Home >   Product List > COM-1002    BPSK/QPSK/OQPSK MODULATOR          

Key Features

• BPSK/QPSK/OQPSK modulator.
• Programmable data rates up to 20 Mbps (QPSK) and 10 Mbps (BPSK) by steps of at most 3bps.
• Includes raised cosine square root filter with 20%, 25%, or 40% rolloff options.
• Differential and non-differential encoding.
• Synchronization sequence (unique word) insertion to facilitate demodulator acquisition.
• Internal generation of pseudo-random bit stream and unmodulated carrier for test purposes.
• Built-in channel impairments generation:
    - frequency offset (Doppler)
• On-board or external clock selection.
• Single 5V supply
• Connectorized 3”x 3” module for ease of prototyping. Standard 40 pin 2mm dual row connectors (left, right, bottom). Interfaces with 5V and 3.3V logic.
• Note: the COM-1402 now provides higher performance (22 MSymbols/s, 90MSamples/s) and extended functionality (more modulation schemes, ComScope, etc).
