Ujjdwiurgh 1MHZ-1000MHz SWR Bridge Reflection Bridge For Antenna Network Measurement (A)

If combined with vector voltmeter or vector voltage measuring device can accurately measure the applied signal source vector impedance circuit, complete matching circuit testing and debugging. Widely used measure debugging, circuits and radio, television and communication equipment such as antenna measurements and debugging. is a sensor measuring the reflection coefficient for measurement, the output reflected signal has the amplitude and also the phase information, having a frequency width, high directivity characteristic. can be combined with the simple application of spectrum analyzer or scanner with the trace source, measure the return loss and reflection of the entire frequency band of the device; The following is an introduction to the general use of the reflection bridge: Reflective bridge directivity self-calibration: Connect the reflection electric bridge to the output of the tracking signal source of the spectrum analyzer, the frequency range of the spectrum analyzer is set to 1~1000MHz, the level is 100MHz per grid, and the output amplitude of the tracking signal source is 0dBm (others are also possible, the following are all measured by 0dBm output) The DUT end of the reflection bridge ( of the device under test) 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 Because there is a test end face (position reference), the capacitance of the outer conductor when the inner core is open, etc., can not be N Block is simply open circuit), the 1GHz signal is not high, simply open block Note down the spectrum analyzer amplitude.
