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:
l
Standard parameters for measuring amplitude and time
l
Custom parameters you configure
l
Specialized parameters for applications such as pass/fail testing or serial data decode (if you have
those options installed)
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 Gate right-hand dialog.
For Standard Horizontal or Standard Vertical parameters, all parameters share the same gate.
Touch the Default button to return gates to the width of the trace.
Level and Slope
For several time-based measurements, you can choose to begin the measurement on positive, negative,
or both slopes. For two-input parameters, such as Dtime@level, you can specify the slope for each input,
as well as the level and type (percent or absolute).
Make Level selection on the right-hand Level dialog when it appears.
