2. Select the "Enhancement".
If "Interpolated time" is set, select also the "Interpolation mode".
Enhancement affects all waveforms of all channels. The instrument uses enhance-
ment settings if the "ADC sample rate" is less than the "Sample rate"; otherwise these
settings are ignored.
3. To configure the waveform-specific acquisition settings, select the "Channel" tab and
activate the waveform.
You can set up and display up to three waveforms per channel.
4. Select the "Decimation" - for example, Peak detect or High res.
5. Select the "Wfm Arithmetic" - for example, Average or Envelope.
The instrument precludes incompatible combinations, like "Peak detect" with "Aver-
age".
6. If "Average" is selected for a waveform, enter the "Average count", that is the number
of waveforms used for average calculation.
7. Set the reset condition for the average and envelope calculation:
a) If "Time" is selected, enter the "Reset time".
b) If "Waveforms" is selected, enter the "Reset count".
2.2.4 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 con-
ditions.
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 "Normal". The trigger mode is shown in the trigger
label in the upper right edge of the screen.
If not, press the AUTO/NORMAL key on the front panel to toggle the setting.
2. Press the RUN CONT key to start acquisition.
The acquisition starts if a trigger occurs.
3. To stop , press the RUN CONT key again.
The acquisition stops immediately.
