Note that the "Measurement" icon and the MEAS key always configure and start a new
default measurement for the selected waveform. Any previous configurations for that
measurement are overwritten. If no measurement is currently running, pressing the
MEAS key has the same effect. To recall a previously configured and disabled measure-
ment, select the "Meas > Setup" menu item.
5.2.2.2 Taking a Default Measurement
When you tap the "Measurement" icon on the toolbar or press the MEAS key, the default
measurement is started:
●
amplitude measurement for time domain waveforms
●
channel power measurement for frequency domain waveforms
To start a default measurement with the toolbar icon
1. Select the waveform for which you want to perform the measurement.
2. Tap the "Measurement" icon on the toolbar.
3. Tap the diagram with waveform, or draw a rectangle on the screen to define a gate
area for which the amplitude is measured.
The default measurement is enabled for the next available measurement configura-
tion. If a rectangle was drawn on the screen, the corresponding gate area is defined
to limit the measurement. The "Measurements" result box is displayed.
To start a default measurement with the MEAS key
1. Select the waveform on the screen.
2. Press the MEAS key.
The default measurement is enabled for the next available measurement configura-
tion, using the selected waveform as the source. The "Measurements" result box is
displayed.
5.2.2.3 Configuring Measurements
Up to eight automatic measurements can be configured and performed simultaneously
with the data acquisition.
Spectrum measurements require an FFT math waveform as measurement source. His-
togram measurements require a histogram as source.
1. If a measurement was already started with the toolbar icon or MEAS key, tap the
icon in the result box, or press the MEAS key to display the "Measurements"
dialog box.
Otherwise, from the "Meas" menu, select "Setup".
