Display an Unknown Signal with Autoset or AutoRange™
The Autoset and AutoRange™ features let the instrument display complex,
unknown signals automatically. The Autoset function provides a one time
setup of the vertical, horizontal and trigger systems of the instrument. The
Autoranging function provides continuous auto setup of vertical, horizontal, and
trigger systems that track signal changes. When the signal changes, the setup is
automatically adjusted to maintain the best display result. This feature is useful
for quickly checking several signals.
Enable Autoset
There are several steps to enabling the Autoset feature. The first involves setting
the Autoset parameters as follows:
1. Press the Utility button.
2. Select Options.
3. Check that the Auto Set Adjust menu item is highlighted black, and then
press Enter.
4. Select the frequency range:
If the frequency range is set to 15 Hz and up, the Autoset function responds
more quickly at this range because the instrument is instructed not to analyze
low frequency signal components.
