Type 4281

DEMODULATION BOARD Type 4281

Type 4281 complements the modulation board Type 4280 with the most important demodulators. A built-in power supply, output sockets for additional devices and a loudspeaker make it a complete lab platform for reception and recovery experiments.

  • All important demodulators on one board
  • Extension for modulation board Type 4280
  • Short-circuit-proof built-in power supply
  • Additional sockets for other devices
  • Integrated loudspeaker for audio playback
  • Suitable for AM, FM, PM, PAM, PCM, PFM and PSK experiments

Demodulation functions

The board covers the usual demodulation methods for analogue and digital communication. AM, FM, PM, PAM, PCM, PFM and PSK can be investigated with the provided modules.

The integrated functional groups make it easy to follow the recovery of useful signals and the effect of filters, Schmitt triggers and PLL loops.

Lab operation

The board can be operated on a desk in an inclined position or mounted in a frame. An optional box is provided for transport and storage, and experiments can also be carried out directly in the box.

Separating measurement, supply and output points makes it easier to use the board together with the modulation board and other hps systems.
