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.
