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.

Specifications:
Implementation:
• All versions use either two (2), four (4) or eight (8)
ANSI/VITA Standard 16 Channel M-Modules
(MA203), each of which have the block diagram
shown above
• See the EM405D and EM405-8 on C&H web site for
further information on the instrument enclosure
mounting and dimensions.
Trigger/Sample Strobe Features:
• An external clock may be routed through one
mezzanine to a carrier trigger and back to the Event
Detector triggers to minimize skew between
channels
• One mezzanine’s clock may be used as a master in
a similar manner
External Trigger Inputs:
• 32 Channel Unit TTL
• 64 & 128 Channel Units TTL and LVDS
External Power (32 Channel Unit):
• AC Input 100 to 240VAC, 47 to 63Hz with furnished
adapter
• Alternatively DC powered by 12V, 1A
External Power (64 and 128 Channel Units):
• AC Input 85 to 265VAC, 47 to 63Hz
• Alternatively DC Powered by 36 to 75V
Software Driver:
• Windows DLL
• Soft Front Panel Executable
• Online Help
• LabWindows/CVI Function Panels
• ANSI-C Source Code
• LabView
Conformance:
• These modules will be CE compliant for Emissions,
Immunity and Safety
