AA-2000 ZOOM: the high-end class analyzer
For some, it will be time for active contests.
A curious mind requires more experiments with frequencies, bands, and types of radio communication with the environment.
You want to get the most out of your equipment. And also protect from the effects of experiments with radio communications.
What can the AA-2000 ZOOM do?
The main parameter of the antenna is the standing wave ratio. Even more revealing is its frequency dependence. SWR characterizes the degree of matching of the antenna with the output or input of the transmitter and receiver. If the SWR is equal to one, this means perfect matching. There are no energy reflections and no standing waves in the feeder. The opposite result is infinity. By the way, energy is reflected and returned. In this case, the output stage of the transmitter can be damaged. Although in most industrial transceivers with high power, protection against increased SWR is installed. The results of the measuring are displayed on the chart. The small triangle at the bottom is where the SWR reaches its minimum.
The transmission speed varies widely.
This way, you measure the SWR at five specified frequencies at once.
There is no need to do it separately, even again, due to a failure in the settings after each measurement loop.
Owners of multi-band antennas highly appreciate them.
The mode allows quick identification of whether the antenna can operate in any radio amateur band.
You will see a list with preliminary frequency and SWR data if yes. Choose the desired position and immediately go to this range on the chart.
The measurements are carried out continuously. Сan explore three bands at the same time.
It is sometimes beneficial to have custom, more flexible bands for advanced analyzer usage instead of rigid amateur regional bands.
In My Bands mode, you manage ten band plans, each containing up to 100 defined bands.
Calibration data sets
When you use Fixture for measurements in the system, you must repeat its calibration every time. This data is needed to exclude the influence of the cable on the measurement results.
There are various auxiliary Fixtures. Their choice depends on the measured system. If you often use them, you will repeat many routine calibrations.
Now imagine that this is no longer necessary. You just connect Measurement Fixtures and load the calibration OSL file. AA-2000 ZOOM will do the rest.
If you want to save time and nerves with this helper, load data from previous calibrations you need. The analyzer saves 10 of these files.
Cable length measurements
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 some instances, the exact value of the characteristic impedance is unknown or in question.
To find the characteristic impedance of a cable, connect a non-inductive resistor to its far end. Use the R, X chart modes to get the resistance and reactance data. To determine the impedance characteristics, use the automated coax calculation tools from the Tools Menu.
Cable Length and VF
The resonant frequencies of a cable depends on its length and the velocity factor.
A velocity factor is a parameter that characterizes the slowdown of the wave speed in the cable compared to a vacuum.
You need to know the velocity factor when building devices on feeder lines, such as quarter-wave transformers. The Cable Length and VF tool will help do it. As the name implies, it also measures cable length.
Looks for inhomogeneities in the feeder line. It allows you to find faults also in power lines and wiring.
The instrument measures the frequency response and performs a fast inverse Fourier transform. The result is an impulse response.
The reflectometer can also find the cable length. It ranges from 14 m to 404 m. You can see the resistance module (ІZІ) and Impulse Response (IR).
Helps set up 1/4-λ, 1/2-λ, and other coaxial stubs. Measure with an open end. AA-2000 ZOOM communicationsRigExpert VNA can work remotely via Bluetooth with mobile devices. You need the Antscope app to achieve this. Communicates with the computer via USB.
The device is so functional and MNo that it can easily be used in a professional environment, for example, for laboratory testing. Moreover, beginner HAM radio operators can work it without reading the… If only to find out all the powerful potential hidden in it.
After all, we have yet to say everything…
