OUTPUT 725; ":SENS:DATA? BER”

ENTER 725; value$

PRINT value$ ! BER value after 2 seconds

WAIT 3

5.6 Examples

The following programming example assumes the user is programming with

Agilent BASIC, a simple interpretative language that is convenient for

instrument programming.

For the example programs below, the device being programmed is located at

GPIB device address 725. The actual address varies according to how you have

configured the GPIB bus for your own application. For information to change

the bus address see Section 5.

This first block of code shows how to initialize the instrument and check the

GPIB subsystem for errors.

10 OUTPUT 725; "*IDN?" ! request the instrument ID string

20 ENTER 725; result$ ! read the return string

30 PRINT result$ ! print the results to stdout

30 OUTPUT 725; ":SYSTEM:ERROR?" ! check for errors

40 OUTPUT 725; "*RST" ! reset the BERT
