HDO4000 High Definition Oscilloscope
Measure
Measurement parameters are tools that give you access to a wide range of waveform properties. Use
them to analyze many attributes of your waveform like rise-time, rms voltage, and peak-to-peak voltage,
for example.
The oscilloscope offers a selection of standard horizontal and vertical
measurement parameters
.
You can configure and display up to eight measurement parameters at once.
Measure Gate
By using gates, you can narrow the span of the waveform on which to perform parameter measurements,
allowing you to focus on the area of greatest interest. For example, if you "gate" five rising edges of the
waveform, the parameter calculations for rise time are performed only on the five pulses bounded by the
gate posts.
The default starting positions of the gate posts are 0 div and 10 div, which coincide with the left and right
ends of the grid. The gate, therefore, initially encloses the entire waveform.
The quickest way to set a gate is by dragging the gate posts located at the far left and right of the grid to
the desired positions.
You can refine this setting by specifying a position down to hundredths of a division in the
Gate Start
and
Stop
fields on the main Measure dialog dialog. All parameters share the same gate.
Touch the
Default
button to return gates to the width of the trace.
Level
All @Level parameters are measured at the same level. Level can only be set as a percentage and is only
available when an @Level parameter has been selected.
Set Up Measurement
To configure custom measurements to add to the table of parameter readouts:
1. From the menu bar, choose
Measure > Measure Setup
.
2. Touch the
Measure button
next to an unused
Px
location (or one that you want to change), then
choose the measurement from the pop-up window.
3. For each input required by the parameter, touch
Source
and select the channel, math trace, memory
trace, or other waveform to be measured.
4. Optionally,
set a measurement gate
by dragging the gate posts to reposition them.
5. Optionally, choose to display
Statistics
or
Histicons
in the measurements table.
6. Check
Show Table
to display the readout on screen.
