Reflection RF Bridge, Standing Wave Direction Bridge for Antenna Network Measurements (A)

The following is an introduction to the general use of the reflection bridge: self-calibration of the directivity of the reflective bridge: connect the electrical reflection bridge to the output of the tracking signal source of the spectrum analyzer, the frequency range of the spectrum analyzer is set to 1~1000 MHz, the level is 100 MHz per grid and the output amplitude of the tracking. Signalsignal source is 00dBm (others are also possible, is a sensor that measures the reflection coefficient for network measurement. The output reflected signal has the amplitude and also the phase information, a frequency width and a high pattern. can be combined with the simple application of an spectrum analyzer or scanner with the trace source. measure the return loss and reflection of the entire frequency band of the device. In combination with a vector voltmeter or vector voltage meter, you can accurately measure the vector impedance circuit of the applied signal source and complete testing and debugging of the matching circuit. Widely used measurement of debugging, circuit and radio, television and communication equipment such as antenna measurements and debugging. The following are all measured using the 0 dBm output). The DUT end of the reflection bridge ( of the device to be tested) is open. ( is connected, the frequency is low and the requirements are not high; the frequency is high, the requirements are high, the opener must be connected Since there is a test end (position reference), the capacity of the outer conductor may not be when the inner core is open, etc. N-block is simply open circuit), the 1GHz signal is not high, simply open block N. Write down the amplitude of the spectrum analyzer.
