Antenna, Loop Sensor
EM-6873 | 20 Hz – 100 KHz
-
The EM-6873 Loop Sensor Antenna uses passive circuits to transform magnetic field components between 20 Hz – 100 kHz to an equivalent open circuit two-terminal voltage on the receiving instrument. Use of the conversion Factor Chart, supplied with each antenna, will yield the strength of the magnetic induction field referenced to a uniform field. The loop is electrostatically shielded and therefore is sensitive only to the magnetic component (B-field) of the electromagnetic fields.

Dual Channel HV Amplifier with Phase Inverter
A400DI
-
This unit contains two independent A400 amplifiers that share common ground reference and power supply. Please see A400 page for technical details.It features also a low voltage phase inverter that inverts the signal applied to the input of channel 1. The resulting signal can then be connected to the input of channel 2 by means of a short BNC cable (supplied). As a result the two outputs operate in counter-phase. Connecting a load between the outputs effectively doubles the amplitude range. Please note that the load cannot have any connection to ground.
