Use in practice
- Rýchla kontrola antény – the display will immediately show you SWR, return loss and other parameters.
- Ladenie rezonancie – enables precise tuning of the antenna to the required frequency.
- Porovnanie pred a po udalosti – for example before rain/after a storm, to monitor changes.
- Výroba koaxiálnych pahýľov – the analyzer will help you determine the exact length of the stump.
- Testovanie káblov a lokalizácia porúch – analyzes losses, characteristic impedance and reveals hidden faults.
- Meranie L / C – can measure inductance up to ~100 µH and capacitance up to 0.1 µF.
How it works
Mozgom analyzátora je STM 32-bit RISC mikrokontrolér, ktorý riadi signál generovaný PLL čipom Si5351 (500 MHz). The latter creates two sine signals that are processed into CMOS square outputs. A resistance bridge with switching outputs is used for measurement, separately mixed to a 1.5 kHz signal and digitized with a 12-bit ADC. LCD aj klávesnica sú priamo pripojené k CPU, ktorý spracováva aj záznamy do flash pamäte.
Evaluation and conclusion
RigExpert AA-35 ZOOM it stands out thanks to its ease of use, robustness and a wealth of features at an entry-level price point. It stands out above all for its color display, self-calibration and practical graphic modes (SWR, R/X). The ability to measure reactive components, analyze cable faults and store results makes this device a versatile tool. Although it is not among the latest innovations, it still has a place in the market.
For radio amateurs who need a reliable analyzer for regular HF/VHF antenna tuning, cabling diagnostics or L/C component manufacturing, the AA-35 ZOOM is a great choice. More on https://rigexpert.com/antenna-analyzers/aa-35-zoom
