Measurement set-up
The VSWR bridge HZ 5 7 has  N female
N-connectors.
IN = input to the bridge
Here the signal source is to be connected. This
may be a HF-generator, the tracking generator of
a spectrum analyzer or network analyzer.
OUT = Output of the bridge
At this output a voltage is available the amplitude
and phase of which are proportional to the re-
ection coefcient of the DUT and which may be
measured using a suitable detector. A suitable
detector may be a HF-wattmeter, the input of a
spectrum analyzer or network analyzer.
DUT = Device under test – connection
The DUT should be connected as closely as
possible, any cable or adapter inbetween will
affect the measurement as they cause additional
reections.
In order to keep the connections short between
the VSWR bridge HZ57 and the Hameg Spectrum
Analyzer (HMS1010 or HMS010) the bridge has
been designed so that it can be connected directly
via N to N adapters. Two adapters are enclosed
with the instrument.
