Restriction:
The frequency cannot be selected.
To set numerical value by using the Jog and Shuttle
controls, press the
VALUE key.
The selected window is not displayed in the pre-trigger
setting.
Example for Voltage Drop Trigger
For a signal such as shown in the illustration (frequency 50 Hz), the
following applies:
V max. < 1.000 V (RMS < 707.1 mV rms)
To perform trigger measurement under the above conditions, make the
following setting.
Voltage drop f = 50 Hz Level = 1.000 V (707.1 mV rms)
If the conditions are met already when measurement is started, triggering
does not occur. Triggering only occurs if the conditions are removed and
then met again.
