Appendix C
Instrument Interference
Immunity regulations place the onus on instrument/apparatus/device manufacturers to assure
that extraneous interference will not unduly cause an instrument/apparatus/device to stop func-
tioning or to function in a faulty manner.
that extraneous interference will not unduly cause an instrument/apparatus/device to stop func-
tioning or to function in a faulty manner.
Based on independent testing house measurements, Sensors & Software Inc. systems comply
with such regulations in Canada, USA, European Community and most other jurisdictions. GPR
devices can sense electromagnetic fields. External sources of electromagnetic fields such as TV
stations, radio stations and cell phones, can cause signals detectable by a GPR which may
degrade the quality of the data that a GPR device records and displays.

Such interference is unavoidable but sensible survey practice and operation by an experienced
GPR practitioner can minimize such problems. In some geographic areas emissions from exter-
nal sources may be so large as to preclude useful measurements. Such conditions are readily
recognized and accepted by the professional geophysical community as a fundamental limitation
of geophysical survey practice. Such interference being present in the GPR recordings is not
considered as an equipment fault or as a failure to comply with immunity regulations.
