HIGH-PRECISION CLOCK: Software-defined radio uses a high-precision clock with a resolution of 0.1-0.5 PPM. The 1 MHz to 6 GHz operating band, 20 MHz RF bandwidth, and 2 to 20 Msps sampling rate provide excellent performance.WIDE APPLICATION: Software-defined radio is used in the sense of monitoring of ships (AIS), automobiles (TPMS), E utility meter transponder (ITRON ERT), etc.APPLICABLE: Software-defined radio is applicable to research wireless communication technologies for wireless applications such as WiFi, LTE, and other wireless application systems. Sampling, filtering, synchronization, multiplexing.SOUND INPUT AND OUTPUT FUNCTIONS: The built-in microphone, built-in speaker, and external speaker are designed to enable sound input and output functions, with the built-in speaker and external speaker switching automatically.3.2-INCH LCD DISPLAY: Large 3.2-inch LCD display with 240 x 320 RGB resolution with resistive touchscreen. Wear-resistant function knobs with four-way arrow knobs, 360-degree rotary knobs, and selection knobs.Specifications :Item Type: Software DefinedRadio Kit Material: Acrylic, PCB, LCDScreen Size: 3.2 inch TFT 240 x 320 DuplexMode: Half-duplexTransceiver Operating Frequency Band: 1 MHz to 6 GHzTransmit Power:5 to 15 DBm (10 to 2,150 MHz)13 to 15 DBm (2,150 to 2,750 MHz)0 to 5 DBm (2,750 to 4,000 MHz)10 to 0 DBm (4,000 to 6 000 MHz)Received Power: -5 DBm Clock Accuracy: 0.1 to 0.5 ppmSpeaker: Built-in Sound Input: 3.5mmPower Connector: Micro USBAntenna Socket: SMAOther Interfaces: Memory Card Slot (Supports up to 128GB, Comes without)Battery Type: 2,000mAh Lithium-ion Battery (Built-in)Applicable Platforms: WiFi, LTE, etc.How to Use :DirectUse Packing List:1 x Receiver 1 x USB Cable 1 x 40MH to 6GHz Telescopic Antenna 1 x Storage Bagor1 x Receiver 1 x USBCable 1 x 40MH to 6GHz Telescopic Antenna 1 x 8 dBi 2.4/5/5.8 GHz Antenna1 x Set x 12 dBi 700-2700 MHz Antenna (2 pcs)1 x Storage Bagor1 x Receiver 1 x USBCable 1 x Telescopic Antenna 40MH to 6GHz 1 x 8dBi 2.4/5/5.8GHz Antenna1 set x GSM/3G/4G antenna 35 dBi (2 pcs)1 set x antenna 5 dBi 40 MHz to 860 GHz (2 pcs)1 set x antenna 12 dBi 700-2 700 MHz (2 pcs) )1 x Amplifier1 x Connection Cable1 x StorageBag
