M221
8 Channel
Form C Switch
M Module

The M221 (formerly Agilent
E2273A) provides 8 independent
non-latching SPDT switches with
maskable interrupts that occur when
the requested relay movements
have been made. This M Module is
useful when high integrity contacts
are needed driving microwave
relays located in your test adapter.
