Introduction
Thank you for purchasing a RigExpert
AA-2000 ZOOM Antenna an d Ca bl e Analyz er ! We
did our best to make it powerful yet easy to use.
The analyzer is designed for measuring SWR
(standing wave ratio), return loss, cable loss,
as well as other parameters of cable and
antenna systems in the range of 100 kHz to
2000 MHz. A built-in ZOOM capability makes
graphical measurements especially effective.
An integrated Time Domain Reflectometer
mode can be used to locate a fault within the
feedline system. The analyzer is equipped
Bluetooth Low Energy
with a
wireless connection with your laptop, tablet or
smartphone.
The following tasks are easily accomplished by
using this analyzer:
• Rapid check-out of an antenna
• Tuning an antenna to resonance
• Comparing characteristics of an antenna
before and after specific event (rain, hurricane,
etc.)
• Making coaxial stubs or measuring their
parameters
• Cable testing and fault location, measuring
cable loss and characteristic impedance
• Measuring capacitance or inductance of
reactive loads

Checking the antenna
It is a good idea to check an antenna before connecting it to the receiving or transmitting
equipment. The SWR chart mode is good for this purpose. Also you can use Multé
tool located in Too ls . Multé will check your rig against all HAM bands defined in your
region and rate all bands where SWR lower than 3.0 in range of 1...5 stars. Select band
for detailed evaluation and press to run SWR char t for this band.
The picture on the lef t shows the result

Adjusting the antenna
When the measurement diagnoses that the antenna is off the desired frequency, the
analy zer can help in adjusting it. Physical dimensions of a simple antenna (such as a
dipole) can be adjusted knowing the actual resonant frequency and the desired one.
Other types of antennas may contain more than one element to adjust (including coils,
filters, etc.), so this method will not work. Instead, you may use the SWR mode, the
All parameters mode or the Smith chart mode to continuously see the results while
adjusting various parameters of the antenna.
For multi-band antennas, use the MultiSWR mode. You can easily see how changing
one of the adjustment elements (trimming capacitor, coil, or physical length of an
aerial) affects SWR at up to five dif ferent frequencies.

Cable fault location
To locate the position of a probable fault in a cable, just use the same method as when
measuring its length. Watch the behavior of the reactive component (X) near the zero
frequency:

• If the value of X is moving from 0 to +

Making 1/4-λ, 1/2-λ and other coaxial stubs
Pieces of cable of cer tain electrical
length are often used as components of
baluns (balancing units), transmission
line transformers or delay lines. To make
a stub of the predetermined electrical
length,
1. Calculate the physical length. Divide
the electromagnetic constant by the
required frequency (in Hz). Multiply the
result by the velocit y factor of the cable,
then multiply by the desired ratio (in
respect to λ).
2. Cut a piece of cable slightly longer than
this value. Connect it to the analyzer. The
cable must be open-circuited at the far
end for 1/4-λ, 3/4-λ, etc. stubs, and
short-circuited for 1/2-λ, λ, 3/2-λ, etc.
ones.
3. Switch the analyzer to the All
parameters measure ment mode . Set the
frequency the stub is designed for.
4. Cut little pieces (1/10 to 1/5 of the
margin) from the far end of the cable until
the X value falls to zero (or changes its
sign). Do not forget to restore the opencircuit, if needed.

Measuring the characteristic impedance
The
characteristic impedance
Usually, its value is printed on the cable by the manufacturer. However, in certain cases
the exact value of the characteristic impedance is unknown or is in question.
To measure the characteristic impedance of a cable,
is one of the main parameters of any coaxial cable.
1. Connect a non-inductive resistor
to the far end of the cable. The exact
value of this resistor is not impor tant.
However, it is recommended to use 50 to
100 Ohm resistors.
2. Enter the R,X chart mode and make
measurement in a reasonably large
frequency range (for instance, 0 to 200
MHz).
Example 1:
50-Ohm cable
RigExpert AA-2000 ZOOM
Example 1: 50-Ohm cable with 75
Ohm resistor at the far end.
Example 2: Unknown cable with 50
Ohm resistor at the far end.

3. Changing the display range and
performing additional scans, find a
frequency where R (resistance) reaches
its maximum, and another frequency
with minimum. At these points, X
(reactance) will cross the zero line.
Example 1:

Measurement of other elements
Although RigExpert A A-2000 ZOOM is designed for use with antennas and antennafeeder paths, it may be successfully used to measure parameters of other RF elements.
Capacitors and inductors
The analy zer can measure capacitance from a few pF to about 0.1 μF as well as
inductance from a few nH to about 100 μH. Since measuring of capacitance and
inductance is not a main purpose of RigExpert analyzers, the user will have to gain
some experience in such measurements.
Be sure to place the capacitor or the inductor as close as possible to the RF connector
of the analyzer.
1. Enter the R,X chart mode and select a reasonably large scanning range. Perform a
scan.
Example 1:
Unknown capacitor
RigExpert AA-2000 ZOOM
Example 2:
Unknown inductor
21
2. By using lef t and right arrow keys, scroll to the frequency where X is -25…-100 Ohm
for capacitors or 25…100 Ohm for inductors. Change the scanning range and perform
additional scans, if needed.
3. Switch to the Data at cursor screen by pressing the key and read the value of
capacitance or inductance.
Example 1:
Unknown capacitor
Example 2:
Unknown inductor
Transformers
RigExpert analyzers can also be used for checking RF transformers. Connect a 50 Ohm
resistor to the secondary coil (for 1:1 transformers) and use SWR chart, R,X chart or
Smith chart modes to check the frequency response of the transformer. Similarly, use
resistors with other values for non-1:1 transformers.

Traps
A
trap
is usually a resonant L-C network used in multi-band antennas. By using a
simple one-turn wire coil, a resonant frequency of a trap may be measured.
Example:
A coaxial trap constructed of 5 turns
of TV cable (coil diameter is 6 cm) was
measured.
A one-turn coil (about 10 cm in
diameter) connected to the analyzer
was placed, co-axially, a few
centimeters away from the measured
trap. The SWR chart shows a visible
dip near 10.3 MHz, which is a resonant
frequency of the trap.

Precautions
Never connect the analyzer to your antenna in thunderstorms.
Lightning strikes as well as static discharge may kill the operator.
Never leave the analyzer connected to your antenna after you finished operating it. Occasional lightning strikes or nearby transmitters may permanently damage it.
Never inject RF signal or DC voltage into the antenna connec tor of
the analyzer. Do not connect it to your antenna if you have active
transmitters nearby.
Avoid static discharge while connecting a cable to the analyzer. It
is recommended to ground the cable before connecting it.
Do not leave the analyzer in active measurement mode when you
are not actually using it. This may cause interference to nearby
receivers.
If using a personal computer, first connect the cabl e to the antenna
connector of the analyzer, then plug the analyzer to the computer
USB port. This will protect the analyzer from static discharges.
