•
The term "Multiplexer" is used in this manual to refer to the
HP E1476A 64-Channel, 3-Wire Multiplexer Module.
•
The HP E1476A is a VXIbus C-size register-based slave device. The
Multiplexer can operate in a C-size VXIbus mainframe or a VMEbus
mainframe.
•
The Multiplexer "instrument" is the firmware running in the
Upcoming Module (HP E1406A, for example). This firmware is the
instrument driver providing SCPI (Standard Commands for
Programmable Instruments) programming capability. The term
"switchbox" is used to refer to an "instrument" made up of one or
more switch modules.
•
Programming the HP E1476A can either be through the command
module using SCPI commands (see Chapter 3), through an embedded
controller using Compiled SCPI (C-SCPI, see the HP catalog for
details on this product) or Standard Instrument Control Language
(SICL) or via direct register access (register-based programming - see
Appendix B).
•
Reed relays are used for each channel and tree relay.
•
Maximum voltage is 120VDC/RMS or 170V peak.
•
Maximum current is 35mA (non-inductive).
