DIGITAL EXPLORATION SEISMOGRAPH 24 BIT PASI MOD. ANTEO

Product catalog summary

Overview: The PASI MOD. ANTEO is a modular exploration seismograph system designed for geophysical applications. It features a scalable architecture allowing for an unlimited number of channels, making it adaptable to various seismic exploration needs.

Main Technical Features:

Modular system with unlimited channels.
24-bit A/D conversion at each geophone ensures high signal quality.
8” SVGA display with LED backlight for clear data visualization.
Operates on a Linux system, providing robust performance.
Geophone testing capabilities include impedance, frequency, dumping, electric noise, and circuit checks.
Record length of 25,000 samples, with customizable options available.
Sampling interval ranges from 0.016 to 62.5 ms across all channels.

Applications:

Seismic refraction and reflection studies.
S-wave analysis including MASW, Re.Mi., Vs30, HVSR, etc.
Down-hole and cross-hole seismic surveys.

System Design: The ANTEO system is built around a central control unit (ANTEO CU) that interfaces with multiple AD6-x cables, each equipped with 24-bit A/D converters. This setup allows for easy expansion from 6 channels to any desired number by adding more cables. The digital signal is processed directly at the geophone, ensuring optimal signal-to-noise ratio regardless of cable length or environmental conditions.

User Interface and Functionality: The ANTEO CU can be connected at any point along the cable spread, automatically recognizing and testing all connected geophones. It includes a real-time noise monitor and a roll-a-long function for efficient data acquisition.

Technical Specifications:

Dynamic range: 144 dB system, 118 dB instantaneous.
Input impedance: 100 kOhm//22nF.
Distortion: 0.001% at 2 ms.
Frequency response: up to 30 kHz at 64 KS/s.
Various filter options including low pass, high pass, and notch filters.
Power supply: 12VDC external battery.
Operating temperature: -30°C to +80°C.
Data format: SEG-2, with other formats available on request.
Trigger options include contact closure, analog signal, and TTL triggering.
Optional connectivity features: Ethernet, Wi-Fi, Bluetooth, GPS, etc.

Physical Characteristics: The ANTEO CU is compact and lightweight, with dimensions of 339mm x 295mm x 152mm and a weight of less than 3 kg.

DIGITAL EXPLORATION SEISMOGRAPH 24 BIT PASI MOD. ANTEO-2

EXPLORATION SEISMOGRAPH PASI MOD. ANTEO www.pasigeophysics.com ANTEO is the expression of a new philosophy for a modular exploration seismograph. The system consists of a single control & display unit (ANTEO CU) that works together one or more special cables (ANTEO AD6-x), each one with no.6x 24 bits A/D converters to be connected to any standard analogue geophone. This means that your system can grow from 6 to any number of channels with the simple addition of more AD6-x cables, available with different geophone spacing (5m & 10m standard spacing, others on request) according to your own requirements....
