Functional
Verification
Test
The Functional Verification Test for the Agilent E1351A, E1352A,
E1353A, E1357A, and E1358A FET Multiplexers consists of sending the
*IDN? command and checking the response. This test can be used to verify
that the FET Multiplexer is connected properly and is responding to a basic
command.
Procedure 1. Verify that the FET Multiplexer is properly installed in the mainframe
2. Verify that the terminal block or test fixture is properly connected to
the Multiplexer
3. Verify that the mainframe has passed its power-on test
4. Send *IDN? to the FET Multiplexer (see example following)
5. The return should be as follows (revision number may vary):
HEWLETT-PACKARD,SWITCHBOX,0,A.07.00
NOTES
If the primary address setting, secondary address setting, or the interface
select code is set incorrectly, the FET Multiplexer will not respond. Verify
proper address selection before troubleshooting.
Example An example follows which uses an HP 9000 Series 300 computer with
BASIC and a FET Multiplexer address of 70914.
10 DIM A$[100]
20 OUTPUT 70914;"*IDN?" !Send the ID command
30 ENTER 70914;A$ !Get response
40 PRINT A$
50 END
