Initial Operation

This section provides a programming example to help verify correct module

installation and operation. Additional programming examples and procedures

are given in the next chapter.

The examples shown here use BASIC and SCPI (Standard Commands for

Programmable Instruments). The example assumes a factory set logical

address of 72 for the Agilent E1418A module and uses an Agilent Command

Module for command interpretation. Examples in ANSI C are given in the

next chapter.

Note This discussion applies to SCPI programming using the driver provided

with the module. The SCPI commands are described in Chapter 3 of this

manual. Appendix B of this manual describes direct register access.

Device Driver The Agilent E1418A module is shipped a driver CD. This CD contains the

SCPI instrument driver, VXIplug&play drivers, example programs, and

Agilent VIC (VXI Installation Consultant). Follow the instructions contained

on the CD to properly install the device driver.

The following example shows how to query the command module and

verify that the correct device driver is installed:

10 DIM A$[256]

20 OUTPUT 70900;"DIAG:DRIV:LIST?"

30 ENTER 70900;A$

40 PRINT A$

50 END

In this example, the command module is located on GPIB (interface address 7)

and uses a primary address of 09. Responses to this example vary depending

upon the drivers loaded on your system. A typical response might look like:

E1418,E1418,A.01.00,RAM;SWITCH,SWITCHBOX,A.08.00,RAM;

SYSTEM,E1405A,A.08.00,ROM;IBASIC,IBASIC,A.04.02,ROM;

VOLTMTR,E1326A,A.05.00,ROM;SWITCH,SWITCHBOX,A.07.00,

ROM;COUNTER,E1332A,A.04.02,ROM;COUNTER,E1333A,A.04.02,

ROM;DIG_I/O,E1330A,A.04.03,ROM;D/A,E1328A,A.04.02,ROM

Verify that the string “E1418,E1418,A.01.00,” is located somewhere

within the returned string.
