RSPduo Dual Tuner 14-bit SDR

KEY BENEFITS

• Simultaneously receive on two totally independent 2MHz spectrum windows anywhere between 1 kHz and 2 GHz
• Simultaneous processing from 2 antennas enables direction-finding, diversity and noise reduction applications
• Ideal for cross band full-duplex reception, e.g. HF + VHF or VHF + UHF
• Simultaneous Dump1090 and VHF ATC reception
• Simultaneous monitoring and recording of 2 ISM bands
• Covers all frequencies from 1 kHz through VLF, LF, MW, HF, VHF, UHF and L-band to 2 GHz, with no gaps
• Receive, monitor and record up to 10MHz of spectrum at a time (single tuner mode)
• External clock input and output for synchronisation purposes, or connection to GPS reference clock
• Excellent dynamic range for challenging reception conditions
• Works with popular EXTIO-based SDR software (available mid 2018)
• Software upgradeable for future standards
• Strong and growing software support network
• API provided to allow demodulator or application development
• Calibrated S meter/ RF power and SNR measurement with SDRuno (including datalogging to .CSV file capability)
• Ideal for portable monitoring of ISM/ IoT/ Telemetry bands <2GHz
• World-class technical support via www.sdrplay.com

KEY FEATURES

• Dual tuner provides independent coverage from 1 kHz to 2 GHz using 2 antenna ports simultaneously
• 14-bit ADC silicon technology (not another 8 bit dongle!)
• Up to 10 MHz visible bandwidth (single tuner mode) or 2 slices of 2 MHz spectrum (dual tuner mode)
• 3 software-selectable antenna ports ( 2 x 50 Ohms and 1 x 1k Ohms high impedance balanced/unbalanced input)
• High impedance antenna port (1 kHz to 30 MHz) with selectable MW notch filter and choice of 2 pre-selection filters
• Software selectable AM/FM and DAB broadcast band notch filters for the 2 SMA antenna (1 kHz to 2 GHz) antenna ports
• External clock input and output enables easy synchronisation to multiple RSPs or external reference clock
• Powers over the USB cable with a simple type B socket
• 11 high-selectivity, built in front-end preselection filters on both the 2 SMA antenna ports
• Software selectable multi-level Low Noise Preamplifier
• Bias -T power supply for powering antenna-mounted LNA
• Enclosed in a rugged black painted steel case.
• SDRuno—World Class SDR software for Windows
• Documented API for new apps development
