Distance-To-Fault

The most common failure in a microwave
radio link is the transmission line, the waveguide
and/or coaxial cables which connect radio
equipment to the antennas. With the 54100A
Series optional Distance-To-Fault (DTF) Software
you can install and maintain tower equipment
with confidence.

Anritsu’s precision calibration components
and low source harmonics provide industry
leading return loss (or SWR) accuracy. With

0.1% distance accuracy, you’re sure to identify
degraded components or moisture quickly –
before the problem causes a failure. Automatic
anti-aliasing software and windowing filters
ensure the peaks on the DTF display are really
there, not erroneous fault indications caused by
re-reflections.

With most elliptical waveguide components
meeting 30 dB return loss performance, it’s
absolutely critical that the precision load used
for calibration is of the highest quality to achieve
repeatable, accurate measurements. Using
poor quality 50 W loads for DTF calibration will
cause abnormally high test data variations

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

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.

(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.

Distance-To-Fault Measurement
Accessories:

Anritsu Distance-To-Fault test systems utilize
standard diode detectors and measurement
accessories.

POWER DIVIDERS

These signal dividers are symmetrical, three­resistor tee designs that are used with the
Distance-To-Fault option and other applications

Distance-To-Fault mode

technicians easily locate
small problems before more
serious failures result.

The 56100A Scalar Network Analyzer operates with Anritsu’s
68C and 69B series synthesizers. The separate source
maximizes system performance and flexibility.

The 54100A Series Scalar Network Analyzers offer highly
integrated and economic network measurements

during maintenance test intervals. Instead of
saving time, technicians may find themselves
chasing non-existent problems.

Relative Group Delay

Optional relative group delay software identifies
signal distortion caused by bandpass devices
such as filters, receivers, power amplifiers, and
up/down converters. Group delay is a key
cause of high Bit Error Rate (BER). Group
delay is important for 1) CDMA and spread
spectrum communications 2) phase radars 3)
high capacity satellite and terrestrial microwave
links 4) PAL and HDTV television components
and other RF systems sensitive to phase
distortion.

Group Delay results from deviation in the
rate of change of phase response versus
change in frequency, df/dw. It indicates that
different frequencies travel at different speeds
through an RF device. RF systems which
depend upon phase coded information suffer
degradation when group delay is excessive.

The growth in wireless communications
places a heavy demand on available frequency
spectrum. More efficient communications
standards have digital phase modulation with

high bits-per-hertz specifications and high
bandpass filter rolloff rates. Each of these
conditions make the communications more
susceptible to group delay induced bit error
rate problems.

The 54100A saves time and expense by
measuring group delay with the same,
inexpensive network analyzer as is used for
other tests.

Calibration requires only an RF path
normalization with a standard RF detector.
Relative group delay specifications assume
measurement of bandpass devices. Frequency
sweep must include at minimum 20 dBr of
transmission rolloff from mid-band response.
For best results, set the frequency sweep to
cover more than 20 dBr rolloff is suggested.

Relative Group Delay Accuracy:

Typically < 1ns, < 5.0% of peak-to-valley range
with noise averaged. Assumes the band
limiting device within the DUT meets minimum
phase shift design. Devices such as SAW
filters, microwave phase equalizers, and branch

line couplers will have additional uncertainty.
Calibration: A transmission path
normalization is required.

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

Additionally, since adapters and attenuators
are not always labeled for frequency range, they
are occasionally used at frequency ranges
beyond their specification.

PRL finds these problems quickly. The
technique utilizes the same network analyzer
which is used for the production process: test
operators need only share an Airline and an
Offset SWR Autotester.

PRL Accuracy

When testing single port RF devices such as terminations, the principle uncertainty terms are
measurement directivity and channel accuracy. The directivity of a PRL measurement is limited by
the return loss of the precision airline. Channel accuracy includes noise effects, logarithmic
deviation, open/short cal uncertainty, linearity, and instrumentation stability. Additional second
order uncertainty terms such as test port match and source match are typically negligible.

Measurement Uncertainty (dB) = Channel Accuracy + Directivity Uncertainty
Measurement Uncertainty (dB) = - 0.5 - 20 log (1 + 10

- Ed/20

)

where, Ed = Airline Return Loss (dB) - Measured Return Loss (dB)

When measuring two port devices such as adapters and attenuators, an additional term (load
match) is required to account for the return loss of the precision termination which is attached to
port two of the device.

Measurement Uncertainty (dB) = - 0.5 - 20 log (1 + 10

- Ed/20

) -20 log (1 + 10

- Et/20

)

where, Et = Termination’s Return Loss (dB) - Measured Return Loss (dB)

With the implementation of ISO-9002, microwave test
specialists must perform verification of common test stand
components such as adapters and terminations on a daily or
weekly basis rather than at annual calibration cycles.

For ISO-9000 based manufacturing, the

The PRL measurement technique helps to
ensure test process compliance by verifying the

proper performance of test setup components.
The use of NIST traceable Precision Airlines
allow accurate calibration of those components.

Components For High Return Loss Device
Testing

Standard SWR autotesters are internally
terminated to a precision 50 ohm match. The
Offset SWR autotester replaces this 50 ohm
termination with a 15 dB or 20 dB offset
termination. This produces a readily measureable
reference vector.

During measurement, the S

reflection vector
of a high return loss will interfere with the
reference - creating a ripple pattern on the
display proportional to the DUT’s return loss.
The ripple pattern is automatically converted to
a return loss display trace by the precision
return loss mode’s software.

High Performance
Scalar Measurements

The Anritsu 56100A Scalar Network Analyzer
combined with a Anritsu 68C Series or 69B
Series Synthesizer, forms a powerful swept
frequency measurement system for both
production and design applications.

Measure insertion loss, insertion gain, or RF
power with 76 dB dynamic range over the 10
MHz to over 50 GHz frequency range—the
widest frequency range available in coax.
Measure device match as return loss in dB or as
SWR.

Separate detectors can be used on all four
inputs for multiple transmission measurements
on duplexers or matched amplifiers. Direct
detection allows simultaneous RF power
measurement at different frequencies for
example, at the RF, IF, and LO frequencies of
mixers and converters.

Versatile

Transmission and reflection measurements can
be viewed simultaneously. Both traces can be
scaled independently in dB, dBm or SWR.

Measurement of the ratio of two detector inputs
may be applied to either channel for enhancing
accuracy or for viewing differences. Built-in
calibration allows subtraction of the unwanted
transmission frequency response and the
average of open/short reflections.

A Volt Mode is available for displaying voltage
(with Volt Mode Adapter Cable). A 0 to 10 Volt
Sweep Ramp Output Mode is also available.
These modes, combined with a versatile Trace
Memory Mode, allow easy testing of VCOs, PIN
diodes, and detectors.

Measurements

Measurement systems using the 56100A Scalar
Network Analyzer include components from 1
MHz to 110 GHz.

Function: The 56100A has four detector inputs
and two independent channels for measurement
and display of detected RF power from Anritsu
560 Series Detectors and SWR Autotesters.
Two independent channels display RF power
(dBm), Transmission Gain or Loss in (dB), or
reflected power. Voltage may be displayed with
optional Volt Mode Adapter Cable.

Measurement Modes: Measures and displays
in dB swept transmission and return loss
characteristics. Power is displayed in dBm.
Complete measurement parameters for all
modes are displayed.

Frequency Range: 10 MHz to over 50 GHz in
coax using Anritsu 560 Series Detectors and
SWR Autotesters. Waveguide measurement
components to 110 GHz support transmission,
reflection, and power measurements.

Detectors

SWR Autotesters

Autotesters are bridges with integrated
detectors to simplify return loss measurements
in coaxial systems. 5400 series RF autotesters
and 560 series microwave autotesters have
fixed test port connections. They offer the best
possible directivity for accurate measurement of
return loss.

When a variety of DUT’s with differing test
port connectors need to be measured, the
560-98C50 convertible SWR autotesters reduce
capital equipment and maintenance costs.
These autotesters accurately measure the return
loss or SWR of devices with SMA, 3.5mm or K
connectors. Six interchangeable test port heads
(male and female for each connector standard)
are precision tuned to the convertible autotesters
internal bridge circuit.

Detectors

The 5400 and 560 Series Detectors use zero­biased Schottky diodes. Measurement range is

-55 dBm to +16 dBm using single cycle per
sweep AC detection, Auto-zeroing with DC
detection during the frequency sweep. Optional
extender cables of over 3000 feet can be used
with the 54100A Series. Contact local sales
representative for special cables.

The inexpensive test port heads save repair
and calibration costs because they are
interchangeable. Repetitive connect/
disconnection cycles will eventually wear out
test port connectors – especially when excess
torque is applied and the connector’s mating
surfaces are rotated against each other.

It is common practice to reduce maintenance
costs by using adopters or connector savers on
the test port of the directional device.
These adopters attached to the test port reduce
measurement accuracy. Directional devices are
tuned for optimum directivity at a specific phase
reference point, known as the test port. Any test
port adapter will degrade the effective directivity.
Convertible autotesters from Anritsu with
interchangeable test port heads eliminate this
measurement degradation.

Autotester accuracy is composed of error due
to directivity and error due to test port match.
Unless the DUT has very poor return loss (high
SWR), directivity will be largest source of error.
When an adapter is used at the test port, use
Effective Directivity to determine possible errors.
Note: Return loss errors due to source
harmonics will be significant when the harmonic
level is within 10 dB of the DUT’s measured
return loss.

Millimeter Wave
Measurement Systems

The Anritsu Millimeter Wave Reflectometers are
designed to operate with the 54100A and
56100A Scalar Measurement Systems. The
system source must cover at least to 20 GHz to
operate the millimeter wave
reflectometers. The millimeter
wave multiplier includes
subharmonic filters and an
isolator, to dramatically improve
reflection accuracy.

Excellent multiplier source
match provided by the internal
isolators and the improved
detector return loss allow
accurate, simultaneous return loss
and transmission measurements.

110 GHz Reflectometers

54000 Series Millimeter extensions with ultra­low -55 dBc harmonics and > 40 dB typical
directivity provide precision measurements in
waveguide to > 110 GHz. The multiplier based
reflectometers compact a bench full of waveguide
test components into a single, rugged package.

Manufacturing and engineering benefit from
the high accuracy and low cost of Anritsu’s
millimeter wave measurement systems. The
multiplier based design offers low source
harmonics, high reliability, rugged construction,
small size, and fast setup.

The Reflectometers integrate amplifiers,
multipliers, isolation, filters, couplers, detector,
and detector matching circuits in one small
package. High quality detectors maximize two
port transmission measurement accuracy.

High Performance, Low Pricing – Anritsu’s V-band and W-band Reflectometers are designed to operate with the 54147A Scalar
Measurement System. Test port match is excellent and source harmonics are better than -55dBc.

For a typical test system the most common
causes of measurement uncertainly are:

• Excessive source harmonics

• Poor effective directivity due to test port

adapters

• Poor quality test components

Transmission Loss or Gain Measurement

Uncertainties from the frequency response of
components are automatically subtracted from
test data during the path calibration procedure.
Overall accuracy is then:

Channel Accuracy
+ Mismatch Uncertainty
+ Distortion From Source Harmonics
Transmission Measurement Accuracy

Effects of source, test device, SWR Autotester,
and detector mismatch can be significant. This
mismatch uncertainty is minimized by the
exceptionally low reflection characteristics of
Anritsu’s detectors, sources, and SWR
Autotesters. Anritsu’s ultra low source
harmonics maximize the accuracy of
measurements on filters, receivers, mixers, and
amplifiers.

Channel Accuracy (25°C):

Return Loss Measurement Accuracy

Uncertainties resulting from SWR Autotester and
source frequency response and from system
open and short characteristics are subtracted
automatically from test data.
Overall accuracy is then:

Channel Accuracy
+ Autotester Accuracy
+ Distortion From Source Harmonics
Return Loss Measurement Accuracy

The Return Loss measurement of a low pass filter is grossly
distorted when high harmonics are present. When the
source’s fundamental frequency passes 2 GHz, the second
harmonic (at 4 GHz) enters the lowpass filter’s reject band;
thus, 100% of the second harmonic power is reflected back
toward the source. Thus, the reflected harmonic power is
measured and then erroneously displayed as the return loss
characteristic between 2 and 4 GHz.

The Return Loss measurements (above) were created by the
same bandpass filter. Measurement was performed with and
without a test port adapter. Differences in the ripple display
are caused by the vector error signal of the adapter’s SWR
reflection, which alternately adds and subtracts from the
true return loss magnitude.

Millimeter Wave Detectors

Errors due to source harmonics are most evident when
testing wide band filters. As the source’s fundamental
frequency passes 2 GHz, the -33 dBc second harmonic is at
4 GHz – within the pass band of the wideband filter.
