Abstract
An oscilloscope has an additional vertical display mode to enable the display of the trigger signal, activating the sweep generating circuit, simultaneously with the display of the normal vertical channels. The triggering source, level, slope and subtle time relationships can be verified and examined continuously and concurrently with the measurements upon the normal vertical channels. The displayed trigger signal is in correct time relationship with the normal vertical channels and the trigger level threshold is identified.
