The DL950 is designed to offer manufacturers a highly detailed view of an application’s electrical and mechanical behaviour.
In transportation, uses include testing electric vehicles and SiC/GaN inverters; in power, it can capture data on renewable energy systems, while manufacturers of industrial equipment will find the DL950 invaluable in testing high-efficiency motors, robots and sensors.
The device is said to provide a unique combination of the high-speed sampling and signal fidelity of an oscilloscope and the long-term data recording capabilities of a recorder.
Compared to older sibling the DL850E, the new DL950 ScopeCorder 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 analog channels with 10 MS/s at 16-bit or up to 128 digital channels.
The DL950 ScopeCorder is said to provide developers with a high degree of insight into the behaviour of these systems by capturing and analysing a wide variety of electrical signals, mechanical performance parameters indicated by sensors and decoded vehicle serial bus signals.
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, allowing users to choose the best method for their application. They 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 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. A fibre-optic cord and the Yokogawa’s IS8000 PC software are used for transmission.
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 in-vehicle endurance testing and capturing rare spontaneous events.
The DL950 provides ultimate versatility, as it can be connected to 21 types of input modules. These include 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 synchronized 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 subunits can be synchronized to start and stop their measurements via signals from the main unit.
The DL950 is used via a 12.1-inch touch screen. Yokogawa’s power analysers and a selection of other instruments can be time synchronized 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.
