The "Mobile" SignalExplorer: from the Lab to the Field
With a three-mode power supply (AC, 12 VDC and battery) the DL1600 goes
everywhere you need to make measurements.
Serial bus (I2C, SPI, CAN) signal capturing and protocol analysis
The DL1640 and DL1640L offer enhanced basic performance
characteristics (200 MS/s and 200 MHz bandwidth, and four input
channels) in a surprisingly compact and lightweight package
(approximately 3.9 kg). The ability to capture records up to 32MW long,
simultaneously on four channels, allows you to capture both highfrequency signals and lower-frequency singals over long periods of
The display consists of a wide-angle 6.4-inch color TFT LCD allowing
clear viewing of waveforms in a variety of measuring environments.

䊉DL1600 Series Lineup
Analog input channels
I2C bus signals (SCL and SDA), used extensively in
home electronics such as analog and digital
televisions, and video cameras, and in
communications equipment such as mobile phones
can be captured with specialized triggers and
displayed as waveforms.
Triggers can be based on start conditions, nonack(when acknowledgement is not received) and user
specified address and data patterns.
Use up to 32 megawords of memory (DL1640L) to
acquire long strings of I2C bus waveform data and
then analyze the data in a time-series manner.
SPI Bus (a synchronous 8-bit serial bus) waveforms
can also be analyzed and the data displayed.

The DL1640/1640L can be
powered in three ways (AC, 12V
DC and battery), giving you the
flexibility to make measurements
just about anywhere. Power the
unit directly from an in-vechicle
battery using 12 VDC, or attach the
battery and power the unit in the
field (runs approximately two hours
on a full charge*), or use the AC
input at your test bench in the lab.
This DL adapts to the situation!
* Operating time depends on usage
Using dedicated triggers, CAN bus signals can be captured and
displayed as waveforms. (The CAN bus option supports both
high-speed and low-speed CAN. CAN is used widely in the
internal communication busses of automobiles, FA machinery,
medical equipment, and other devices.) Analysis performed
according to the CAN protocol can be displayed in a list together
with the waveforms.
Use up to 32 megawords of memory (DL1640L) to acquire long
strings of CAN bus waveform data and then analyze the data in a
time-series manner.
Analysis results are then listed along with the waveform. Results
include: ID and Data fields, ACK field status and other
The CAN bus search function quickly searches the acquired data
for user-defined ID and data patterns, RTR or ACK bits. Searchs
for indefinite bit states can also be performed.
The DC-power option is available on the DL1640 and DL1640L.
The main unit must be connected to ground.
Simple and enhanced triggers
A → B(N)
A Delay B
Action-on trigger
Triggers on a rising or falling edge.
Triggers if condition B goes true after
condition A has gone true and an interval at
least equal to the delay setting has elapsed.
Triggers when the state conditions
(H or L) on multiple channels goes true
and a channel edge condition is met. A
clock setting can also be made.
Triggers based on the pulse width.
The trigger may be selected from the
following options: Pulse < T, Pulse > T,
T1 < PLS < T2, T1 > PLS > T2, Time-out.
The width trigger may be combined with a
window trigger, in which two trigger level
values can be set. This makes it possible
to set a virtual pulse as a trigger condition.
Triggers when any trigger condition on
multiple channels goes true. The OR
trigger may also be combined with a
window trigger.

With the action-on trigger, a specified action is automatically executed each time the
trigger is activated. You can use the trigger for a variety of actions, such as automatically
saving captured data. The action-on trigger is useful for purposes such as collecting data
in continuous tests.

Small Footprint
The DL1600 takes up less bench space than an A4 piece
of paper, making it ideal for testing in areas with limited
space. The DL1600 is also lightweight; weighing only 3.9
kg (without options). From the lab to the field, the DL1600
works wherever you do; and takes up “very little space.”
Quick and simple saving of
USB flash memory (USB rev 1.1 compliant) can be used for
saving a variety of data files, including waveform data*.
When you select the PC card interface as the removable media
type, you can use ATA flash
memory cards, compact
flash, high capacity
microdrives, and other media.
Additionally, 2 MB of flash
memory is built into the main
unit. The flash memory is
convenient if other storage
media is not handy.

Accurately, Easily, and Instantly Explore the Signals You Are Looking For
Real-Time Digital Filtering for Finding Signals Hidden in Noise
Up to 32 MW of data (with the DL1640L) can
be acquired even when all four channels are
used. This long memory allows you to
maintain fast sampling speeds even while
capturing long-duration events.
One important role for oscilloscopes is measuring the
noise on a waveform. Sometimes, however, this noise
prevents you from observing the targeted signals.
Real-time digital filtering lets you easily apply a low
pass filter while capturing data, so that waveforms
hidden in noise can be clearly displayed.
In the picture at the right, three signals from a
switching power supply have been captured
(switching element voltage, current, and
primary-side surge current) from the time the
power is turned on, until the swithing starts
and stabilization is reached. The DL1600's
super long memory lets you maintain high
sampling rates for capturing individual
pulses, and still record for a long period of
Filters can be set separately on each channel. In
combination with an analog filter, cutoff frequencies
ranging from 20 MHz to 10 kHz can be set. In addition,
when the real-time digital filtering is used in highresolution mode, data resolution increases to as much
as 13 bits, and signals can be reproduced even more
accurately on the screen.

All-Points Display and Fast Screen Updates Capture Hidden Abnormalities
All-points display shows every single data
point that is captured in memory. All-points
display shows phenomena that may be
missed in a compressed waveform display.
With Yokogawa's proprietary Data Stream
Engine II, screen update rates don't slow
down, even when zooming the waveform, or
performing automatic waveform
measurments.With fast screen update rates,
changes made to instrument settings
happen instantaneously and instrument
control is responsive.

Smart Search Functions Help Find
the Data You Need
"I want to find a specific serial data pattern", "I need to search for
surge pulses of less than 30 ns", "I want to only extract
waveforms that occasionally overshoot by an excessive
amount".......As data volume increases, it becomes more
important to be able to search for target phenomena efficiently.
The Smart Search function automatically detects serial patterns,
pulse widths, rising edges, falling edges, and other phenomena
in the captured waveform data. These phenomena are then
displayed in the zoom screen. Smart Search will significantly
improve the efficiency of your development and evaluation work.
Using the Ethernet interface(optional), you can easily connect to
a network or a PC.
Using the Internet Explorer web browser on your PC, you can
view the DL1600's screen, save scope data to the PC, or load
setup files from the PC to the scope.
Easily copy and paste files to and
from a PC from the internal flash
memory drive and other internal
storage media. You don't have to
use a separate program to transfer
the data.

History Memory & History Search
Easily and reliably capturing
abnormal waveforms that occur
infrequently is an important
aspect of troubleshooting. It is
impossible to predict the
moment and timing at which an
abnormal waveform might
appear. The history memory is
effective in these cases. After
stopping the acquisition, the
DL1600 series can use its
History Memory to view, search
and analyze up to 16,000
previously acquired waveforms.

History Search
You can extract acquisitions that meet
specific criteria from this large volume of
historical data. Search methods include
judging whether a signal passes through or
does not pass through a specified "box"
(screen area), and judging computed results
of waveform parameters such as minimum
and maximum values.
