Slope Trigger
The slope trigger looks for a rising or falling transition from one level to another level in
greater than or less than a certain amount of time.
In the oscilloscope, positive slope time is defined as the time difference between the two
crossing points of trigger level line A and B with the positive edge as shown in the figure
below.
1. Press the Setup button on the front panel to enter the TRIGGER function menu.
2. Press the Type softkey; turn the Universal Knob to set select Slop and then push the
knob to confirm.
3. Press the Source softkey; turn the Universal Knob to select CH1 or CH2 as the
trigger source.
4. Press the Slop softkey; turn the Universal Knob to set select the desired trigger edge
(rising or falling), and then push down the knob to confirm. The current trigger slope is
displayed at the upper right corner of the screen.
5. Press Lower Upper softkey to select the Lower or Upper trigger level; then turn the
Trigger Level Knob to adjust the position. The trigger level values are displayed at
the upper right corner of the screen.
The lower trigger level cannot be upper than the upper trigger level. In the trigger state
message box, L1 means the upper trigger lever while L2 means the lower trigger level.
