Delayed Scan
The Delayed Scan is a magnified portion of the main waveform window. Use Delayed
Scan to locate and horizontally expand part of the main waveform window for a more
detailed (higher horizontal resolution) analysis of signal. The Delayed Scan time base
setting cannot be set slower than the Main time base setting.
Press MENU→Delayed→ON, or press horizontal
knob to turn on delayed
scan function. See the waveform below.
Figure 2-36 Delayed scan windows
The screen will be split into two parts.
The upper half displays the main waveform window and the lower half displays an
expanded portion of the main waveform window. This expanded portion of the main
window is called the Delayed Scan window. Two blocks shaded at the upper half; the
un-shaded portion is expanded in the lower half. The horizontal
and
knobs control the size and position of the Delayed Scan. The value at top
of the screen is the main time base and the value on the center bottom means the
Delayed Scan time base.
