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.
