Using the 82357A
Modes of Operation
Single 82357A Operation
When an 82357A is first installed and configured, a default VISA Interface
ID, SICL Interface ID, Logical Unit (LU) number and GPIB Address are
automatically assigned to the Serial Number associated with this specific
82357A.
For example, assume an 82357A with Serial Number US12345678. When
this 82357A is first installed, typical values as shown are automatically
assigned to this Serial Number.
„
VISA Interface ID: GPIB0
„
SICL Interface ID: hpib7
„
Logical Unit: 7
„
GPIB Address: 21
For single mode of operation , when the existing 82357A is removed and a
new 82357A is installed, the new 82357A assumes all configuration
attributes of the previously configured 82357A (same VISA Interface ID,
SICL Interface ID, LU and GPIB Address). Thus, any SICL/VISA
applications using that VISA/SICL configuration will continue to run using
the new 82357A.
The first time an 82357A is attached to a system (assuming the Agilent IO
Libraries Suite is installed), the software recognizes that an 82357A is
attached. If Connection Expert is not running, the software displays an
Agilent 82357A USB/GPIB Interface Detected
dialog box that allows you to
accept the current settings. If Connection Expert is running, it automatically
refreshes, displaying the 82357A as a USB/GPIB interface in its tree view;
you can then change the properties of the interface in Connection Expert.
The VISA and SICL interface IDs, Logical Unit, and GPIB Address may be
viewed at any time in the
property pane
of the Connection Expert. (To view
this window, click the blue IO icon and then click
Agilent Connection Expert
.)
Then, if you disconnect this 82357A and plug in another 82357A (with a
different Serial Number) or if you re-plug the same 82357A, the new 82357A
will assume the same VISA Interface ID, SICL Interface ID, LU, and GPIB
Address as the original 82357A.
NOTE
You can change the parameter values of the 82357A as required.
See “Changing Configuration Parameters” for details.
