HP-IB Chec Example lrogram 1

This first program is to verify that the HP-IB connections and interface are functional. Connect a controller to the synthesizer via an HP-IB cable. Clear and reset the controller and type in the following program:

10Source=719

20ABORT 7

30LOCAL Source

40CLEAR Source

50REMOTE Source

60CLS

70PRINT "The source should now be in REMOTE."

80PRINT "Verify that the 'REMOTE' LED is on."

90END

Run the program and verify that the REMOTE LED is lit on the synthesizer. If it is not, verify that the synthesizer address is set to 19 and that the interface cable is properly connected.

If the controller display indicates an error message, it is possible that the program was entered in incorrectly. If the controller accepts the REMOTE statement but the synthesizer REMOTE LED does not turn on, perform the operational checks as outlined in the respective Operating and Service Manuals to find the defective device.
