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.

Or 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.
Push CH 1 if channel 1 is not
already displayed.
Push AUTOSET.

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 you want to magnify in the zoom
graticule. Use the multipurpose knobs to adjust
the zoomed waveform’s position and
magnification factor.
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 graticule 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
display dimensions.

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 Choose an Acquisition Mode
Select Acquisition Mode... in the
Horiz/Acq menu.
Or touch the
Horiz button, and then
select an acquisition mode in the
horizontal/acquisition control window.
For Average or Envelope acquisition modes,
touch the
#ofWfmscontrol and then set the
number of waveforms with the multipurpose
knob. You can also double-touch the control
and use the pop-up keypad.
How the Acquisition

Sample mode retains one sampled point from
each acquisition interval.

Waveform Data Base mode takes an ensemble
of acquisitions that is best for accurate eye
pattern measurements.
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.
Envelope mode finds highest and lowest record
points over many acquisitions. Envelope uses
Peak Detect for each individual acquisition.
Average mode calculates the average value for
each record point over many acquisitions.
Average uses Sample mode for each individual
acquisition.

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.
