Powerful Analysis Software |
|
When a single AD3551 FFT comparator is in use, a setup wizard allows easy setting of conditions. A setup wizard allows easy setting of conditions. The AD-3552 FFT Comparator has a built-in PC that features superior reliability and fast response. Setting judgment parameters for level, partial overall, octave band, total overall is practicable. (Block: 20 types, Shape: 1 type, Total overall: 1 type) Judgments under complex conditions can be delivered by combining comparator logic (AND, OR, NOT) Using a DI/DO board, the AD-3552 FFT Comparator can output judgment results and be controlled externally. |
