Use this mode to let the acquisition free-run in
the absence of a valid trigger; This mode allows
an untriggered, scanning waveform at 100
ms/div or slower time base settings.
Use this mode when you want to see only valid
triggered waveforms; when you use this mode,
the oscilloscope does not display a waveform
until after the first trigger.
When you want the oscilloscope to acquire a
single waveform, press the “SINGLE” button.
Enter the “Trigger Setup Menu” (See Table 3.16).
Table 3.16 – Trigger Setup Function Menu
Passes all components of the signal
Blocks DC components, attenuates
signals below 50 Hz.
Attenuates the high-frequency
components above 150 kHz.
Blocks the DC component, attenuates the
low-frequency components below 7 kHz.
Using the “universal” knob to adjust
holdoff time (sec), the holdoff value is
displayed.
Reset holdoff time to 100ns.
