The handheld monitoring receiver 3943B is easy to operate.
The overall size of the handheld monitoring receiver is 182.5mm × 289mm × 69mm, and the total weight of the machine is less than 3.5kg. The operating time on battery is 3 to 4 hours, and the display is a 10.1-inch TFT with an integrated touch screen. It is equipped with multiple functions such as searching, intercepting, measuring, analyzing, demodulating, direction finding, and positioning of radio signals, and can be used for key activities such as radiation monitoring, coverage measurement, rapid detection and positioning of illegal radiation/interference sources, and compliance with ITU specifications for radio security and other tasks. The entire machine adopts a full touch screen design, and the software supports multi-touch interactive mode. The touch operation experience of a smartphone has been fully transplanted to the monitoring receiver. Users can easily complete operations such as zooming in and out on the display track, moving windows, and setting parameters using touch gestures. It provides a user-friendly UI interface to ensure that users can operate the monitoring receiver just like using a mobile phone or tablet computer.
