The board consists of FSK (Frequency Shift Keying) modulator and demodulator sections that can be interconnected in order to simulate a complete transmission system.

Technical features
The board uses the DL 2560B board as a service module to provide the carrier signal, the modulating random digital signal, the error rate meter and the line simulator.
FSK modulator and PLL demodulator.
Power supply: ± 15 Vdc, 50 mA

The board consists of ASK (Amplitude Shift Keying) modulator and demodulator sections that can be interconnected in order to simulate a complete transmission system.

It contains:

• clock and carrier generator obtained from a single quartz source at 2.4576 MHz with clock frequency selectable among 2400, 4800, 9600, 19200 and 38400 Hz
• pseudo-random data generator that generates two random sequences of 1 and 0 of different length, 15 bits and 255 bits
• BER meter
• artificial noise generator at an adjustable level that generates a signal with quasi-white spectrum in the 2 - 40 kHz band
• jitter meter

The board allows the study of base band transmission techniques with different types of coding: RZ (Return to Zero), NRZ (Not Return to Zero), Manchester, Biphase and Duo-binary.
