Setting The Delay Time For A Waveform - Tektronix TDS1000B Series Operator's Manual

After you set up the oscilloscope for HORIZONTAL controls,
you can perform various procedures, such as setting the
delay time for a waveform.

Setting the Delay Time for a Waveform

You can set the oscilloscope to display a waveform relative
to the trigger point in time. This interval between the trigger
point and the displayed waveform is known as the delay
time. Setting the delay time for a displayed waveform allows
you to see a detailed view of the waveform both before and
after the trigger.
This delay time capability is important when the signal detail
of interest is delayed in time from the trigger, such as in a
disk drive system. In this case, the trigger typically happens
once per revolution on a track of data. This track can have
literally millions of bits of information to be analyzed. Delay
time allows the acquisition to be delayed to the details of
interest.
