Transmitter IP-1000M is designed to produce bipolar rectangular current pulses under the load while induced polarization or electrical resistivity method is performed.
TEM-200 transmitter generates periodic bipolar rectangular current pulses with pauses (50 % duty cycle) in an inductive load (loop) as a source of primary magnetic field in TEM method.
Electrical exploration transmitter ASTRA-100 is designed to produce electromagnetic field during geophysical survey using currents with frequencies from 0.063 to 2500 Hz. Maximum output current peak power of 100 W allows depths of investigation from first meters up to first hundreds of meters to be reached.
ERG-120 can be used both in time-domain mode (bipolar rectangular current with 50 % duty cycle) or frequency-domain (square wave).
