Getting Started Guidelines to Remote GPIB Programming
Guidelines to Remote GPIB Programming
The TDSHT3 application includes an example of a Remote GPIB program for your reference as a program
example. Your Remote GPIB program should comply with the following guidelines:
Launch the application before sending any remote GPIB commands to the application (see the
program example).
Before running the GPIB commands, you can use the *IDN? variable to identify the oscilloscope
and ensure that the oscilloscope is responding.
GPIB commands do not work through LAN.
When the application processes remote GPIB commands, no messages are displayed.
For save, recall, and report generation, the successive file names should be different.
The application does not respond to commands that were sent before the application was activated.
To g ener

Launching the Application using Remote GPIB
You must manually set up the oscilloscope to launch the application.
The application uses the Remote
features. The set of Remote GPIB commands includes the variable names and variable values necessary to
select, configure, and run the measurements and to generate reports in the Remote GPIB program.
You can select and configure the measurements that you want to use with your Remote GPIB program.

Remote GPIB Commands
The Remote General Purpose Interface Bus (RGPIB) is another way of interfacing with the oscilloscope.
It allows you to control much of the functionality of the oscilloscope as defined by the software, from a
Remote GPIB controller.
You can use the following GPIB command to start the TDSHT3 HDMI Compliance Test Software:

How to Set and Query
1. The following command syntax sets the value to the variable:
VARIABLE:VALUE “<vari able name>”,“<variable value>”
The arguments <variable name> and <variab le value> are required in the order indicated.
2. The following command syntax queries the value of the variable:
