(2) Condition
a. ＞：It will be generated when the slope time of the trigger signal is greater than the setting slope
time, it can set the lower limit of time.
b. ＜：It will be generated when the slope time of the trigger signal is less than the setting slope
time, it can set the upper limit of time.
c. ≤≥：It will be generated when the slope time of the trigger signal is within the scope of setting
slope time, it can set the lower/upper limit of time.
Note：Slope time of trigger signal refers to the figure shown “slope time of rising/ falling edge”.
(3) Threshold
Threshold has three mode: low level, high level and high-low level. Press LEVEL knob to quickly
select the mode.
a. Lower level：The slope of the low threshold level can be adjusted with the LEVEL knob.
b. High level：The slope of the high threshold level can be adjusted with the LEVEL knob
c. High-low level：The slope of the high-low threshold level can be adjusted with the LEVEL knob
(4) The lower/upper limit of time
Set the time of slope, range can be set to 8ns ~ 10s.
Note: The formula for calculating the slew rate is
(High level threshold - Low level threshold) ÷ Time
For the set slew rate, the time here is the time setting value. For the slew rate of the trigger signal, the
time here refers to the time value between two intersection points where the high level, low level
intersect with the trigger signal.
7.6 Runt Trigger
The runt trigger is used to trigger a pulse that has crossed one trigger level but not the other.
In this oscilloscope, the positive runt pulse is the pulse that crosses the lower limit of the trigger level but
does not cross the upper limit of the trigger level; the negative runt pulse is the pulse that crosses the
upper limit of the trigger level but does not cross the lower limit of the trigger level, as shown in Figure 7-
3..
The runt trigger menu can set source, trigger coupling, trigger mode, polarity (positive, negative pulse),
runt condition (irrelevance, ＜, ＞,≤≥), time setting (the lower/upper limit of time), trigger level, etc.
