More Operating Tips:
H Use the touch screen to control the oscilloscope when bench space is
unavailable, such as on a cart or in an equipment rack.
H Plug in a mouse and keyboard if you have the bench space to use them. You can
plug in a USB mouse or keyboard anytime, even while the oscilloscope is
running.
H Use the menu bar to access PC-related functions, such as Page Setup, Export,
and Copy.

To See More Waveform Detail
Use Zoom
Push the ZOOM button to display a

factor of the zoomed waveform.
You can also set up a zoom graticule
from the screen interface. First touch and
drag across the segment of the waveform
that you want to see in greater det ail.
Then select a zoom mode from the
drop-down list to magnify the highlighted
waveform segment.
Use Horizontal Delay
Use the Zoom function to magnify an acquisition vertically, horizontally, or in both
waveform dimensions. POSITION or FACTOR changes that you make to the Zoom
graticule affect only the zoom display, not t he actual acquired waveform. You can
select and lock together waveforms, and then scroll them automatically.

Turn Fast Acquisition on to acquire up to 400,000 waveforms per second.
Push the front-panel FastAcq button.
Or select
Adjust INTENSITY to optimize the intensity or
color grading for the signal being analyzed.

How DPOs Work
Digital Phosphor Oscilloscopes (DPOs)
continuously acquire waveforms at rates
comparable to analog oscilloscopes. In
Fast Acquisition mode, 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.

AutoBright, the displayed waveforms remain visible even at low trigger repetition
rates.

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.

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 al so 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, Width, or Timeout. The B trigger type is always Edge type.
