The automatic measurement of time parameters

The oscilloscope provides time parameters auto-measurements include Frequency,

Period, Rise Time, Fall Time, +Width, -Width, Delay 1→2

, Delay 1→2 , Phas 1

→2

, Phas 1→2 , +Duty and -Duty. The following figure shows a pulse with some

of the time measurement points.

Figure 2- 132 Time parameters

Rise Time: Time that the leading edge of the first pulse in the waveform takes to

rise from 10% to 90% of its amplitude.

Fall Time: Time that the falling edge of the first pulse in the waveform takes to fall

from 90% to 10% of its amplitude.

+Width: The width of the first positive pulse in 50% amplitude points.

-Width: The width of the first negative pulse in the 50% amplitude points.

Delay 1→2

: The delay between the two channels at the rising edge.

Delay 1→2

: The delay between the two channels at the falling edge.

Phas 1→2

: The phase deviation between the two channels at the rising edge.

Phas 1→2

: The phase deviation between the two channels at the falling edge.

+Duty: +Duty Cycle, defined as +Width/Period

-Duty: -Duty Cycle, defined as -Width/Period
