To See More Waveform Detail
Use Zoom Use the Zoom function to magnify an acquisition vertically, horizontally, or in both
waveform dimensions. SCALE or POSITION changes you make to the Zoom graticule
affect only the display, not the actual waveform that is acquired.
Push the ZOOM button to split the 1
screen and add a zoom graticule.
Push the HORIZ button or the VERT button to 2
select the axis you want to magnify in the zoom Main graticule Zoom graticule
graticule. Use the multipurpose knobs to adjust
scale and position of the magnified waveform.
You can also set up a zoom graticule 3
from the screen interface. Click and drag
across the segment of the waveform that
you want to see in greater detail.
Then select Zoom from the drop-down list to 4
magnify the highlighted waveform segment.
Use Horizontal Delay Use horizontal DELAY to acquire waveform detail in a region that is separated from
the trigger location by a significant interval of time.
Trigger point
Acquired waveform
Delay time
Expansion point
Push the front-panel DELAY button. 1
Adjust the delay time with the horizontal 2
POSITION control, or enter the delay time
in the control window.
Adjust the horizontal SCALE to acquire 3
the detail you need around the delay
expansion point.
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
Turn Fast Acquisition on to acquire up to 100,000 waveforms per second.
Push the front-panel FastAcq button. 1
Or select Fast Acquisitions in the
Horiz/Acq menu.
Adjust INTENSITY to optimize the intensity or 2
color grading for the signal you want to analyze.
Increasing intensity can make less-frequently
acquired points brighter in the display.
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.

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 Acquisition Mode... in the 1
Horiz/Acq menu.
Or click the Horiz button, and then select
an acquisition mode in the
horizontal/acquisition control window.
For Average or Envelope acquisition modes, 2
click the # of Wfms control and then set the
number of waveforms with the multipurpose
knob. You can also double-click the control and
use the pop-up keypad.

To Select a Trigger
Select the EDGE trigger type and then set the
source, coupling, slope and mode with these
front-panel controls. Push ADVANCED to select
one of the other trigger types.
You can also select a trigger type in the
Trigger menu.
Or click the Trig button and then select a
trigger type in the trigger control window
that is displayed.
Trigger Selections
Trigger type Levels Timers Trigger conditions
Edge Single level None Trigger on rising or falling edge, as defined by slope
control. Coupling choices are DC, AC, AC LF Reject, AC
HF Reject, and Noise Reject.
Video Single level None Trigger on NTSC, PAL, SECAM, Analog HDTV, and
Custom video formats.
Glitch Single level One to specify glitch Trigger on glitches narrower than the specified width or
width ignore glitches narrower than the specified width.
Width Single level Two to specify minimum Trigger on pulses that have widths between the range of
and maximum pulse the two timers or outside the range of the two timers.
widths
Runt Two levels to define the One to specify an Trigger on a pulse that enters the transition region from
logic transition region optional minimum one side but does not leave the region from the other side.
runt-pulse duration Pulses can be qualified with the logical states of other
channels (4-channel models only).
Window Two levels to define One to specify an Trigger when a signal violates either upper or lower
signal transition region optional minimum boundaries set outside the normal range of the signal.
violation width Events can be qualified with the logical states of other
channels (4-channel models only).
Timeout Single level One to specify time-out Trigger when a signal does not make a transition for a
time specified length of time.
Transition Two levels to define the One to specify transition Trigger when a logic signal spends more time or less time
logic transition region time in the transition region than a specified amount of time.
Setup/Hold Independent levels for One to specify setup Trigger on violations of setup or hold time between a Data
Data and Clock time and one to specify signal and a Clock signal. The specified setup and hold
hold time times can be positive or negative values.
Pattern Independent levels for One to specify pattern Trigger when a Boolean combination of up to four
each channel duration channels becomes true. Trigger immediately or only after
the combination is true for a specified time duration.
State Independent levels for None Trigger on transition of one channel when a Boolean
each channel combination of up to three other channels is true.
To Use A (Main) and B (Delayed) Triggers
You 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 1
A Event (Main) tab of the trigger control
window.
Choose a function in the AB Sequence tab of 2
the trigger control window.
Set the trigger delay time or the number 3
of B events, as appropriate.
Set the B trigger characteristics in the B Event 4
(Delayed) 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 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
Push the front-panel CURSORS button. 1
Select the waveform you want to measure and 2
a cursor type in the cursor control window.
Or you can activate cursors on the selected
waveform directly in the Cursor menu.
Place cursors with the multipurpose 3
knobs or enter the cursor locations
numerically.
If you choose split cursors to take 4
measurements between waveforms,
select the source for each cursor. T1: 356.4 ms
T2: 352.5 ms
DT: 3.92 ms
1/DT: 255 Hz
V1: 5.120 V
V2: 4.886 V
DV: 234 mV
DV/DT: 59.7 V/s
Read cursor measurement 5
results in the display.
Other Cursor Measurement Tips:
H You can set the cursors to move together in tandem if you choose the Tracking
cursor mode. The cursors move independently if you choose the Independent
cursor mode.
H If you use the zoom graticule, you can place a cursor directly on a specific
waveform point to take precision measurements.
H You can also move cursors by dragging them to a new position.
To Take Automated Measurements
Click the Meas button, and then select up to
eight measurements using the measurement
control window.
