Compact and slim space-saving design! π/4 Shift QPSK modem unit.
The "QM04A" is a four-wire full-duplex/two-wire half-duplex communication modem unit that complies with ITU-T Recommendation V.26 and uses π/4 shift QPSK (Quadrature Phase Shift Keying) method. The modulation and demodulation core is implemented using FPGA without dedicated LSI, reducing the risk of discontinuation. Additionally, it is a completely newly designed product manufactured domestically, and it is RoHS compliant. 【Features】 ■ Four-wire full-duplex/two-wire half-duplex communication, synchronous modem ■ Compact and slim space-saving design ■ Loopback diagnostics for both the local unit and the opposing device in opposing communication connections ■ Built-in self-test function that allows for error rate testing of the modem, including the line *For more details, please refer to the PDF document or feel free to contact us.
