Using the LAN to Control the Analyzer

Controlling Your Analyzer with SICL LAN and HP/Agilent

BASIC for Windows

Before you can use HP/Agilent BASIC for Windows with SICL LAN, you need to set up VISA/SICL LAN I/O drivers for use with your BASIC applications. Consult your BASIC documentation for information how to do this.

To set up SICL LAN for BASIC, add the following statement to your AUTOST program (all on a single line):

LOAD BIN “GPIBS;DEV lan[analyzer IP address]:GPIB name TIME 30 ISC 7”

Replace analyzer IP address with the IP address of your analyzer, GPIP name with the GPIB name given to your analyzer, and 7 with the logical unit number.

For example, the following LOAD statement should be added to your

AUTOST program for the parameters listed below:

analyzer IP address 12.22.344.225

analyzer GPIB name inst0

logical unit number 7

timeout value (seconds) 30

LOAD statement (all on a single line)

LOAD BIN “GPIBS;DEV lan[12.22.344.225]:inst0 TIME 30

ISC 7”Consult your BASIC documentation to learn how to load the

SICL driver for BASIC.

After the SICL driver is loaded, you control your analyzer using commands such as the following:

OUTPUT 718; “*IDN?”

ENTER 718; S$

where 18 is the device address for the analyzer.

See the BASIC example program in this chapter for more information.
