PSK/QAM/APSK Digital Modulator

KEY FEATURES

Digital modulator with flexible configuration:

Modulation: BPSK, QPSK, OQPSK, p/4 DQPSK, 8-PSK, 16QAM, 16APSK, 32APSK
Variable data rates up to 22 Msymbols/s
Center frequency: +/- 10 MHz

Modulator outputs:

Digital (2 * 10-bit complex, up to 90 Msamples/s)
Digital (2 * 14-bit complex, up to 50 Msamples/s)

Modulator data inputs:

Synchronous serial interface, or
USB 1.1/2.0

Internal generation of pseudo-random bit stream and unmodulated carrier for test purposes

Synchronization sequence (unique word) insertion to facilitate demodulator phase ambiguity removal

ComScope-enabled: key internal signals can be captured in real-time and displayed on the host computer

Connectorized 3"x 3" module for ease of prototyping. Standard 40 pin 2mm dual row connectors (left, right, bottom). Single 5V supply with reverse voltage and overvoltage protection. Interfaces with 3.3V LVTTL logic
