When 4 channels are not enough …

Bulletin DLM4000-00EN

For today’s challenging power electronics, automotive electronics and mechatronics:

Only one scope will do – the world's only eight-channel oscilloscope - the DLM4000.

The portable eight-channel DLM4000 is

the daily instrument of choice.

12.1” LCD enables eight waveforms to be easily observed. Portable

This combination with the optional
PBDH0150 High-Voltage Differential Probe,
creates a compact and

Typical Demanding Applications for the Eight-Channel DLM4000

Motor Control & Inverter Circuit Development

8ch

Key to efcient and reliable high-performance
electric motors is the modern inverter design, or
‘Intelligent Power Module’. Multi-channel,
high-speed waveform measurement is an absolute
necessity. Four channels are simply not enough.
Boasting eight true analog inputs, the DLM4000
empowers today’s engineer with a convenient and
comprehensive measurement system.

Example: 3 voltage & 3 current measurements of a 3-phase motor
Measurement of the gate-drive signals of six IGBTs within the inverter

4ch

Whole-system measurement is impossible
with a four-channel scope; the real difculty
is measuring the timing between IGBT gate
signals within the inverter. Voltage and
current measurements between 3 phases
and the IO of the motor driver IC is a very
challenging test with a four-channel scope.
The truly practical solution is an
eight-channel MSO.

Power Supply & Power Converter Test

During the evaluation of a power supply design, it is
necessary to measure noise, ripple, voltage margin and
current , as well as timing margins and the jitter of the
startup-shutdown sequences. As the number of waveforms
in modern power supply designs is increasing, especially for
intelligent digitally-controlled power supplies, battery
management systems, and wireless power supply systems ­a four-channel oscilloscope is not enough.

Recorder

A modern multi-channel recorder provides
enough channels and long record times;
however, due to modest sample and update
rates, the recorder is unlikely to be
successful at measuring high-speed
waveforms in the vicinity of CPUs & FPGA
such as communication signals,
high-frequency noise, and fast waveform
anomalies.

Electronic Control Unit & Mechatronic Test

Numerous I/O analog, digital, and serial-bus waveforms
surrounding the Electronic Control Unit (ECU) must be
measured. The DLM4000 offers ample channel-count
and architecture to monitor eight analog channels and up
to 24-bits of logic input while simultaneously performing
protocol analysis such as UART, I2C, SPI, CAN, LIN and

FlexRay. The DLM4000 can speed up the the R&D
process. Four channels are not enough.

4ch

The additional logic inputs of a four-channel
MSO mixed-signal oscilloscope provides
enough channels, but this method has a
blind-spot. Digital waveform analysis using
logic inputs alone cannot reveal anomalies
such as voltage drift, noise, distortion or
ringing, and measure rise-fall times. ECU
testing requires stringent examination of all
digital waveforms – and analog input
channels are the best tool for the job.

Limitation of 4ch MSO

Troubleshooting, total system test

For laboratory and eld troubleshooting, the ability to
measureas many suspicious signals as possible enables
quick solutions to be found.
The measurement time for system testing is often very
limited.
The 8 channels of the DLM4000 provide the capability to
measure more signals at one time, both now and to meet
future needs.

Example: Troubleshooting of infrequent problems
Comprehensive stability test of the whole system

Limitation of two

4ch

When four channels are not enough, it is
common to connect two separate four
channel scopes. This approach is not only
cumbersome but inter-waveform timing can
lack credibility and post-processing of the
waveform data les is twice as much work.
The sensible approach is an eight-channel
MSO.

Use the DLM4000 like an eight-channel memory recorder or select faster sampling rates up to

1.25 GS/s across all channels!

For fast-short waveforms
the comprehensive trigger suite
captures the waveforms you need!

In addition to basic trigger functions such as Edge, State, and Pulse
Width – Advanced trigger types are provided, including Edge OR
between multiple channels, Serial Bus trigger in which A combina­tion of two bus signals is possible, or an A and B combination of
different trigger types.

Best-in-class Deep Memory & Architecture

No-compromise ScopeCORE Architecture - the DLM4000 manages super-long record lengths
with ease

Extra Deep Memory (125 Mega-Points) Enables Long-Duration Measurement

For-four channel measurements in Single shot mode, you can add the /M2 memory
expansion option which provides a large memory of up to 125 Mpoints. Even at a fast
sampling rate of 1.25 GS/s, records as long as 100 milli-seconds can be captured.
Yokogawa’s proprietary ScopeCORE IC assures responsiveness even for long record
lengths. ScopeCORE maintains a responsive waveform display even when parametric
measurements and waveform calculations are used and denes the architecture and
power of the DLM4000
In order to nd and display the desired parts of the signal within the long memory,
powerful waveform search and a unique dual-window zoom function are provided.

You can replay waveforms later, so you'll never miss an abnormal waveform

- History Function –

With the DLM4000 series, up to 20,000 previously captured waveforms
can be saved in the automatically segmented acquisition memory without
sacricing acquisition rate. This History function, enables you to display
just one or all of the previously captured waveforms (history waveforms)
on screen. You can also perform cursor measurement, computation, and
other operations on history waveforms. Using the History function, you
can nd and analyze rarely-occurring abnormal signals which may not
cause a trigger to occur.

History search function

You can search the 20,000 previously captured waveforms
for history waveforms that meet specied search criteria.
You can also perform cursor measurement and other types of
analysis on the search results.

Replay function

Waveforms can be displayed one at a time, using the rotary
knob. With the Replay function, history waveforms can be
automatically played back, paused, fast-forwarded, and
rewound.

Dual-window zooming enables

two separate areas to be displayed.

Save time using unattended supervisory data acquisition

For long term recording, 'roll mode' gives you
both realtime measurements and the waveform detail!

Selecting a long Time/Div setting automatically sets the DLM4000 into ‘Roll Mode’, which

During Roll Mode, real-time waveform processing

such as PWM-ltering or pulse-counting means

With built-in GO/NO-GO testing, unattended data acquisition becomes
a powerful tool.

performs just like a recorder. During roll mode, powerful real-time waveform processing such
as ltering, pulse counting and rotary counting can be executed simultaneously.
This means that the DLM4000 can observe a PWM and encoder waveform – analysis of these
waveforms in realtime is normally challenging – but the DLM4000 does it.
Furthermore, checking the waveform by using the powerful zoom feature and parametric
measurements is also possible during roll mode acquisition. This enables ongoing realtime
waveforms to be analysed without interrupting or pausing the acquisition. Many oscilloscopes
simply cannot do this.

04

A GO/NO-GO test result can be determined using customizable trigger conditions including
waveform zoning, parameter measurement, and other criteria. For either a GO or a NO-GO test
result, an action can be executed such as sounding a buzzer, saving the current waveform, or
sending a notication to a designated e-mail address.
Waveforms in which an abnormality occurred can be saved for conrmation and analysis at a
later time.
