N2260A 40-Channel MUX Module
The Agilent N2260A is a configurable multiplexer (MUX) module. It
contains 40 2-wire latching relays for switching, and two non-latching
tree relays for configuration.
The N2260A can be configured as:
•
an 80-channel 1-wire multiplexer,
•
a 40-channel 2-wire multiplexer (default),
•
two independent, 20-channel 2-wire multiplexers, 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 N2260A to its default
configuration (as a 40-channel 2-wire MUX module).
The N2260A can be operated in either SCPI mode or 3488A mode, but
configuration is only possible in the SCPI mode. In 3488A mode, the
N2260A can only be used as a 40-channel 2-wire MUX module.
A parallel switching feature makes the N2260A well suited for high
speed switching. The 40 2-wire relays on the N2260A 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 N2260A are given on page 303.
