RIGOL  Chapter 6 Operations and Measurements 
6-38  MSO7000/DS7000 User Guide 
➢  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. 
⚫  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". 
By default, it is 90%. 
--Press Mid to select "Mid(%)" or "Mid(Abs)" first, 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 Lower to select "Lower(%)" or "Lower(Abs)" first, and 
then press the key to set the lower limit of the measurement. For 
details, refer to descriptions in "Parameter Setting Method". 
Increasing the lower limit to the current middle value will 
automatically increase the middle value and upper limit to keep 
them higher than the lower limit. 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 first, 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 positions of the two cursors simultaneously. 
➢  Select "Amp Method", and then press Amp Method to select 
"Auto" or "Manual". This method affects the measurement method 
for the top and base values. If you select "Manual", you need to 
set the following parameters: 
--Press Top to select "Histogram" or "Max-Min". 
--Press Base to select "Histogram" or "Max-Min".
