CMG-DM24S12AMS Operator's guide
1.1 Feature overview
•
A built-in Digital Signal Processor (Motorola 56002) provides
simultaneous multiple sample rate data streams at user selectable
rates. Up to 4 streams of data for each component are available at
sample rates from 1 to 200 samples/s.
•
A precision microprocessor-controlled time base synchronizes
Analogue to Digital Converters, and DSP and time-stamps data
blocks.
•
Time synchronization to external GPS or serial time code.
•
A control microprocessor (Hitachi H8) formats and buffers data
in an on-board 512k RAM ring buffer.
•
Efficient data storage and transmission using the Güralp
Compressed Format.
•
Serial data output (RS232) at user selectable baud rates—options
of RS422, DPSK or fibre-optic.
•
Built-in microprocessor system configuration and sensor control,
including locking and unlocking, centring and calibration.
•
Low system power consumption, less than 3W (excluding the
integrated PC)
•
Flash EEPROM for program code and filter coefficients.
