RIGOL Chapter 5 To Trigger the Oscilloscope
5-10 DS1000Z User Guide
Slope Trigger
In slope trigger, the oscilloscope triggers on the positive or negative slope of the
specified time. This trigger mode is applicable to ramp and triangle waveforms.
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 400 mV.
Source Selection:
Press Source to switch the signal source and select CH1-CH4. 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 5-4 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.
: trigger when the negative slope time of the input signal is greater than
the specified time.
: trigger when the negative slope time of the input signal is lower than
the specified time.
