Dx Amplifier

Dx Amplifier is used to amplify the output voltage of the Dx vacuum transducer.

The sensitivity of the Dx vacuum transducer from the USB Autoscope Lite is not sufficient to measure the vacuum pulsations in the intake manifold of a running engine. To increase the sensitivity of the Dx vacuum transducer, its output voltage can be amplified using the Dx Amplifier.

On the vacuum pulsation waveforms in the intake manifold with the engine running, you can find specific points that indicate the points when the engine pistons are at TDC, points where the intake valves open, and points where the exhaust valves close.

To measure the characteristics of these events in degrees of the crankshaft rotation angles, a special feature has been added to the USB Oscilloscope program in the form of a measuring panel "Dx Panel".
