Certificate
To Whom it may concern:
This is to certify that electromagnetic radiation emissions from transducers (antenna with
transmitting and receiving electronics) manufactured by Geophysical Survey Systems, Inc.
(GSSI) DO NOT constitute a safety or health hazard to operating personnel.
Emissions from GSSI transducers are below the 10mW/cm² (100W/m²) level specified by the
United States Occupational Safety and Health Administration (OSHA) regulations
Paragraph 1910.97 states:
"For normal environmental conditions and for incident electromagnetic frequencies from
100 MHz to 100 GHz, the radiation protection guide is
10 mW/cm² (milliwatt per square centimeter) as averaged over any possible 0.1 hour
period."
Emissions data using GPR SIR System-10, SIR-2, SIR-3, SIR-4, SIR-8, SIR-20, SIR-2000 and
SIR-3000 (at the standard Pulse Repetition Frequency of 100 KHz) with the antenna Models
listed and levels of Electromagnetic Radiation are specified herein:
Following is the average power density data at 5cm and wide band.

Signal Position
Place the antenna on the ground and use the Automatic Signal Position selection. The system
will servo and place the direct coupling pulse at the top of the time range window.
To test that you have the correct position, raise the antenna off the ground and you will observe
on your system that the antenna transmit pulse will separate from the reflection from the ground.
The higher that you raise the antenna, the further apart will be the two pulses.
To assure that the direct coupling pulse (time zero) is recorded the user should place the signal
Position servo in the manual mode. The signal should then be moved down in the time range
window until the entire surface pulse is visible and there is some ‘dead time’ or flat trace visible
above the direct coupling pulse in the time range window.
Gain Check
The surface pulse should be about 2/3 the width of the screen. If it is greater, reduce the Gains
manually. If the signal appears too small you can manually increase the Gains, but the first gain
point should never exceed 10dB, the last gain point should not exceed 65dB.
