Chapter 8 The 9130 VSWR/DTF Reflection Measurement Option
Hardware requirements
140 9102 Handheld Spectrum Analyzer Software version 5.31
Hardware requirements
Following are the hardware requirements and recommendations for
performing measurements using the 9130 VSWR/DTF Reflection
Measurement Option:
–9160 VSWR/DTF Bridge
– 9150 Tracking Generator
– Calibration set for N or 7/16“
– Test port extension cable N or 7/16“.
For details on options and accessories for the 9102 please refer to
“Options and accessories” on page 5
Connecting the 9160 VSWR/DTF Bridge
For reflection measurements a measurement bridge is necessary. The
9160 VSWR/DTF Bridge is used to measure the load impedance of an
antenna or another device very precisely. It covers the full operational
frequency range of the 9102.
In order to set up the 9102 for VSWR/DTF reflection measurements
simply connect the 9160 VSWR/DTF Bridge to the RF in and RF out
connectors as well as to the Multi Port connector on the top of the
instrument.
NOTE
The test port extenstion cable is especially recommended for reflec-
tion measurements. A direct connection to antenna feeder cables is
in this case often not practicable as these cables are usually very
rigid. The test port extension cable can have a minimal influence on
measurement results. However, test results are not influenced in a
decisive way, so this effect can be disregarded.
