VIB PRO™
FEATURES
•
Provides accurate and versatile sweep generation across all
surface terrains ensuring delivery of the desired energy
•
Supports stored value custom sweeps and offers 16 standard
keyboard sweeps with up to 16 different segments for each sweep
•
Integrated Ethernet communication port
•
Redundant storage of QC and shot data
•
Digital-coded transmission provides error detection and
correction for reliable communications
•
Compatible with most acquisition systems and p-wave vibroseis
vehicles on the market
•
Units can be easily programmed as an encoder or decoder
TECHNICAL SPECIFICATIONS
•
Encoder is compatible with other INOVA controllers enabling quick
Power Input:
and easy transition between vibroseis and dynamite operations
Voltage Input:
•
Master/slave functions in Vib Pro encoders allow multiple recorder
configurations and data repeater option for operations in poor
radio transmission areas
•
Vib Pro provides low ground force mode for environmentallysensitive areas
•
Stable control of servo-valve at high frequencies
•
Optional integrated GPS
HDR TECHNOLOGY ADVANTAGE
™
•
Patented Harmonic Distortion Reduction (HDR) technology
provides better vibrator control generating more fundamental
force at the low end of the frequency spectrum in any environment
using nonlinear compensating control algorithms
•
HDR Technology reduces harmonic distortions and results in
improved signal-to-noise ratios
•
HDR Technology is included in the Vib Pro firmware to compensate
for the nonlinear behavior of the main-stage servovalve
•
When utilized with the DR Valve, HDR Technology is further
optimized by dampening the earth/baseplate resonance and
