82357A Specifications
Supplementary Information
Supplementary Information
This section provides supplementary information on the 82357A
performance, including supported GPIB modes.The 82357A is defined as a
controller as it can be (and is required to be) the system controller.
GPIB Modes of
Operation
Supported
The 82357A supports standard GPIB modes of operation, except for:
„ Parallel Poll (PPOLL)
„ Passing of Active Controller
„ Non-System Controller mode, which prevents using SICL
Commander sessions or VISA Servant sessions
IEEE-488.1 and
IEEE-488.2
Compliance
The 82357A is in full compliance with IEEE 488.1 and IEEE-488.2
specifications. The 82357A fully supports IEEE-488.1 subsets AH1,
C1, C2, C3, C4, C27, DC0, DT0, LE3, PP0, RL0, SH1, SR0, and TE7.
SRQ Response
Time
SRQ response time is slower than with the 82350 PCI GPIB interface as an
artifact of the USB implementation. In addition, sharing the USB bus with
other devices may impact GPIB performance.
Default T1 Delay
The default T1 delay for the 82357A is 800 nsec. See “Setting 82357A
High-Performance Operation” in Chapter 2 - Using the 82357A for details.
Maximum 82357A
System
Configuration
Up to four 82357As on a system have been successfully tested.
