VB1032 VSWR Bridge
Product Overview
VB1032 is used in combination with the RIGOL DSA series spectrum analyzer to measure
S11-related parameters (such as return loss, reflection coefficient and VSWR). VB1032 provides three N (Female) connectors as shown in the figure below. ü IN: Signal input terminal. Here the signal generator or the output terminal of the
tracking generator of the spectrum analyzer is connected.
ü OUT: Signal output terminal. Here the
power meter or the RF input terminal of the spectrum analyzer is connected.
ü DUT: Here the device under test is
connected.
Measurement Connection Connect VB1032 to the spectrum analyzer as shown in the figure on the right. ü Connect the spectrum analyzer
Use 2 Dual N (Male) adaptors to connect the output terminal of the tracking generator and the RF input terminal of the spectrum analyzer to the IN terminal and OUT terminal of
the VSWR bridge respectively.
ü Connect the device under test
Do not use cables or adaptors as far as possible to avoid additional reflection.
Typical Applications ü Measurement of the S11-related parameters of the filter, amplifier, mixer, etc.
ü Resonant frequency and VSWR tests of the antenna.
