1 Press the Thresholds softkey in the Quick Meas menu to set
analog channel measurement thresholds.
2 Press the Source softkey to select the analog channel source
for which you want to change measurement thresholds. Each
analog channel can be assigned unique threshold values.

3 Press the Type softkey to set the measurement threshold to %
(percentage of Top and Base value) or to Absolute (absolute
value.)
• Percentage thresholds can be set from 5% to 95%.
• The units for absolute threshold for each channel is set in
the channel probe menu.
Absolute threshold hints
• Absolute thresholds are dependent on channel scaling, probe attenuation, and
probe units. Always set these values first before setting absolute thresholds.
• The minimum and maximum threshold values are limited to on-screen values.
• If any of the absolute threshold values are above or below the minimum or
maximum waveform values, the measurement may not be valid.
4 Press the Lower softkey, then turn the Entry knob to set the
lower measurement threshold value.
Increasing the lower value beyond the set middle value will
automatically increase the middle value to be more than the
lower value. The default lower threshold is 10% or 800 mV.
If threshold Type is set to %, the lower threshold value can be
set from 5% to 93%.
5 Press the Middle softkey, then turn the Entry knob to set the
middle measurement threshold value.
