Controlling the Test Set
Controlling the test set and making measurements
Keysight U3020A is a “slave” instruments. A controller must be used to control the Test Set. There
are two methods that can be used to control the Test Set.
– Using LAN connection
– Using GPIB connection
Once the connection between the Controller and the Test Set has been established (LAN or GPIB),
the Test Set can be controlled using SCPI commands.
LAN connection using your companies intranet
Connect the Test Set and your controlling computer to an active instrument LAN line. Open the
internet browser application on the computer. Enter this default web address on your browser
application: http://U3020as26-xxxx
The Welcome screen for the instrument should be viewable if the LAN connection is working.

Commands
Once the connection between the controller and the Test Set has been established (LAN or GPIB),
the test set can be controlled using SCPI commands. Refer to
Test set control commands
The Test Set has predefine sequence command sets defined at the factory and stored in the
non-volatile memory of the controller module. If the specified sequence name is not currently
stored in the memory, due to corrupted program or accidentally deleted, an error will be
generated. Refer to the
of this manual for instructions to remedy this issue.
Syntax
ROUTe:SEQuence:TRIGger <command>
Parameters
Refer to Table 6 for commands use to control the Test Set’s programmable switches.
Example
The following executed sequence command, “SEL_PORT1”, will position the RF switches to create
a signal path through Port 1, Input to Output for Channels A and B. All other remaining Port Inputs
will be terminated by an internal 50 Ohm load.
ROUT:SEQ:TRIG SEL_PORT1
NOTE
The last four digits in the web address (xxxx) are the last four digits of the instruments serial
