Touch a screen control to change a setting.
Touch here to change to
toolbar operation.
Choose the Menu Bar
Choose the Toolbar
Touch a button in the toolbar to display a
control window at the bottom of the display.
Use some menu items to
display a control window at the
bottom or side of the display.
Touch here to
change to menu bar
operation.

Adjust VERTICAL and HORIZONTAL
POSITION and SCALE if necessary to
optimize the display.

To See More Waveform Detail
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 detail.

Then select a zoom mode from the
drop-down list to magnify the highlighted
waveform segment.
4
Use Horizontal Delay
Adjust the delay time with the horizontal
POSITION control, or enter the delay time
in the control window.
2
Adjust the horizontal SCALE to acquire
the detail you need around the delay
expansion point.
3
Use Zoom
Push the ZOOM button to display a
zoom graticule. 1
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 the actual acquired waveform. You can
select and lock together waveforms, and then scroll them automatically.
Use horizontal DELAY to acquire waveform detail in a region that is separated from
the trigger location by a significant interval of time.
Delay time
Trigger point Acquired waveform
Expansion point
Push the front-panel DELAY button.
HYou can use Zoom and Horizontal Delay together to magnify a delayed
acquisition.
HToggle Horizontal Delay on and off to quickly compare signal details at two
different areas of interest, one near the trigger location and the other centered at
the delay time.
More Operating Tips:
Main graticule Zoom graticule
Push the HORIZ button or the VERT button
to select the axis to magnify in the zoom
graticule. Use the multipurpose knobs to
adjust the position and magnification
factor of the zoomed waveform.

To Use Fast Acquisition (CSA7000 and TDS7000 Series only)
Push the front-panel FastAcq button.
Or select Fast Acquisitions in the
Horiz/Acq menu.
2
Adjust INTENSITY to optimize the intensity or
color grading for the signal being analyzed.
Increasing intensity can make less-frequently
acquired points brighter in the display.
HChoose one of the color grading palettes in the Display Colors control window to
see different sample densities represented in different colors.
Turn Fast Acquisition on to acquire up to 400,000 waveforms per second.
HTurn AutoBright on in the Display Appearance control window. When you use
AutoBright, the displayed waveforms remain visible even at low trigger repetition
rates.
More Operating Tips:
How DPOs Work
Analog Real Time sweeps
Digital Storage acquisitions
Digital Phosphor acquisitions
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.

For Average or Envelope acquisition modes,
touch the # of Wfms control and then set the
number of waveforms with the multipurpose
knob. You can also double-touch the control
and use the pop-up keypad.
To Choose an Acquisition Mode

Select Horizontal/Acquisition Setup... in
the Horiz/Acq menu or touch the Horiz
button; then open the Acquisition tab.

Envelope mode finds highest and lowest record
points over many acquisitions. Envelope uses
Peak Detect for each individual acquisition.
Sample mode retains one sampled point from
each acquisition interval.

Peak Detect mode uses the highest and
lowest of all the samples contained in two
consecutive acquisition intervals.
Hi Res mode calculates the average of all
the samples for each acquisition interval. Hi Res
Waveform Data Base mode takes an ensemble
of acquisitions that is best for accurate eye

Trigger on glitches narrower than the specified width or
ignore glitches narrower than the specified width.
Trigger on pulses that have widths between the range of
the two timers or outside the range of the two timers.
Trigger on a pulse that enters the transition region from
one side but does not leave the region from the other side.
Trigger when a signal does not make a transition for a
specified length of time.
Trigger when a logic signal spends more time or less time
in the transition region than a specified amount of time.
Trigger on violations of setup or hold time between a Data
signal and a Clock signal. The specified setup and hold
times can be positive or negative values.
Trigger when a Boolean combination of up to four
channels becomes true. Trigger immediately or only after
the combination is true for a specified time duration.
Trigger on transition of one channel when a Boolean
combination of up to three other channels is true.

HB-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.
HWhen 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.
More Operating Tips:
The A trigger arms the oscilloscope.
Posttrigger acquisition starts on nth B event.
The A trigger arms the oscilloscope.
Posttrigger acquisition starts on the first B
edge after the trigger delay time.
