Marker Mode
Provides display marker control with a horizontal soft key menu. Markers can be turned off or on with a
choice of numeric readout for the signal measurements as follows:
Delta V – The numeric reading shows the difference in amplitude between marker positions.
Delta T – The numeric reading shows the difference in time between marker positions.
1/DeltaT – The numeric reading shows the inverse of the time difference between markers which can be
used to determine the frequency of a repetitive waveform.
Absolute – The numeric reading shows the absolute amplitude at the marker position
Toggle Marker
Cycles through the available markers to select the active one (yellow) for positional adjustment on the
display. The active marker is moved with the Left/Right (◄►) keys
Trigger Mode
Submenu selections for the horizontal sweep trigger mode. The choices are as follows:
