Performance Verification
Verifying the Multiple Channel Controller
Verifying the Multiple Channel Controller
This portion of the verification will check the 85330 multiple channel switch
controller to ensure that it is operating correctly. It will also check the
Switch Control Unit of the Agilent 85331/2 to make sure that it is switching
correctly. Document the test results by plotting or printing the test
instrument screens as each test is performed.
Turn-On Turn the multiple channel controller ON; the following screen should
appear:

SYSTEM 85330A IBASIC (see note below)
NOTE IBASIC is only present if the IBASIC option is installed.
If you see the above display, the unit has passed its turn on tests and is
working properly. If you do not see this display, load the 85330A
downloadable driver files as explained in the
“Loading the Driver from a
Personal Computer” on page 1-6 .
Voltage Check Check the voltage on the switch control unit’s OUTPUT connector. This is
the connector that is used to daisy-chain the switch control units together.
The voltages are shown in
Table 2-2 . If an external power supply is used to
bias the switch control units, the supply may require some adjustment to
keep the voltage within the tolerances.
