To Use the Screen Interface
You can control all oscilloscope functions except the power switch using only the screen interface.
Choose the Toolbar
Touch a button in the toolbar to display a
control window at the bottom of the displ ay.
Touch a screen control to change a setting.
Touch a numerical control to assign that control
to a multipurpose knob. Turn the mul tipurpose
knob to adjust the parameter value.
Touch here to

Choose the Menu Bar
Use some menu items to
display a control window at the
bottom or side of the display.
Use some menu items to
directly change settings.
Touch here to close a
control window.
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 Display a Waveform
Attach a probe to CH 1 and connect the probe
to your signal.

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

More Operating Tips:
H You can use Zoom and Horizontal Delay together to magnify a delayed
acquisition.
H Toggle 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.
To Use Fast Acquisition (CSA7000 and TDS7000 Series only)
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.
Increasing intensity can make less-frequently
acquired points brighter in the display.

Horiz/Acq menu.
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.

More Operating Tips:
H Choose one of the color grading palettes in the Display Colors control window to
see different sample densities represented in different colors.
H Turn
AutoBright on in the Display Appearance control window. When you use
AutoBright, the displayed waveforms remain visible even at low trigger repetition
rates.
To Choose an Acquisition Mode
Select Horizontal/Acquisition Setup... in
the Horiz/Acq menu or touch the Horiz
button; then open the Acquisition tab.
Select an acquisition mode in the
horizontal/acquisition control window.
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.

consecutive acquisition intervals.
Hi Res mode calculates the average of all
the samples for each acquisition interval.
Envelope mode finds highest and lowest record
points over many acquisitions. Envelope uses
