Bird Dog 3
Geophone Testing – Hydrophone Testing – Vibrator Testing
Versatile Quality Control System – Three Test Units in One!
General Purpose QC Tool:
32-bit, high speed, ADC chip for lower noise and increased accuracy
Three different operation with a single unit
8 Gigabytes of Data Storage, Expandable to 16
GPS based time and location saved for every record
Stable and rugged unit for use in all conditions
Three-Component Test Mode, checks 3 elements at once
to save time and effort
All test data saved in non-volatile memory for later download and retrieval
Connects to PC via Ethernet or optional Wi-Fi, provides control, data download and real time display
and analysis of data and results
Operation Modes:
Geophone Tests: QC individual element or strings of geophones – Measures Resistance, Impedance, Sensitivity, Distortion, Polarity, Damping Frequency and Leakage, verifies polarity and performance
Hydrophone Tests: QC individual hydrophones or streamer sections – Measures electrical and acoustic properties, verifies accuracy and output
Vibrator Tests: QC vibrator performance in the field, using independent accelerometers – Includes amplitude and phase displays, force and distortion analysis, verifies correct ground force calculation and polarity
