1-5 Sending SCPI Commands
SCPI commands can be sent to the LMR Master though any Virtual Instrument Software
Architecture (VISA) controller. VISA is a commonly-used API in the Test and Measurement
industry for communicating with instruments from a PC. The physical connection between
the PC and the LMR Master can be Ethernet or USB.
NI-VISA is the National Instruments implementation of the VISA I/O standard. Information
and downloads are available at the following link:

The following example describes the verification that a VISA controller can detect the
LMR Master. The images shown and the instructions for your instrument and software may
differ from the examples in this manual.
1. On the PC, run VISA Interactive Control and double click on the LMR Master.
Note
Before remote operation, confirm that the instrument is not in the Menu screen.
Sending commands while this screen is displayed is an invalid operation. Refer to
the instrument User Guide for information on the Menu screen.
