Page 5: Introduction
Introduction Thank you for purchasing a RigExpert AA-3000 ZOOM Antenna and Cable Analyzer! 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 3000 MHz. -
Page 6: Operating The Aa-3000 Zoom
Operating the First time use AA-3000 ZOOM Please insert three AA sized batteries (alkaline, Ni-MH or LiPO accumulators) into the battery compartment of the analyzer, watching the polarity. Press the (Power) key located at the bottom-right corner of the keypad to turn on the analyzer. -

The rest of the connector, as well as the cable, should remain stationary. If you twist other parts of the connector when tightening or loosening, damage may easily occur. Twisting is not allowed by design of the N-connector. RigExpert AA-3000 ZOOM... -
Page 8: Swr Chart
SWR chart Once your antenna is connected to the analyzer, it is time to measure its charac- teristics. Press the (SWR chart) key to open the SWR chart screen, then press (OK) to start a new measurement. A few moments later, the result will be displayed on the analyzer’s screen. -

Page 16: Applications
Applications Antennas Checking the antenna It is a good idea to check an antenna before connecting it to the receiving or transmit- ting equipment. The SWR chart mode is good for this purpose. Also you can use Multé tool located in Tools. 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. -
Page 17: Coaxial Lines
• In the open-circuited case, resonant frequencies correspond to (left to right) 1/4, 3/4, 5/4, etc. of the wavelength in this cable; • For the short-circuited cable, these points are located at 1/2, 1, 3/2, etc. of the wavelength. RigExpert AA-3000 ZOOM... - Page 18 Cable length measurement Resonant frequencies of a cable depend on its length as well as on the velocity factor. A velocity factor is a parameter which characterizes the slowdown of the speed of the wave in the cable compared to vacuum. The speed of wave (or light) in vacuum is known as the electromagnetic constant: c=299,792,458 meters (or 983,571,056 feet) per second.
- Page 19 16.4 / (1/4) x 9,400,000 = frequency (in Hz). 616,640,000 feet per second 3. Finally, find the velocity factor. Just 188,000,000 /299,792,458 = 0.63 divide the above speed by the electro- - or - magnetic constant. 616,640,000 /983,571,056 = 0.63 RigExpert AA-3000 ZOOM...
- Page 20 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 –∞ to 0, the cable is open-circuited: •...

- Page 22 Measuring the characteristic impedance The characteristic impedance is one of the main parameters of any coaxial cable. 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, 1.

Page 24: Measurement Of Other Elements
The analyzer can measure capacitance from a few pF to about 0.1 µF as well as induct- ance 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 experi- ence in such measurements. - Page 25 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.
- Page 26 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.

Page 28: Annex 2 Precautions
Annex 2 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 fin- ished operating it. Occasional lightning strikes or nearby trans- mitters may permanently damage it. -

Connect either open or short circuited cable to the analyzer and press (OK) to start. The analyzer will immediately show resonant frequencies for both quarter- wave and halfwave stubs. Longer cables have lower resonant frequency. RigExpert AA-3000 ZOOM... - Page 30 Length & VF Knowing the velocity factor, a physical length of a cable can be easily calculated. Press the (Up) button and edit the value of the velocity factor, then press (OK) to start measurement. To find the velocity factor of an unknown cable, press the (Down) key and enter the physical length, then press...

- Page 32 Cable impedance To measure the characteristic imped- ance, use a piece of an open circuited cable: a half of a meter (or a foot) or longer should be fine. Press (OK) to start. Next, the far end of the cable should be short circuited.

- Page 36 Unlike many other commercially-available reflectometers, RigExpert AA-3000 ZOOM does not send pulses into the cable. Instead, another technique is used. First, R and X (the real and the imaginary part of the impedance) are measured over the whole frequency range (up to 3000 MHz). Then, the IFFT (Inverse Fast Fourier Transform) is applied to the data.

Change of velocity factor corrects range distances. The result of measure can be viewed in three modes: impulse response, step response, impedance response.
