TRACE STORAGE
The digital mode offers a set of powerful features. One of the most important
advantages is that you can store one or more traces in memory or on screen.
- Press the RUN/STOP key to stop the signal acquisition and freeze the
display on the screen.
The trace is frozen and stays on the screen. Observe that the signal stays stored
even when you remove the probe.
Now the instrument has been STOPped, and most keys have been disabled. The
only keys that continue to function are those directly related to display functions.
This includes trace shift using the POS control. All measurement functions are still
operable.
A frozen trace can be used for comparisons with other traces, mathematics,
cursor measurements, automatic measurements and more.
The RUN/STOP key is used to end the STOP mode and start the aquisition again.
- Press the RUN/STOP key.
This starts the acquisition again so that the actual input signal is displayed. You
can use the RUN/STOP key at any time.
RUNNING
NOTE: The following section explains the basic functions regardless of
operating mode. The oscilloscope will react almost identically in either
mode. Where necessary, different behavior will be explained.
