Rigol VB1020 VSWR Bridge

VSWR Bridge VB1020 with 1 MHz to 2 GHz measuring range, is used in combination with the RIGOL DSA series spectrum analyzer to measure S11-related parameters (such as return loss, reflection coefficient and VSWR). VB1020 provides three N female connectors as shown in the figure below. IN: Signal input terminal. Here the signal generator or the output terminal of the tracking generator of the spectrum analyzer is connected. OUT: Signal output terminal. Here the wattmeter or the RF input terminal of the spectrum analyzer is connected. DUT: Here the device under test is connected. Measurement Connection Connect VB1020 to the spectrum analyzer as shown in the figure   Connect the spectrum analyzer Use 2 adaptors (n male-N male) to connect the output terminal of the tracking generator and the RF input terminal of the spectrum analyzer to the IN and OUT terminal of the VSWR bridge respectively Connect the device under test Do not use cables or adaptors as far as possible to avoid additional reflection.   Typical Applications Measurement of the S11-related parameters of the filter, amplifier, mixer, etc. Resonant frequency and VSWR tests of the antenna.
