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.
