point2point unit and battery

point2point  Fibre Links

point2point links are fixed gain, analogue signal transmission systems – solving electrical interference and signal attenuation problems in signal monitoring and distribution. Depending on frequency range, point2point links use either intensity or 14-bit digital modulation to convert analogue signals for transmission over fibre.

Prodyn D-DOT A-100 electric field sensor

Electric Field Sensors

D-dot electric field sensors are small to medium sized high frequency sensors that measure the rate of change over time in electric displacement. The Prodyn sensors are available in two types:

  • Free-field
  • Ground plane.

Prodyn BIB series balun

Baluns and Transformers

PPM Test supplies high voltage, wide-band baluns manufactured by Prodyn. These high frequency baluns are designed to convert the differential outputs from free-field sensors to a single ended 50 Ω output for capture on a recording or measuring device. Transformers are also available in several configurations for different applications.
