The RANGERNeo 2  field strength meters offer compatibility with the VCM / ACM modulation schemes

RANGERNeo 2 field strength meters offer compatibility with the latest 16-APSK / 32-APSK constellation setups and VCM / ACM modulation schemes which are often used in satellite radio links, mainly for news gathering and video contribution purposes.

These constellations (16-APSK and 32-APSK, picture below) are widely used hand in hand with VCM (Variable Coding and Modulation) and ACM (Adaptative Coding and Modulation) schemes, allowing the operator to change the modulation parameters used in the same RF channel through time.
