Main / Delayed menu
Main is the normal viewing mode for the display. Delayed mode expands the main view.
In Delayed mode the top half of the display shows the main sweep and the bottom half shows the
delayed sweep. The delayed sweep is a magnified portion of the main sweep. The magnified
portion is adjustable using the Horizontal controls.
Single and Run Control
The continuous Run mode uses half the memory to acquire data and the other half is
used to process the previous acquisition.
Single acquisition mode uses twice the memory as the Run acquisition mode. The
increase in memory allows for a high sampling rate at slower sweep speeds. Single acquisition
will acquire data with the longest record. So use the Single acquisition mode for maximum
sampling rate and memory depth. Set the trigger mode to Normal and the trigger level high
enough so the desired event will trigger the acquisition and not a low level event. The scope will
otherwise immediately trigger.
Acquire Modes
Normal > Best for most waveforms. No averaging. Default setting.
> At slow speeds extra samples are discarded.
Peak Detect > Best for capturing narrow pulses.
> At slow speeds extra samples are kept to capture narrow pulses.
> Displays pulses as narrow as 500 pS.
High Resolution > At slow speeds extra samples are averaged to produce a point.
> Limits the scopes real – time bandwidth (acts as a low – pass filter).
Average > Averages acquisitions to reduces noise.
> Bandwidth and rise time are not reduced.
