CMG-DM16
The input stages of all the differential amplifiers are protected
against excessive input voltages and limited to ±10V.. Each
input is furnished with an inductor and capacitor network to
filter out the high frequency signals and enable a minimum of
100dB of common mode rejection.
To minimise ground loops the differential power supply is
isolated. Two sets of dedicated dc-dc converters ensure low
noise dc supply voltages to the input stages and the digitizer
electronics.

Güralp Systems also manufacture a 16-channel DM16 unit, the
DM16R16. This is a 2U rack-mount module containing two 8-
channel digitizers with cascaded output. A single GPS unit can
synchronize both digitizers to the same time base.
The DM16R16 can optionally be supplied with an internal CMG-
DCM data communications module. The DCM is a low-power
network device running a full Linux operating system, providing
a cost-effective way to connect multiple analogue data sources
to a modern TCP/IP network. The DM16R16DCM also fits within
a 2U rack space.
