Trigger
User’s manual chapter 6, “Triggers”
There are three main categories of triggers: Edge/State triggers, Width triggers and Enhanced triggers.
Edge/State Triggers
Edge Trigger
Trigger occurs on the edge
(rising or falling) of a trigger
source. You can select a
trigger source* of
measurement input signal,
external trigger signal, or
commercial power supplied
from the instrument.
Edge(Qualified) Trigger
Trigger occurs on the
edge of a single trigger
source while each input
signal’s specified
conditions are true.
Edge(OR) Trigger
Trigger occurs if the edge
conditions of any one of
the multiple trigger sources
is true.
Width Triggers
Pulse Width Trigger Pulse(Qualified) Trigger
Trigger occurs if the Pulse
Width trigger conditions are
true while the status of
each input signal meets the
specified conditions.
Pulse State Trigger
Trigger occurs when a relationship between the time in
which the logical (state) condition of the specified input
signal becomes true or not true, and a specified time,
becomes true. You can also have state conditions be
judged on the edge of the specified input signal and
triggers activated on the timing of the edge.
Trigger occurs depending on
whether the conditions
became true or not for a
shorter or longer duration than
a reference time specified in
advance.
* A trigger source is a signal to which trigger activation conditions are applied.
** Supports software version 1.60 or later.
*** Supports software version 2.00 or later.
**** Supports software version 2.40 or later.
***** Supports software version 4.20 or later.
State Trigger
Trigger occurs when the
logical (state) condition of
the specified input signal is
true, or stops being true.
You can also have state
conditions be judged on
the edge of the specified
input signal and triggers
activated on the timing of
the edge.
Enhanced Triggers
TV Trigger
Trigger occurs on a video
signal.
Serial Trigger**
Trigger occurs on the
data pattern of a serial
bus signal.
Trigger occurs on the
data pattern of a LIN bus
signal.
Trigger occurs on the data
pattern of a UART bus
signal.
I2C Trigger**
Trigger occurs on the start
condition of an I2C bus
signal, address/data/
pattern, Non-ACK, general
call address, or start
byte/high speed mode.
SPI Trigger**
Trigger occurs on a data
or data pattern of an SPI
bus signal.
Trigger occurs on a pattern
of the SOF, error frame,
data frame/remote frame
of a CAN bus signal.

Introduction to Main Functions
History Memory
User’s manual Capture 11, “Displaying History Waveforms”
When measuring waveforms, numerical data is being loaded into the acquisition memory, and that data can be
viewed on the DL9000 screen as a waveform. When taking continuous measurements, even if you stop
measurement when you see an abnormal waveform, the waveform usually scrolls off the screen by the time
measurement stops, preventing you from viewing it carefully. But with the history memory function, you can display
past waveform data that has been loaded into the acquisition memory while measurement is stopped. Also, you can
search for waveforms within the history waveforms that meet specied waveform conditions. The following 6 search
conditions are available.
Conditions for searching for waveforms passing through (or not passing through) a specied search zone:
Waveform zone/rectangular zone/polygon waveform
Conditions for searching for waveforms that enter (or do not enter) a range of specied measured values.
Automatic measurement of waveform parameters/FFT-calculated values/XY waveform area
Searching the History Waveforms Using Rectangular Zone
History waveform
Selected Record No. 0 Selected Record No. –25
Specified search zone
Searches for waveforms
that pass through the
specified search zone.
Zooming a Waveform
User’s manual section 8.1, ”Zooming the Waveform”
You can expand (zoom) a displayed waveform along the time axis or voltage axis. Two areas of a waveform can
be zoomed at the same time. This function is useful when you want to observe one part of a waveform in detail that
was acquired over a long period of time. You can specify the area to be zoomed or the zoom position (position of the
zoom box).
Zoom Box Z1
Main (normal)
waveform
display area.
Zoomed waveform
display for Z1
Zoomed waveform

Zoom Box Z2
You can display two zoomed
waveforms, Z1 and Z2.
X-Y Waveform Display
User’s manual section 10.6, “Viewing the Phase between Measured Waveform on the XY Display”
This function takes the signal level of the specied waveform assigned to the X-axis (horizontal axis), and the signal
level of another waveform assigned to the Y-axis (waveform for which display is ON), and displays the relationship
between the two. You can observe an X-Y waveform and the normal T-Y waveform (waveform based on the time
axis and signal level) simultaneously. Up to two X-Y waveforms can be displayed on the screen.

IM 701310-02E

Introduction to Main Functions
Waveform Computation
User’s manual chapter 9, “Computation”
The following operations are available: arithmetic (+, -, x), linear scaling, integration, phase shift, moving
average(smoosing), IIR filter, edge count, and rotary count. A maximum of eight computed waveform can be
displayed.
Reference Waveform
User’s manual chapter 14, “Displaying Reference Waveforms”
Any of input waveforms, other computed waveforms, and previously stored input or computed waveforms can be se-
lected for display.
You can also specify the reference waveform for waveform computation.
Displaying Accumulation
User’s manual section 7.7, “Displaying Accumulation”
The display time of old waveforms can be set longer than the waveform update period, so that newer waveforms are
superimposed (accumulated) on older waveforms. There are two modes, as follows:
Count
The specied number of waveforms are superimposed. A gradation is applied according to the data frequency.
Time
Waveforms for the specied time are superimposed. A gradation is applied from older data to new.
Cursor Measurements
User’s manual section 10.1, “Making Cursor Measurements”
You can place cursors on a waveform to display the measured values at the points where the cursor intersects with
the waveform. There are six types of cursor available: horizontal, vertical, H & V, VT, marker, and serial cursor.

IM 701310-02E 15
Introduction to Main Functions
Automatic Measurement of Waveform Parameters
User’s manual section 10.2, “Automated Measurement of Waveform Parameters”
This feature automatically measures parameters such as the maximum waveform level and frequency. It can measure 30
waveform parameters (including delay between channels) related to the voltage (vertical) axis, time (horizontal) axis, and
waveform area.
• Up to 16 arbitrary parameters can be displayed.
• A total of up to 100000 data values can be stored for all waveforms.
• The measured values of waveform parameters can be used in computations.
Statistical Processing
User’s manual section 10.3, “Performing Statistical Processing of the Measured Values of Waveform Parameters”
User’s manual section 10.8, “Displaying a Histogram, Trend, or List of Automatically Measured Waveform Parameters”
The following ve results of statistical processing are performed on the same two measured items from automatic
measurement of waveform parameters.
Statistical items and values
Measurement

Results of statistical processing
Max: maximum value
Min: minimum value
Avg: average
Sdv: standard deviation
Cnt : count, or the number of
measured values on
which statistics are taken
The following three types of statistical processing are available.
Measurement per cycle/statistical processing within the measurement range
Waveforms are delimited every cycle from the left side of the screen to the right (oldest to
youngest), then each cycle is measured for the selected measurement item and statistics are
calculated.
Normal measurement/statistical processing
During measurement, all waveform data acquired up to the current time are measured for the
selected measurement item and statistics are calculated.
Measurement and statistical processing of history waveforms
History waveforms are measured for the selected measurement item, and statistics are
calculated. Measurement and statistics are taken starting with the oldest waveforms.
You can also display the measured results in a list, trend, or histogram.

Introduction to Main Functions
Snapshot
User’s manual section 8.7, “Taking and Clearing Snapshots ”
Using the Snapshot function, you can temporarily freeze a waveform on the screen that would ordinarily be lost when
the screen is updated. Snapshot waveforms are displayed in white, allowing you to easily compare them with the
updated waveforms. Furthermore, you can save snapshot waveforms to a memory medium, or print them out as
screen images.
To delete a snapshot waveform, press the SNAP CLEAR key.

Telecom Test
User’s manual section 10.4, “Telecom Testing ”
There are two types: a mask test used for analyzing communication signals, and an eye pattern automatic measure-
ment of waveform parameters test (the eye pattern automatic measurement of waveform parameters function applies
to rmware version 1.60 or later).
When you turn ON telecom test, the accumulate display (Count mode) automatically appears.
With the mask test, mask patterns created using the free software available on the Yokogawa Web site are loaded
onto the DL9000, and the waveforms that pass through the mask portion are counted.

Connecting the Probe
User’s manual section 3.4, “Connecting the Probe”
User’s manual section 3.5, “Compensating the Probe (Phase Correction)”
Connect a probe to the DL9000’s measurement input terminal (CH1).
Connect the tip of the probe to the probe compensation signal output terminal on the front panel of the DL9000.
Connect the probe’s ground wire to the functional grounding terminal.

Before connecting the probe, you must read the warnings in the user’s manual listed in
section 3.5, “Compensating the Probe (Phase Correction).”
• When actually making waveform observations using the probe, you must follow the procedures in the user’s manual for probe
phase correction (section 3.5), and calibration (section 4.8). Failure to use the probe correctly will result in incorrect waveforms.

Displaying a Waveform on the Screen
This section explains how to perform convenient, basic setting initialization and autosetup when you want to display
common repeating waveforms such as sine waves and square waves.
Initializing Settings
User’s manual section 4.4, “Initializing Settings”
The procedure below restores the settings that are controlled using the front panel keys to their factory default values.
If this is your rst time to use the instrument the procedure is not necessary, but performing the procedure now will
help you remember it for future reference. This initialization procedure is also useful when reentering settings to
match the input signal.
SETUP 2The initialization executes.
1Press the SETUP key.
To restore the settings prior to initialization, press this
button.
• After initialization, display for all channels is turned
ON, and the instrument enters START status.
• Items that cannot be initialized with the Initialize
soft key are as follows:
Date/time setting, communication related settings,
settings and waveform data stored in internal
memory, and language settings.
To initialize all settings but the date/time setting
and settings and waveform data stored in internal
memory, perform the procedure below. Note that
settings cannot be restored after this procedure.
Turn the power switch to the DL9000 ON while
pressing the RESET key.
Note
Auto Setup
User’s manual section 4.5, “Performing Auto Setup”
You can automatically enter vertical axis, horizontal axis, and trigger settings according to the input signal. This
function is useful when you just want to quickly display the signal in order to determine what kind of signal it is and
what sort of settings might be required to measure it.
SETUP 1Press the SETUP key.
To restore the settings prior to auto setup,
press this soft key.
2Auto setup executes.
Input signal on CH1
• When you execute auto setup, only the display of
the channel on which the signal is being input is
ON.
• The waveforms on which auto setup can be
performed must have the following properties:
Frequency: approximately 50 Hz or higher
Absolute value of input voltage: max. value of 20
mV (1:1) or more
Type: repeating wave (non-complex)
