After the Measure Histogram function is enabled, please refer to
Measurement Item
to add new measurement parameter. The new parameter will be
used as the measurement item. In the "Result" sidebar, you can also click or tap the
label of the added measurement parameter (e.g. "Vpp" and "Vmin") to change the
measurement item.
Indicator
Click or tap the Indicator on/off switch to enable or disable the indicator.
If enabled, one or more cursors will be displayed on the screen. Before enabling the
indicator, you need to enable at least one auto measurement parameter and the
number of cursors will change with the measurement parameter enabled.
TIP
When no measurement parameter is selected or there is no source input, the indicator is not
available. The indicator changes when the waveform is expanded or compressed horizontally.
Measurement Threshold
• First, select % or Abs as the display type.
• Click or tap the drop-down button of Source to select the desired channel. You
can select from CH1-CH4, D0-D15, or Math1-Math4. D0-D15 are available only
when the digital channel probe is connected.
• Click or tap the input field of Upper and use the pop-up numeric keypad to set
the upper limit of the measurement or use the corresponding multipurpose
knob to set the value. 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%. The default absolute value
varies with the vertical setting of the channel.
• Click or tap the input field of Mid and use the pop-up numeric keypad to set the
middle value of the measurement or use the corresponding multipurpose knob
to set the value. The middle value is limited by the settings of the upper limit
and lower limit. By default, it is 50%. The default absolute value varies with the
vertical setting of the channel.
• Click or tap the input field of Lower and use the pop-up numeric keypad to set
the lower limit of the measurement or use the corresponding multipurpose knob
to set the value. 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%. The default absolute value varies with the
vertical setting of the channel.
• Click or tap Default to return the upper, middle, and lower limits to their default
values.
