The automatic measurement of time parameters

The DS1000 series oscilloscopes provide time parameters auto-measurements

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

Delay 1→2

, +Duty and -Duty.

Figure 2-118 shows a pulse with some of the time measurement points.

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.

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

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