15.2.2 Scope Time-base and Trigger Tab
Use the Time-base and Trigger tab to select how much data to record and when to start (trigger) recording the
data. You can set length of recording in ms and the sampling frequency in Hz. The number of samples is a cal-
culated value displayed for reference.The trigger can be set to trigger immediately when you click Start Record-
ingor to trigger when a specified value for a given signal is reached. The default Time-base and Trigger view
specifies recording time, sampling frequency, and either an immediate trigger or a trigger based on a specified sig-
nal. Click the More button in this view to specify a given number of samples, sampling frequency, sampling inter-
val, and access additional trigger options.
In this tab, you can set length of recording in ms and the sampling frequency in Hz. The number of samples is a
calculated value displayed for reference. You can also choose the trigger source to be Immediate (triggers as
soon as you click the Start Recording button) or to be one of many predefined sources.
If you choose a source other than Immediate, you can set the level, position, and slope for the trigger value.
l Level sets the value of the source that triggers the recording to start.
l Position sets the amount of time that the scope displays before the trigger occurred.
l Slope sets whether the source data must pass the level value in a positive or negative direction.
An example of triggering is shown below:
