This Instrument is design to demonstrate the method to transmit signals via. Electromagnetic transmission and to study the Phase Shift Keying Modulation and Demodulation. Whole instrument is placed in plastic moulded box and 2 mm banana plug leads are provided for modulation and demodulation connections.
1. Fixed Output DC Regulated Power Supplies of ±12 V and ±5 V.
2. Built in Carrier wave Generator (Sine Wave) of 5 Vpp, 22 KHz ± 5% Frequency range with output on sockets.
3. Built in Data Generator using IC 7490 with four modulating signal outputs on sockets.
4. IC TL084 & IC 7486 are using for PSK demodulator.
5. Circuit diagram is printed on the milky white top panel and important connections are brought out on the sockets.
