Type 4283
RECEIVER BOARD Type 4283
Type 4283 is the receiver section of the transmission system for fibre optics, infrared and wired-line experiments. Optical and electrical input signals can be evaluated with adjustable amplifiers and output stages. This makes the transmission behaviour easy to analyse directly.
- Receiver board for fibre optics, infrared and lines
- Optical input for plastic and glass fibre
- Electrical input for two-wire and coaxial line
- Amplifier with adjustable gain
- DC and AC outputs plus TTL output
- Schmitt trigger for digital signals
Receiver side
The board represents the receiving side of the system. An optical input, an electrical comparison input and multiple output types allow a detailed analysis of attenuation, waveform and level behaviour.
The adjustable coupling can be used to simulate attenuation on plastic fibres in a controlled way.
Lab applications
The receiver can be combined with the transmitter board Type 4282, the modulation board Type 4280 and the demodulation board Type 4281. This creates complete experimental chains for analogue and digital transmission paths.
Comparison measurements with two-wire and coaxial lines are also possible.
