Description
The turn-off of the transmitter, as well as the sample rate of the receiver, is a critical component in the ability of a TEM system to image the shallow electrical section. The length of the turn-off acts as a filter on the decay and can remove the response of thin layers.
Turn-off of the NT-20 into a 20m x 20m loop is approximately 1 microsecond. When coupled with high-speed sampling from the GDP-3224, the NT-20 is a unique tool for shallow groundwater applications with resolution in the upper 2-3 meters.
