+Duty - Oscilloscope Automatic Measurement Type

A type of automatic measurements. Measures the first cycle waveform. Positive Duty Cycle is the ratio between positive pulse width (t) and period (T).

+Wid - Oscilloscope Automatic Measurement Type

A type of automatic measurements. +Wid measures the time between the first rising edge and the next falling edge at 50% level of the waveform.

-Duty - Oscilloscope Automatic Measurement Type

A type of automatic measurements. Measures the first cycle waveform. Negative Duty Cycle is the ratio between negative pulse width and period.

-Wid - Oscilloscope Automatic Measurement Type

A type of automatic measurements. -Wid measures the time between the first falling edge and the next rising edge at 50% level of the waveform.

Addition (+)
Addition is a mathematical function in digital oscilloscopes.

Afterglow is a gradual decrease in the brightness of oscillogram points on a scope display. Depending on the mode used brightness can stay steady or reduce with a specified speed.

Aliasing
When you change horizontal sweep on a digital oscilloscope you can see the waveform changing of the same signal on different horizontal sweeps. It’s important to take into consideration the fact that you work with a digital oscilloscope and it digitizes a signal with different sampling rate depending on the horizontal sweep chosen, and afterwards it connects the digitized points with a smooth line (interpolates them), restores the real signal waveform.

Alternative trigger
Two-channeled alternative triggering for simultaneous observation of two nonsynchronized signals.

The difference between maximum and minimum signal values.

Area - Oscilloscope Automatic Measurement Type
One of the auto measurement types in digital oscilloscopes, relating to a derivative measurement type of amplitude and time, is the definition of an area under the waveform curve.
