The ZT-30B is a transmitter capable of producing time-domain or frequency-domain waveforms into either resistive or inductive loads. As a TEM transmitter, the ZT-30B can deliver up to 30A into a 100m loop with a turnoff time of less than 200 µs. Because the ZT-30B also performs well while transmitting into resistive loads, some customers can use it as a low-power resistivity transmitter.
