VB1032 VSWR Bridge
Product Overview
VB1032 is used in combination with the R
IGOL 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
a
s 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.
