Introduction To 82357B Operating Modes - Keysight 82357B User Manual

Using the Keysight 82357B 2

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.
All SICL/VISA applications are notified when their 82357B has been removed
NOTE
from the system by returning VI_ERR_NOINFC (for VISA) or I_ERR_NCIC (for
SICL).
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.
