The system makes use of software-controlled filters allowing measurements over a wider dynamic range without interference from adjacent frequencies. The user is also able to change the character of the filters from standard ANSI CLASS III triple tuned filters to filters with sharper skirts (better than CLASS III). These sharper filters allow the user to measure over a larger dynamic range without interference from adjoining frequencies.
