Powerful software function----sampling software under WINDOWS supports all kinds data acquisition of seismic methods (shallow reflection, refraction, secondary wave speed testing, micro-seismic survey, high density image and other application). Data displaying and rolling screen are very quick by using advanced graphic technique. Channel on the screen is adjustable, 128 channel maximum.

Industrial PC configuration----PIII 533MHz, 128M memory, 40G harddisk, interior CD-ROM, 800 600TFT true color LCD, Chinese character tablet, small keyboard, photoelectric mouse, 32M Flash-Memory, double serial port, one parallel port, double USB port, mouse port, keyboard port. Seismic data collecting and transacting is convenient.

Configuration and expansibility----DOS or WINDOWS software available. Instrument can be upgraded to 48 channel seismograph by purchasing data collecting card and software

Stack survey support----Combined with our WZKD-1 electric stack switcher, stack survey can be realized efficiently.

Reasonable configuration---- anti-shake, damp-proof and dust-proof design.

4. Feature:

Fast sampling----true 24-bit A/D, minimum sampling interval: 50μs for 24 channel.

Rendering original signal perfectly----perfect amplitude and phase consistency, low distortion, band outside shearing better than 72dB (shearing frequency point changing with sampling frequency automatically, removing alias completely).

High-speed data transfer----Transmitting data by USB port between internal industrial PC and data collector. Advanced hardware make the sampling and transferring data simultaneously.
