| Features |
 Compact, lightweight 1×1.4DIN enclosure easily mounted into rack.
Dedicated for comparator, easy to handle.
Compatible to Ethernet. Central control by a personal computer.
Effortless operations through touch panel interface.
With the utility software(provided free), files can be transferred between a PC and the AD-3552 FFT Comparators through Ethernet. |

| 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. |
