Instruments
The EM405D100, EM405-8x106
and EM405-8x107 are 32, 64, and
128 channel input modules that
sample and selectively store up to
128 bits of data along with a 31 bit
time tag at rates up to 5 MSPS.
These instruments have the ability
to store all data at the specified
sample rate or to selectively store
input values based upon changes in
state on one or more of the inputs.
Each version is 1U high with the 32
channel unit designed for bench
applications and the 64 and 128
channel version for rack mounting.
