Using the LAN to Control the Analyzer

Controlling Your Analyzer with SICL LAN and BASIC for UNIX (Rocky Mountain BASIC)

Before you can use Rocky Mountain Basic (HPRMB) with SICL LAN, you will need to set up the SICL LAN I/O drivers for HPRMB. Consult your system administrator for details.

Create a .rmbrc file in your root directory of your UNIX workstation with the following entries:

SELECTIVE_OPEN=ON

Interface 8= “lan[analyzer IP address]:GPIB name”;NORMAL

Replace analyzer IP address with the IP address of your analyzer, and GPIB name with the GPIB name given to your analyzer. Also replace the “8” of Interface 8 with the logical unit number. Consult your HPRMB documentation for the exact syntax.

After your SICL driver is configured correctly on your UNIX workstation, you control your analyzer using commands such as the following:

OUTPUT 818; “*IDN?”

ENTER 818; S$

where 18 is the device address for the analyzer.
