This provides for the independence of probe orientation relative to the polarization of the field. The instantaneous charge distribution on adjacent cold junction elements produces a potential difference across the
The Model 8764D operates from 100 kHz to 300 MHz. It contains three orthogonal displacement energy sensors with diode detectors. This unique design has much lower impedance than traditional dipole designs. The major advantage is the greatly reduced interaction between the meter and probe, the human body making the measurements, and the RF field.
The Model 8782D uses an “active antenna” design to accurately measure RF fields as low as 3 kHz over a 60dB dynamic range.
These probes are responsive to the
