Chapter 5 To Trigger the Oscilloscope RIGOL
DS1000Z User Guide 5-11
: trigger when the negative slope time of the input signal is greater than
the specified lower limit of time and lower than the specified upper limit of time.
Time Setting:
When the Slope Condition is set to
, , or ,
press Time and use to input the desired value. The range available is from 8
ns to 10 s.
When the Slope Condition is set to or , press Upper Limit
and Lower Limit and use to input the desired values respectively. The
range of time upper limit is from 16 ns to 10 s. The range of the time lower limit
is from 8 ns to 9.99 s.
Note: The time lower limit must be lower than the upper limit.
Vertical Window and Trigger Level:
After the trigger condition setting is completed, adjust the trigger level using
TRIGGER
LEVEL to correctly trigger the signal and obtain stable waveform. The
adjustment mode of the trigger level is different when different vertical window is
selected in slope trigger. Press Vertical and use to select the desired vertical
window or press down Vertical continuously to switch the vertical window. You can
choose to only adjust the upper limit, the lower limit or both of them.
: only adjust the upper limit of the trigger level. During the adjustment,
"UP Level" and "Slew Rate" change accordingly but "Low Level" remains
unchanged.
: only adjust the lower limit of the trigger level. During the adjustment,
"Low Level" and "Slew Rate" change accordingly but "UP Level" remains
unchanged.
: adjust the upper and lower limits of the trigger level at the same time.
During the adjustment, "UP Level" and "Low Level" change accordingly but
"Slew Rate" remains unchanged.
When the Slope Condition is set to
, , , or , the
current trigger level and slew rate will be displayed at the lower left corner of the
screen, as shown in figure 5-5 (a). The formula of slew rate is:
UpLevel - LowLevel
SlewRate=

When the Slope Condition is set to or , the current trigger level
and slew rate range will be displayed at the lower left corner of the screen, as shown
in figure 5-5 (b). The formula of slew rate range is:
