82357A Specifications

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.
