Multi-channel Wide Band Level Detector


    

500MHz to 43.5 GHz band level detector(FPC-3000)

This RF detection unit detects 500MHz to 43.5GHz radio waves and converts them to DC voltage for simple inspection of 5G equipment development and manufacturing (mass production) lines. Up to 9 power detection units can be installed (expanded) and configured with the required number of units.
In the 5G equipment development and manufacturing stage, it is only necessary to measure that “radio waves are emitted” or “radio wave beams are being directed” from the equipment, and pass / fail without the need for expensive measuring instruments such as a spectrum analyzer or tester. Judgment (see next section) is possible. The converted voltage can be output simultaneously with a linearly changing analog output and a digital output that can be imported to a personal computer via USB.

FPC-3000 utilization flow

Reference examples of how to use FPC-3000 are shown in the power test and beam forming test.

Relative value evaluation method using FPC-3000 is dedicated to prototype model and mass production sample Dell. Use the terminal measured strictly by the measuring instrument as the reference terminal. Mass production started Before starting, each antenna coupler receives the radio waves transmitted from this reference terminal. The FPC-3000 controller uses software to convert the received power into voltage. Stored in master software and saved as master data to complete production preparations and mass production start.

Place the manufactured terminal in the measurement shield box (our FS-1905).

In power tests, radio waves are emitted from manufactured terminals and received by antenna couplers. The radio wave is converted to voltage by FPC-3000. FPC-3000 control during production preparation Compared with the master data voltage stored in the software, the preset voltage If it is within the range, it will be judged as “pass”, and if it is outside the range, it will be judged as “fail”. Simple measurement flow suitable for mass production.

In the beamforming test, the beam is controlled from a manufactured terminal in a specific direction. It emits radio waves. Received by all 9 antenna couplers of FPC-3000 Convert radio waves to voltage, and then come out of the antenna coupler in the intended direction If the received voltage is higher than the voltage from other antenna couplers, it is judged as “Pass” To do. FPC-3000 can realize a simple measurement flow suitable for mass production.
