5-1. Introduction
Note
Unless otherwise stated, the use of “6100B” in this manual refers to the entire
product family of 6100B and 6105A Master units, and 6101B and 6106A
Auxiliary units.
The 6100B and 6105A Electrical Power Standards are capable of operating under the
remote control of an instrument controller, computer or terminal, as well as under the direct
control from the front panel.
The Auxiliary units can also be controlled remotely. But, in this case the remote control
connection is still made to the 6100B, which in turn communicates with the Auxiliary units.
XWWarning
The Instrument is capable of supplying lethal voltages. Do not
make or touch connections to the output binding posts while the
Instrument is connected to the GPIB to avoid unexpected,
dangerous settings.
5-2. Using the IEEE-488 Port for Remote Control
The 6100B is fully programmable for use on the IEEE Standard 488.1 interface bus
(IEEE-488 bus). The interface is also designed in compliance with supplemental standard
IEEE-488.2. Devices connected to the bus in a system are designated as talkers, listeners,
talker/listeners, or controllers. Under the remote control of an instrument controller, the
6100B operates exclusively as a talker/listener on the IEEE-488 bus.
For more detailed information, refer to the standard specification in the publications ANSI/
IEEE Std. 488.1 - 1987 and IEEE Std. 488.2 - 1988.
The Instrument conforms to the Standard Specification IEEE 488.1 - 1987: “IEEE Standard
Digital Interface for Programmable Instrumentation”, and to IEEE 488.2 - 1988: “Codes,
Formats, Protocols and Common Commands”.
In IEEE 488.2 terminology the 6100B is a device containing a system interface. It can be
connected to a system via its system bus and set into programmed communication with
other bus-connected devices under the direction of a system controller.
5-3. Programming Options
The Instrument can be programmed via the IEEE Interface, to:
• Change its operating state (Function, Source, etc).
• Transmit its own status data over the bus.
• Request service from the system controller.
5-4. Capability Codes
• To conform to the IEEE 488.1 standard specification, it is not essential for a device to
encompass the full range of bus capabilities.
• For IEEE 488.2, the device must conform exactly to a specific subset of IEEE 488.1,
with a minimal choice of optional capabilities.
The IEEE 488.1 document describes and codes the standard bus features, for manufacturers
to give brief coded descriptions of their own interfaces’ overall capability.
For IEEE 488.2, this description is required to be part of the device documentation. A code
string is often printed on the product itself.
