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.
