The Best Anritsu 54107A

Anritsu 54107A

Specifications
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: < 0.1% 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
Introduction to Anritsu Scalar Analyzers 54100A Series optional software
2
Anritsu offer a comprehensive range of scalar analyzers for economic network measurements to 110GHz.
The 56100A scalar analyzer used in conjunction with a 68C series synthesizer offers the very best RF performance in a scalar measurement system. The 68C series synthesizer and 56100A analyzer communicate over a private GPIB link to form an integrated scalar measurement system.
The 56100A/68C scalar measurement
systems offers 10MHz to 50GHz frequency
coverage with –40dBc harmonics, up to
+17dBm levelled power and fully synthesized
sweeps. This combination is ideal where the
best possible frequency accuracy and dynamic
range are required.
Mixers and other frequency conversion
devices can also be characterised by using two
synthesizers in the system to generate
frequency sweeps with a fixed offset.
The 54100A series integrated scalar network
analyzers have built in crystal referenced
sources to provide an economical and compact
solution. They are ideal for production of devices
such as filters and amplifiers from 1MHz to
50GHz. Optional software adds; distance to
fault measurements for field testing of
waveguides, cables and antennas, relative
group delay software for economic filter
characterisation and precision return loss that
adds up to 20dB directivity improvement to

SWR measurements.
For scalar network measurements to 110GHz
both 54100A and 56100A are complemented
by the millimeter wave reflectometers.
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 nondispersive coaxial cable in front of the waveguide transmission line.

Precision Return Loss
Precision Return Loss (PRL) is a technique
which uses vector signal addition principles to
extend the directivity of scalar network analyzer
(SNA) measurements. The 15 to 20 dB
directivity improvement allows accurate
verification and calibration of very high return loss devices such as terminations, attenuators,
and adapters – components which are common
to almost every RF test bench.

Test bench components are susceptible to a
variety of problems including:
1) Repeated excess torque
2) Drops to the floor
3) Accumulation of dirt
