open your preferred web-browser and enter the
34980A’s IP address in the address bar and click Enter.
Example: enter http://169.254.9.80 and the
34980A’s web home page will appear.

How to make a temperature measurement
The Command pane in Command Expert includes
documentation and command syntax for the selected
command. Here is an example of the details you will see for
temperature measurements.
The syntax guide tells us that an instrument temperature
measurement requires three steps:
1) Set measurement units (UNIT command)
2) Make reference junction temperature measurement
(SENSe command)
3) Make temperature measurement on selected
channel (MEASure command).
Step 1. UNIT;TEMPerature Command
Conigures the units for the temperature measurement you
would like to make.
1. In the Browse pane, click UNIT:TEMPerature.
2. Enter the following parameters in the Command pane:
a. Units: you can choose F, K or C
b. Ch_list: @1002
3. Click on <Perform>
Notice that each command sent is recorded in the bottom
“Sequence” pane.
The sense command for the 34980A does not need to be
repeated every time a measurement is made. It should be
sent periodically or whenever the ambient temperature
changes.
1. In the Browse pane, click
SENSe:TEMPerature:Transducer:TCouple:
RJUNction:TYPE
2. Enter the following parameters in the Command pane:
a. Source: INTernal
b. Ch_list: @1002
3. Click on <Perform>
Step 3. MEASure command
1. In the 34980A Browse pane, click
MEAS:SCALure:TEMPerature
2. Enter the following parameters in the Command pane:
a. Probe_type: Tcouple
b. Type: J
c. Range: AUTO
d. Resolution: DEFault
e. Ch_list: @1002
3. Click on <Perform> and see the temperature
measurement appear in the Sequence pane
4. If you wish to repeat the measurement, click on the
green play ► button in the Sequence pane.

Set a 34980A IP Web Address
Figure 3. Keysight 34980A.
Set or VIEW a 34980A IP Web Address from the 34980A’s
front panel:
1. Press the [Utility] button and turn the knob to Remote I/O
2. Press the [Utility] button and turn the knob to LAN
3. Press the [Utility] button and turn the knob to YES to
Enable LAN
4. Press the [Utility] button and turn the knob to MODIFY
for LAN Settings (or VIEW to see currently set IP
address and not change)
5. Press the [Utility] button and turn the knob to NO for
Reset LAN
6. Press the [Utility] button and turn the knob to OFF for
DHCP* since the 34980A is connected directly to your
computer and not a server
7. Press [Exit Menu]
8. Cycle the power
9. Wait for about 1 minute to let the LAN assign an IP
address
10.Using the [Utility] button and knob in the same manner
as steps 1 thru 3, go to Remote I/O>LAN>YES>VIEW
11. Turn the knob to ind the IP address.
Example: 169.254.9.80
12. Record the address
Press [Exit Menu]
There is not a DHCP server since a computer is connected
directly to the 34980A rather than through a network.
Keysight’s LXI instruments have an “auto IP” function that
will assign the IP address. Note that the last few digits in
the product’s model number are used in the IP address.
This is the general case for Keysight instruments.
In the Stand-Alone DMM Mode, the internal DMM makes
measurements of the signals present on the analog buses.
In this mode, you have full control of what channel relays
are closed and connected to the appropriate analog bus
for the measurement. You can route your signals directly to
the internal DMM using the 34980A multiplexer and matrix
modules.
For 4-wire resistance measurements, the instrument
automatically pairs channel n in 34980A Bank 1 with
channel n+20 in Bank 2 (for switch modules: 34921A,
34923A, 34925A) or n+35 (for switch modules: 34922A,
34924A) to provide the source and sense connections. For
example, make the source connections to the HI and LO
terminals on channel 2 in Bank 1 and the sense connections
to the HI and LO terminals on channel 22 (or 37) in Bank 2.
