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.
