Supported remote interfaces
The Model 2657A supports the following remote interfaces:
•
GPIB. General purpose interface bus is an IEEE-488 instrumentation data bus.
•
LAN. Local area network (LAN) communications provide the flexibility to build scalable and
functional test or data acquisition systems with a large degree of flexibility.
•
RS-232
The Model 2657A can only be controlled from one communication interface at a time. The first
interface on which it receives a message takes control of the instrument. It ignores the other
interfaces until the instrument is returned to local operation.
For more information about the remote interfaces, see:

Output queue
Response messages, such as those generated from print commands, are placed in the output queue.
All remote command interfaces share the same output queue.
The output queue sets the message available (MAV) bit in the status model.
The data in the output queue is cleared by the
*CLS
command.
