Capability Commands
To conform to the IEEE 488.1 standard specification, it is not essential for a device to
encompass the full range of bus capabilities. The IEEE 488.1 document describes and
codes the standard bus features, so that manufacturers may give brief coded descriptions
of their own interfaces’ overall capability.
The codes that apply to the Meter are given in Table 1 below, together with short
descriptions. These codes conform to IEEE 488.2 requirements.
Appendix C of the IEEE 488.1 document contains a complete description of each code.
Table 2. IEEE 488 Compatibility Codes
IEEE 488 Subset Interface Functions
SH1 Source Handshake Capability
AH1 Acceptor Handshake Capability
T5 Talker (basic talker, serial poll, unaddressed to talk if addressed to listen)
L4 Listener (basic listener, unaddressed to listen if addressed to talk)
SR1 Service Request Capability
RL1 Remote/Local Capability (includes local lockout)
PP0 No Parallel Poll Capability
DC1 Device Clear Capability
DT1 Device Trigger – Supports group trigger (GET).
C0 No Controller Capability
E2 Open-Collector and Three-State Drivers
Interconnections
Instruments fitted with an IEEE 488 interface communicate with each other through a
standard set of interconnecting cables, as specified in the IEEE 488.1 Standard
document.
The IEEE 488 interface connector is located on the Meter’s rear panel.
