The Acmt Method Can Do Even More - Adash 4400 VA4 Pro User Manual

ADASH Ltd. Adash 4400 – VA4Pro
Next measurement uses the ACMT method. You see, it works. Long time signal contains required number of
pulses and the peak of each of them is captured. That is what we need.

The ACMT method can do even more

Short duration pulses have usually small amplitude. They are often modulated by speed frequency.
We use standard measurement and result is in the next picture.
You see only speed sine wave and no or small pulses, which are filtered by anti aliasing.
The standard ACMT is used in next picture. We used the ACMT together with band pass filtering which removes
the speed sine wave from the signal.
The all short-pulses are held and amplitude are modulated for better view.
This result is much better, because Y axe scale corresponds with real pulses amplitude, not with speed sine
wave amplitude.
