DISTANCE-TO-FAULT
The optional Distance-To-Fault software displays impedance
discontinuities versus distance based on a swept frequency
measurement of transmission line mismatch. The software
is available by ordering Option 7 with 54100A Series
Network Analyzers.
Measurements: Distance-To-Fault (meters or feet), Return loss or
SWR of fault.
Frequency Sampling: 256, 512, or 1024 frequency points.
Window Functions: Hamming, 2-term, – 42 dB sidelobes;
Blackman-Harris, 3-term, – 67 dB sidelobes.
Anti-aliasing: Filtering of post detected data rejects indications of
false faults caused by signal re-reflections during high reflection
fault conditions or out of band sweep on antenna systems.
Distance Accuracy:
<
0.01% of range or 2 mm dependent upon
knowledge of the propagation velocity for the device under test and
the frequency sweep range.
Dynamic Range:
>
80 dB, depending upon calibration component
return loss and operating frequency range.
Return Loss Amplitude Accuracy: Effective Directivity is
dependent upon the return loss of the precision termination used
during calibration.
Distance Range: 1 to 5000 meters depending on measurement
frequency range and hardware configuration.
Distance Resolution (of one fault):
0.4% of total distance (256 frequency measurement points),
0.2% of total distance (512 frequency measurement points),
0.1% of total distance (1024 frequency measurement points).
Transmission Lines Supported:
• Coaxial Cable
• Waveguide
• Waveguide with Coaxial Cable Input
Transmission line loss and velocity factor are corrected by the
software. Waveguide dispersion is corrected based on the cutoff
frequency, fc. For waveguide with coaxial cable input, a special
operating mode is utilized to automatically compensate for the
length of non-dispersive coaxial cable in front of the waveguide
transmission line.
Distance-To-Fault Measurement Accessories:
Wiltron Distance-To-Fault test systems utilize standard diode
detectors and measurement accessories.
POWER DIVIDERS
These signal dividers are symmetrical, three-resistor tee designs
that are used with the Distance-To-Fault option and other applica-
tions requiring two inputs to be combined into a single output.
Maximum Input Power: +30 dBm
3 dB ATTENUATORS
RECOMMENDED TERMINATIONS
Terminations are required for calibration and are occasionally
used for terminating the output of the coaxial cable under test.
Contact your local sales representative for additional precision
termination models.
