Parameter Set Up
Use the P
x
dialogs to define a new set of measurement parameters ("My Measure").
You may also define parameters using
or the
1. From the menu bar, choose
Measure > Measure Setup
. On the Measure dialog, select
Show
Table
to display the readout on screen.
To quickly reopen the Measure Setup dialog, touch any cell of the Measure readout table.
2. Choose Measure Mode
My Measure
.
3. Open the
P
x
tab
of an unused location (or one that you want to change).
4. Check
On
to enable the parameter and add it to the measurement readout table.
5. Select the Type
Measure On Waveforms
.
6. Touch
Source1
and select the channel, math trace, memory trace, or other waveform to be
measured.
7. Touch the
Measure
field and select the measurement from the pop-up menu.
8. Enter the measurement
Level
and
Type
(percent or absolute) when it appears on the parameter
subdialogs (e.g., for @Level parameters).
9. For certain time-based measurements, choose to measure on the positive, negative, or both
Slope
(s). For two-input parameters, such as Dtime@level, you can specify the slope for each
input, as well as the level and type.
10. Make any further selections on the subdialogs that appear after your Measure selection. These
are explained on the dialog and are necessary to fully define the selected measurement.
11. Optionally, turn on
, or use the parameter subdialogs to:
l
measurements (limit the horizontal scope of the measurement)
l
Qualify measurements (
only measurements that meet additional conditions)
Gating Measurements
By using gates, you can narrow the span of the waveform on which to perform tests and
measurements, allowing you to focus on the area of greatest interest. For example, if you "gate" five
rising edges of the waveform, rise time calculations are performed only on the five pulses bounded by
the gate posts.
