GPIB (IEEE-488) Bus Verification
Use the GPIB Controller and the Model 4500B to perform basic operations.
1. Connect the GPIB controller and the 4500B with a GPIB cable.
2. Press the Init system key and Init > Defaults > LOAD to put the 4500B in a known state.
3. Set the 4500B to use the SCPI language mode (instead of the 4500A emulation mode)
with the Util > Remote Conf > GPIB > Emulate 4500A > OFF menu selection.
4. Set the 4500B‘s GPIB address using the Util > Remote Conf > GPIB > Bus Setup >
Address # menu. Choose a convenient number between 1 and 30 that will be unique to
the test instrument.
5. Press the CLR key to clear any pending errors.
6. Using the GPIB controller, send the command *IDN? to the Model 4500B. The REM
message should appear in the lower right display rectangle indicating that the Model
4500B is in the ―remote‖ mode; the LSN message should appear when the command is
sent, indicating that the Model 4500B is ―listen addressed.‖ No error messages should
appear on the display.
7. Use the GPIB controller to read a string from the 4500B. A string similar to the
following should be returned:
Boonton Electronics,4500B,103,ver20051007
The string contains the manufacturer‘s name, the model number, serial number and
software version number. The TLK message should appear indicating that the Model
4500B is in the talk mode.
8. Using the GPIB controller, send the command SYSTem:ERRor? The lower case letters
are optional. Use the GPIB controller to read a string from the 4500B. The following
should be received:
0, "No Error"
If there were an error, a non-zero code number and a short message would be received.
9. Press the Local system key. The REM message should disappear. If it does not, the GPIB
controller may have sent the ―Local Lockout‖ command. If this is the case, send the ―Go
To Local‖ command from the controller and the REM message will disappear.
