Reliable capture, from fast-short pulses to long recordings

Save time using unattended supervisory data acquisition

Best-in-class Deep Memory & Architecture

Features, Functionality, and Operability – satisfying the needs of today's engineers.

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 defines the architecture and
power of the DLM4000
In order to find and display the desired parts of the signal within the long memory,
powerful waveform search and a unique dual-window zoom function are provided.

With the DLM4000 series, up to 20,000 previously captured waveforms
can be saved in the automatically segmented acquisition memory without
sacrificing 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 find and analyze rarely-occurring abnormal signals which may not
cause a trigger to occur.

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

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 notification to a designated e-mail address.
Waveforms in which an abnormality occurred can be saved for confirmation and analysis at a
later time.
Let the DLM4000 save you time.

Selecting a long Time/Div setting automatically sets the DLM4000 into ‘Roll Mode’, which
performs just like a recorder. During roll mode, powerful real-time waveform processing such
as filtering, 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.

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

During Roll Mode, real-time waveform processing

such as PWM-filtering or pulse-counting means

un-interrupted recording

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

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

History search 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.

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

with ease

With built-in GO/NO-GO testing, unattended data acquisition becomes

a powerful tool.

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 combina-
tion of two bus signals is possible, or an A and B combination of
different trigger types.
This comprehensive trigger suite means you capture the correct
waveforms - even for fast and complicated sets of waveforms
containing combinations of analog, digital, and serial bus signals.
