Automatic Trigger Options
The Trigger Menu has the settings for automatic triggering.
To change:
1. Press
T
to show the TRIGGER key labels.
Note
The TRIGGER key labels can differ depending on the latest trigger function used.
2. Press 4 to open the TRIGGER OPTIONS menu.
3. Use the cursor and

to open the AUTOMATIC TRIGGER menu.
If the frequency range of the automatic triggering is set to >15 Hz, the Connect-and-View
function responds more quickly. The response is quicker because the test tool is instructed
not to analyze low frequency signal components. However, when you measure frequencies
lower than 15 Hz, the test tool must be instructed to analyze low frequency components for
automatic triggering: 4
4. Use the cursor and
E
to select >1 Hz and return to the measurement screen.
