1. Based on SDR architecture, the msi001 RF front - end is used for 12 - bit quantitative sampling, using the stm32h743 processor, with a main frequency up to 480mhz. 2. It can receive frequencies from 50 kHz to 49.999 MHz, 50.001 MHz to 249.999 MHz, and 400 MHz to 2 GHz. 3. The sensitivity is 0.2 - 0.3V. 4. The anti - blocking performance is 85 dB. 5. The real - time sampling bandwidth is 160 kHz. 6. It has features such as variable filter, adaptive noise reduction, noise reduction, and noise suppressor. 7. The display is an IPS 3.5 - inch capacitive touch screen with backlight adjustment. 8. The working current should not exceed 300mA. 9. There is a dual - antenna input option version, with a front - end attenuation filter module that can attenuate up to 30dB, high - resistance input, short - wave sensitivity, and four additional front - end filters are added. 10. It can be connected to a computer via USB for IQ and audio communication. 11. Product Name: Radio Receiver 12. Display size: 3.5 inches 13. Interface: USB 14. Battery capacity: 3000mAh 15.
