GPIB Tutorial and Examples

Exercise A - Establishing a Link

Originate a Call

Begin the program by setting the GPIB address variable Uut=714, then select commands

from section “GPIB Commands Used in Exercises” to carry out the following actions:

❒ Preset the Agilent 8922M/S and set up the paging IMSI and external cable loss, zero

the power meter.

❒ Page the mobile.

❒ Establish a program loop to wait for the mobile to answer the call.

❒ End the loop when the mobile answers or when too much time has elapsed.

Tips:

The BASIC REPEAT UNTIL loop is useful in this application. The loop can be used to

keep checking the Agilent 8922M/S call status until the returned variable becomes equal

to “CONNECTED” or a time-out counter is exceeded. Place a WAIT 1 statement inside

the loop so that the Agilent 8922M/S call status is checked once per second. For more

help, look at the ‘PAGE THE MOBILE AND ESTABLISH A CALL’ section of example

program 1 in section “Example Programs”.

End the Call

Add additional lines to your program to end the call. Select the GPIB commands from

“GPIB Commands Used in Exercises” and use the same structure as for call set up. This

time, wait for the status to become equal to “INACTIVE”.

Tips:

For help, look at the “END THE CALL” section of example program 1 in section

“Example Programs”.
