Using the Agilent 82357B 2
82357B User’s Guide 19
Introduction to 82357B operating modes
The 82357B has two modes of operation. When only one
82357B is connected to a USB port within a system, we
define the feature as the
Single Mode Features . When up to
four 82357Bs are connected at the same time to USB ports
within a system, we define the feature as the
Multiple Mode
Features .
Single Mode Features
For single mode operation, the operating parameters (VISA
Interface ID, SICL Interface ID, Logical Unit Number, and
GPIB Address) are set when the 82357B is first installed.
If this 82357B is unplugged and replugged, or if the 82357B
is replaced with a different 82357B, the previous
configuration parameters are automatically assigned to the
newly attached 82357B. Thus, you can exchange 82357Bs at
any time without reconfiguring the interface. This allows
exchanging 82357Bs among users, as long as only one
82357B is attached at any one time.
Multiple Mode Features
In contrast, when up to four 82357Bs are connected to the
system at the same time, each 82357B must have its own
specific set of operating parameters and each 82357B serial
number is “bound” to its operating parameters. In multiple
mode operation, if you add a new 82357B or if you unplug
an 82357B and plug in a new 82357B in its place, the newly
installed 82357B, will be assigned a new (unique) set of
operating parameters.
N O T E
All SICL/VISA applications are notified when their 82357B has been
removed from the system by returning
VI_ERR_NOINFC (for VISA) or
I_ERR_NCIC (for SICL).
