Key Measurements
Reflection — Return loss
DTF — VSWR
1-Port cable loss
Reflection measures the impedance per-
formance of the cell-site transmission line
across the frequency range of interest in
VSWR or return loss.
•
More than 80 wireless frequency bands
are built into the instrument’s database
•
Capable of incorporating additional
frequency bands
•
User-definable limit line for automatic
Pass/Fail indication
•
Users can set up to 6 markers for trace
analysis
Distance to Fault (DTF) measures fault
locations in the cell site transmission
system to indicate signal discontinuities in
VSWR or return loss.
• Measurement distance: up to 1,500 m
(4,921 ft)
• High resolution mode with 2001 data
points
• More than 95 cable types are built into the
instrument’s database
• Capable of incorporating additional cable
types
• User-definable limit line for automatic
pass/fail indication
• Users can set up to 6 markers for trace
analysis.
1-Port cable loss measures signal loss
through a cable or other devices over a
defined frequency range.
•
User-definable limit line for automatic
pass/fail indication
• Users can set up to 6 markers for trace
analysis.
