HP E1418A manual Initial Operation

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 HP BASIC and SCPI (Standard Commands for Programmable Instruments). The example assumes a factory set logical address of 72 for the HP E1418A module and uses an HP 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 HP E1418A module is shipped a driver CD. This CD contains the SCPI instrument driver, VXIplug&play drivers, example programs, and HP 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]

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

30ENTER 70900;A$

40PRINT A$

50END

In this example, the command module is located on HP-IB (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.
