Key Features
The key feature of ВСН-АТ meter is the wideband digital frequency generator (DDS) to ensure such unique advantages as:
- Ability to analyze a wide frequency range as opposed to one or few frequencies (typically up to four frequencies maximum)
- Frequency output is stabilized by crystal oscillator and has virtually zero dependence on the ambient temperature
- Automatic statistical-analysis based on Fourier transformation
- ВСН-АТ electronic hardware compatibility with water-cut meter from other vendors
