2.1 OVERVIEW
The GDP-32II Geophysical Data Processor is a universal, multi-channel receiver designed to
acquire virtually any type of electromagnetic or electrical data within the DC to 8 kHz
bandwidth. The GDP-32II design is the result of over 25 years experience with its predecessors,
the GDP-12, GDP-16 and GDP-32. Its design emphasizes software flexibility, optimum data
quality, practicality and ruggedness for harsh field conditions.
The GDP-32II is supported by a complete set of geophysical services at Zonge Engineering.
These services include:
Equipment sales and rentals
Geophysical consulting and training
Turn-key data processing
Custom Modeling and Processing Software
Contract field surveys
DESCRIPTION OF THE GDP-32II RECEIVER
Section 2, Page 3 May 2002
2.2 SPECIFICATIONS
The GDP-32II is designed for high quality data acquisition in harsh environments. Measurable
parameters include:
Resistivity
Induced Polarization (frequency or time domain)
Complex Resistivity (CR)
Controlled Source Audio Frequency Magnetotellurics (CSAMT)
Harmonic CSAMT (HACSAMT)
Frequency Domain EM (FEM)
Transient EM (TEM)
NanoTEM (a very early time TEM program)
Continuous NanoTEM
Natural Source MT
Natural Source AMT
Programs are stored on an internal flash disk and are software-selectable. Users can also develop
custom survey applications using the C programming language. However, this is a complicated
undertaking and should only be attempted with assistance from Zonge Engineering.
The GDP-32II operates in both the Frequency Domain and Time Domain. Twenty six (26)
frequencies can be selected in binary intervals between 0.000121 Hz and 8 kHz.
The GDP-32II is designed for multi-channel data acquisition. The large case GDP-32II can
accommodate up to sixteen channels for simultaneous measurements from DC to 8 kHz.
Multiple receivers can also be used together for n-channel acquisition.
The small case GDP-32IIT accepts a maximum of 6 analog channels. These channels can be a
mixture of high-speed NanoTEM acquisition boards (BD194) and the standard analog boards
(BD183). In either case, a maximum of 3 high-speed NanoTEM channels can be installed.
