N2266A 40-Channel MUX Module
The Agilent N2266A is a configurable multiplexer (MUX) module. It
contains 40 2-wire non-latching relays for switching and two non-
latching tree relays for configuration applications.
The N2266A can be configured as:
•
an 80-channel 1-wire multiplexer,
•
a 40-channel 2-wire multiplexer (default),
•
two independent 20-channel 2-wire multiplexer,
•
or a 20-channel 4-wire multiplexer.
These modes can be selected from the front-panel or with a SCPI
command (see page 83).
An instrument power-on or reset will set the N2266A to its default
configuration as a 40-channel 2-wire MUX module. When instrument
power is removed, all relays will open on the multiplexer.
The N2266A can be operated in either SCPI mode or 3488A mode, but
configuration is only possible in the SCPI mode. In 3488A mode, the
N2266A can only be used as a 40-channel 2-wire MUX module.
A parallel switching feature makes the N2266A well suited for high
speed switching. The 40 2-wire relays on the N2266A can be separated
into four groups and up to 10 relays in the same group can be closed
simultaneously (parallel switching). The groups are: group 1 (channel 00
through channel 09), group 2 (channel 10 through channel 19), group 3
(channel 20 through channel 29) and group 4 (channel 30 through
channel 39). Additional information about parallel switching is given on
page 84.
Specifications for the N2266A are given on page 315.
