RIGOL Chapter 5 To Trigger the Oscilloscope

5-20 MSO2000A/DS2000A User’s Guide

Slope Trigger

Trigger on the positive or negative slope which satisfies the specified condition.

Trigger Type:

Press Type, rotate to select “Slope” and press down . At this point, the

trigger setting information is displayed at the upper right corner of the screen. For

example,

. The trigger type is slope trigger; the trigger source is

CH1; the difference between the upper limit of trigger level and the lower limit of

trigger level is 1.24 V.

Source Selection:

Press Source to switch the signal source list between CH1 and CH2. For the details,

please refer to the introduction in “

Trigger Source”. The current trigger source is

displayed at the upper right corner of the screen.

Note: Select channel with signal input as trigger source to obtain stable trigger.

Slope Condition:

In this oscilloscope, positive slope time is defined as the time difference between the

two crossing points of trigger level line A and B with the rising edge; negative slope

time is defined as the time difference between the two crossing points of trigger level

line A and B with the falling edge as shown in the figure below.

Figure 5-6 Positive Slope Time/Negative Slope Time

Press When to select the desired slope condition.

 : trigger when the positive slope time of the input signal is greater than

the specified time.



: trigger when the positive slope time of the input signal is lower than the

specified time.



: trigger when the positive slope time of the input signal is greater than

the specified lower limit of time and lower than the specified upper limit of time.
