DESCRIPTIONThe tradition of delivering maximum value in microwave surveillance receivers continues with the introduction of the LITERAIL family of Miniature Digitizing Microwave Tuners.

SMR-7522
MiniatureMicrowaveDigitizingTuner
In addition to significant size and power reductions versus conventional set-on receivers, the SMR-7522 integrates signal digitization capability. Continuous Digital IF data is transmitted in VITA-49 format over 10 GbE via fiber optic cable for compatibility with the latest technology in digital demodulators, signal recorders and other off-board equip-ment. Unallocated FPGA resources can be used to imple-ment user-defined, pre-processing or specialized on-board demodulation of raw IF signal data. Despite its small size and low power, the SMR-7522 design achieves excellent phase noise performance, signal fidelity and out-of-band rejection.An integrated spectrum display generator provides continuous, FFT-based spectral data updates of the 100 MHz digital IF bandwidth. RF Sweep Mode provides a display of the RF spectrum as the tuner steps across the frequency range of interest, RF Scan provides a fine detail display of the RF spectrum. Spectral Data is made available on the 10/100 Ethernet.
Timing signal inputs provide the ability for the unit to accurately timestamp the digital IF data. IRIGB-123 analog timecode, 1 PPS signal, and 10 MHz reference signals from a precision timing source are used by the SMR-7522 to provide timestamping accuracy within 1nsec. In the absence of valid timecode and 1 PPS signals, the 10 MHz reference can still be used to phaselock multiple units to a common reference.
