The settings are described in Chapter 5.4.2, "Mode settings", on page 150.
1. Open "Menu" > "Acquire" > "Mode" tab.
2. To configure the waveform-specific acquisition settings, enable "Multi waveform".
Activate the waveforms "W1"/"W2"/"W3" you need.
You can set up and display up to three waveforms per channel.
3. Select the "Mode" - for example, Peak detect or High res.
4. Select the "Wfm Arithmetic" - for example, Average or Envelope.
The instrument precludes incompatible combinations, like "Peak detect" with "Aver-
age".
5. If "Wfm Arithmetic"="Average" is selected for a waveform, enter the "Average
count", that is the number of waveforms used for average calculation.
6. Set the aritmetic reset condition for the average and envelope calculation:
a) If "Arithmetic Reset > Mode"="Time" is selected, enter the "Time".
b) If "Arithmetic Reset > Mode"="Waveforms" is selected, enter the "Count".
5.9.5 Starting and stopping acquisition
You can control the acquisition in two ways:
●
Running continuous acquisition until you stop it.
●
Running one acquisition or a given number of acquisitions.
If "Envelope" or "Average" is selected in the "Acquisition" tab, one acquisition
means a cycle containing as many acquired waveforms as required to satisfy the
reset conditions.
Prerequisites:
●
Probes are connected.
●
Vertical and horizontal settings are adjusted.
●
Triggering is set.
●
Channels to be acquired are turned on.
To start and stop continuous acquisition
1. Check if the trigger mode is set to "Norm". The trigger mode is shown in the trigger
label in the upper right corner of the screen.
If not, press the trigger [Mode] key on the front panel to toggle the setting.
2. Press the [Run Stop] key to start acquisition.
The acquisition starts if a trigger occurs.
3. To stop , press the [Run Stop] key again.
The acquisition stops immediately.
