ADVANCING AND ACCELERATING
Yokogawa Test & Measurement has introduced the DL950 ScopeCorder and the IS8000 integrated measurement software platform

okogawa Test & Measurement has added a new instrument to its ScopeCorder family of portable multi-
channel data-acquisition recorders, extending and improving their speed, channel count and data acquisition features. With Industry 4.0 rolling out across factories,
developers of mechatronics and automation are looking for test solutions that allow them to bring advanced products to market quickly. The Yokogawa DL950 is designed to offer manufacturers a detailed view of an application’s electrical and mechanical behaviour by easily consolidating waveforms from several test devices. Manufacturers of industrial equipment will
find the DL950 invaluable in testing high efficiency motors, robots and sensors. Providing a combination of the high-speed
sampling and signal fidelity of an oscilloscope and the long-term data recording capabilities of a recorder, the DL950 measures signals at a high bit resolution while securing data in the harshest of environments. Building on the capabilities of the DL850E, the DL950 can handle larger amounts of data at a faster sample rate and with a longer recording time. It has a large acquisition memory up to 8 Gpoint, and a 200 MS/s sample rate at 14-bit, compared to the DL850E’s 100 MS/s at 12-bit. This is twice the sample rate but with much more detail. The DL950 can run up to 32 isolated analogue channels with 10 MS/s at 16- bit or up to 128 digital channels. The dual capture feature offers both data
acquisition recorder functionality and the sample speed and trigger features of an oscilloscope. This allows developers to analyse the finest waveform details while observing multi-channel measurements over longer periods. The DL950 offers five options for acquiring data, users can opt for normal acquisition into the fast internal acquisition memory, recording to flash memory (coming soon), recording to the internal hard disk (SSD) or directly to the PC via normal Ethernet or opt for 10 Gigabit Ethernet. Data can be captured to a PC streaming

The DL950 ScopeCorder provides developers with a high degree of insight into the behaviour of mechatronics systems by capturing and analysing a wide variety of electrical signals and mechanical performance parameters indicated by sensors and decoded serial bus signals
over a very long time at up to 160 MB/s, with data volumes limited only by the PC’s storage size. Using 10 Gigabit Ethernet, data can be transferred from the DL950 to a PC at 50 times the speed of its predecessor. The DL950 will also feature Flash Acquisition
(coming soon), used to store data when a PC cannot be used, for example when capturing data from a robot or industrial motor on a remote test site. In these applications the unit would usually need to be switched off before moving it to an office to save data on a PC. Using Flash Acquisition, data can be captured over a long time with a high-speed sample rate of 20 MS/s (8CH) and 10 MS/s (16CH). The 512GB internal SSD can record up to 50
days. Depending on the sample rate it can record for five hours on one channel at up to 2 MS/s, or record at 200 kS/s for 20 hours with 16 channels. Waveforms from dual capture can also be recorded, useful for endurance testing and capturing rare spontaneous events. The DL950 can be connected to 21 types of
input modules, including 12-, 14- and 16-bit isolation modules, universal voltage/ temperature modules, acceleration/voltage modules, strain modules and frequency modules. Up to five DL950s can also be synchronised
to allow the use of up to 160 voltage channels. Alternatively, up to 640 temperature channels can be used, employing 16 channels with eight slots for each of five DL950 units. The sub-units can be synchronised to start and stop their measurements via signals from the main unit. The DL950 is also easy to use via a large 12.1
inch touch screen, providing convenient access to its wealth of features. Yokogawa’s
power analysers and a selection of other instruments can be time synchronised through the device’s integrated IEEE1588 PTP master function and the IS8000 Integrated Software Platform. The units can also be controlled remotely, allowing home workers to continue conducting tests while working away from the test laboratory. Dedicated application menus simplify the
setup. Touching an application icon brings up the graphical setup screen for the application, while users can also register frequently used applications as favourites. Yokogawa Test & Measurement has also
introduced an integrated software platform that synchronises the data from several test instruments on the same screen, giving developers a clearer picture of the timing of control signals and switching events and how products being tested react to them. The IS8000 Integrated Measurement
software platform solves the challenge of developing sophisticated products such as motor inverters, which often need several instruments to capture all the test data. Oscilloscopes offer high sample speed and
in-depth views of waveforms, Yokogawa’s ScopeCorder can display many types of signals in high resolution, while power analysers offer accuracy in power measurements. However, operating these multiple instruments can be difficult due to the different user interfaces and the need to correlate the timing of the various input signals. The IS8000 software platform meets this
challenge by tightly integrating the timing, control, and data collection from several
