UTS1000-AMA

Why Enable the Analog Demodulation Analysis Option?

The UNI-T UTS1000-AMA Analog Demodulation Analysis option is an invaluable tool for engineers working with analog-modulated signals in fields like broadcasting, telecommunications, and RF circuit development. With the ability to analyze both AM and FM signals over a broad frequency range of 2 MHz to 3.2 GHz, this option provides precision measurements of modulation rate, depth, and carrier power. By integrating these capabilities directly into the spectrum analyzer, engineers can save time and resources, avoiding the need for additional demodulation hardware or complex setups.

For example, consider an RF engineer developing an FM transmitter for a communication system. Without the AMA option, they would need to manually measure carrier power, modulation depth, and frequency offset using separate instruments or painstaking manual calculations. With the AMA option, these parameters are calculated and displayed instantly, providing immediate feedback on signal performance. This streamlined workflow not only improves productivity but also ensures precise tuning and compliance with modulation specifications, saving the engineer both time and effort while enhancing product quality.
