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.
Figure 2-33 Delayed Scan windows
The following steps show you how to use Delayed Scan.
1. Connect a signal to the oscilloscope and obtain a stable display.
2. Press horizontal MENU→Delayed→ON or press horizontal knob to
enter Delayed Scan mode.
The screen splits 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 bottom of the screen is the main time base and the value
on the center bottom means the Delayed Scan time.
