Feature:1. The large heat dissipation area of the receiver can better maintain long-term operation.2. The alloy material is coated with anticorrosion paint, the surface is smoothly and the service life is greatly improved.3. The product is light in weight and can be operated with one hand, reducing operator fatigue.4. With 1kHz-2000 MHz continuous coverage, uses 14-bit ADC silicon technology, and has a visible bandwidth of up to 10MhZ.5. Support for Windows/Linux/Android/OS X/Raspberry Pi 3, small size and good performance.Specification:Item Type: SDR ReceiverMaterial: Aluminum alloyFeatures: 1.1kHz-2000 MHz continuous coverage;2.14-bit ADC silicon technology;3. Up to 10MhZ visible bandwidth;4.11 Highly selective built-in front-end preselection filter;5.For Windows/Linux/Android/OS X/Raspberry Pi 3;6. Free world-class software;Compared with the original RSP1, the main additional features of RSP1A:1. When the sampling rate is lower than 6mhz, the ADC resolution is increased to 14-bit native resolution, and it is increased to 16-bit when decimating;2. Enhanced RF preselection (compared with the original RSP1, higher filter selectivity plus 4 additional subbands) to reduce the spurious response level;3. Improved LNA structure with variable gain-RSP1 has only one gain step;4. Improved intermodulation performance;5. The performance is extended to 1kHz to 2GHz, single antenna port;6. Use 0.5ppm TCXO (software can be fine-tuned to 0.01ppm) to improve frequency stability;7. Optional broadcast AM/FM/DAB notch filter;8.Radio frequency shielding in a sturdy plastic housing.Note: 1 An open API allows developers to create new demodulators or applications around the platform.2RSP1A is also compatible with HDSDR, SDR console and software packages3. Using the free professional SDRUno software, you can enjoy all operating modes while monitoring the spectrum up to 10 MHz in real time. SDRUno software allows you to operate 1 to 4 independent virtual SDR receivers within the 10MHz bandwidth selected by the hardware. The actual number of virtual SDR receivers is limited by the processing power of the PC used.RSP1A Specifications: Low Current: 185mA (not including bias current)ConnectivitySingle 50 RF connector (SMA)USB 2.0 (High Speed) Type B SocketFrequency Range: Continuous coverage 1kHz-2GHzFrequency Tolerance: 0.5ppm (maximum)ADC Features: Sampling Frequency: 2-10.66MSPS14-bit native ADC (2-6..48MSPS)12 bits (6.048-8.064MSPS)10 bits (8.064-9.216MSPS)8 bits (>9.216MSPS)Bias voltage TSoftware optional 4.7V at 100mAReferences: High stability 0.5PPM TCXOCan be fine-tuned to 0.01PPM on siteMaximum recommended input powerContinuous 0dBm, short-term 10dBmTypical Noise Figure: 18dB at 2MHz15dB at 12MHz15dB at 25MHz15dB at 40MHz3.3dB at 100MHz3.3dB at 200MHz7.7dB at 386MHz3.6dB at 660MHz5.0dB at 1500MHz6.3dB at 1800MHzIf The Pattern: Zero IF, full IF bandwidthLow intermediate frequency, intermediate frequency bandwidth1.536MHzIf The Bandwidth: 200 kHz300 kHz600 kHz1.536 MHz5.0 MHz6.0 MHz7.0 MHz8.0 MHzFront-end Filtering: Automatic configurationLowpass: 2 MHzBandpass: 2-12 MHz12-30 MHz30-60 MHz60-120 MHz120-150 MHz250-300 MHz300-380MHz380-420MHz420-1000MHzHighpass: 1000 MHzNotch Filter: FM filter>50dB 85-100MHzMW filter>30dB 660-1550kHzDAB filter>30dB 165-230MHz>3>30dB 660-1550kHz>30dB 660-1550kHz.Package List:1 x Connection Line1 x Antenna1 x Receiver1 x User Manual
