How DPOs Work
Unlike DSOs that have long dead times between
acquisitions, Digital Phosphor Oscilloscopes
(DPOs) continuously acquire waveforms at rates
comparable to analog oscilloscopes. DPOs
continuously overlay the acquired information
into a three-dimensional database that is
updated on the display 30 times per second. For
each pixel in the display, the intensity (or color)
of the pixel is proportional to the number of
actual samples that the pixel represents.

signal and a Clock signal. The specified setup and hold

combination of up to three other channels is true.
To Use A (Main) and B (Delayed) Triggers
Y ou can use the A Event (Main) trigger alone or combine it with the B Event (Delayed) trigger to capture more complex signals.
Set the A trigger type and source in the
A Event (Main) tab of the trigger control
window.
Choose a function in the A→B Sequence tab of
the trigger control window.
Set the trigger delay time or the number
of B events, as appropriate.
Set the B trigger characteristics in the B Event

More Operating Tips:
H B-trigger delay time and horizontal delay time are independent functions. When
you establish a trigger condition using either the A trigger alone or the A and B
triggers together, you can also use horizontal delay to delay the acquisition by an
additional amount.
H When using the B trigger, the A trigger can be any of the following types: Edge,
Glitch, or Width. The B trigger type is always Edge type.
To Take Measurements with Cursors
