RIGOL Chapter 6 Operations and Measurements
6-38 MSO8000 User's Guide
Press Mode to select the measurement mode to "Normal" or
"Precision".
Normal: executes measurement of up to 1 Mpts.
Precision: executes measurement of up to 500 Mpts, improving the
resolution of measurement results. Note, in this mode, the refresh rate
of the waveforms may be reduced.
Note: When the memory depth is less than or equal to 1K points or the
"High Res" mode is opened, the "Precision" measurement mode will
automatically switch to the "Normal" measurement mode.
Press Type to select "Threshold", "Range", or "Amp Method".
Select "Threshold", and then make the following settings:
--Press Source to select the desired channel for measurement
(CH1-CH4 or Math1-Math4).
--Press Upper to select "Upper(% )" or "Upper(Abs)" first, and then
press the key to set the upper limit of the measurement. For details,
refer to descriptions in "
Parameter Setting Method". When the
upper limit is set to be smaller than or equal to the current middle value,
a prompt message "Set at lower limit" is displayed. Then, the
oscilloscope will automatically adjust the upper limit and make it
greater than the middle value. By default, it is 90% .
--Press Mid to select "Mid(% )" or "Mid(Abs)" f irst, and then press the
key to set the middle value of the measurement. For details, refer to
descriptions in "
Parameter Setting Method". The middle value is
limited by the settings of the upper limit and lower limit. By default, it is
50% .
--Press Low er to select "Lower(% )" or "Lower(Abs)" f irst, and then
press the key to set the lower limit of the measurement. For details,
refer to descriptions in "
Parameter Setting Method". When the
lower limit is set to be greater than or equal to the current middle value,
a prompt message "Set at upper limit" is displayed. Then, the
oscilloscope will automatically adjust the lower limit and make it
smaller than the middle value. By default, it is 10% .
--Press Default, and then the upper value, middle value, and lower
value will be restored to the defaults.
Select "Range", and then press Region to select "Main", "Zoom", or
"Cursor".
--Main: indicates that the measurement range is within the main time
base region.
--Zoom: indicates that the measurement range is within the zoomed
time base region. Note: Only when you enable the delayed sweep
function f irst, can "Zoom" be enabled.
--Cursor: when you select it, two cursors will be displayed on the
screen. At this time, press CursorA and CursorB respectively and
then rotate the multifunction knob
to adjust the positions of the
two cursors to determine the measurement range. Also, you can press
CursorAB and then rotate the multifunction knob to adjust the
