VIB PRO™ HD
FEATURES • Backwards-compatible with existing Vib Pro controllers • Provides accurate and versatile sweep generation across all surface terrains ensuring delivery of the desired energy • Increased computing power improves control resolution and force accuracy • Optimized low and high frequency control for INOVA’s vibroseis vehicles • Low frequency limit control reduces risk of damage to vibrator mass assembly • Supports INOVA’s patented Harmonic Distortion Reduction (HDR) technology • Integrated wired and wireless Ethernet communication • Integrated VSS and PSS data management and storage • Dynamic TDMA, collision-free radio communications • Analog and digital radio* support • Compatible with most acquisition systems and p-wave vibroseis vehicles on the market • Units can be easily programmed as an encoder* or decoder • Low ground force mode for environmentally-sensitive areas
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 HD 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 improves the linearity and bandwidth of the vibrator’s servo-valve • HDR technology is available on all new Vib Pro HD controllers and is also available as a simple, in-field upgrade to existing Vib Pro units
