As companies develop more energy efficient technologies for electric vehicles it requires a highly detailed view of an application’s electrical and mechanical behavior.
Yokogawa has announced the release of a new measurement product that will offer new levels of insight into complex electrical and mechanical systems.
The DL950 is the latest in the Yokogawa ScopeCorder family and offers high-speed data acquisition facilities, extending and improving their speed, channel count and data acquisition features.
The DL950 is suited for applications such as testing electric vehicles and SiC/GaN inverters, as well as ECUs, sensors and in-vehicle communications networks.
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. 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. 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 captures and analyzes 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 analyze 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.
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 fiber optic cord and the Yokogawa’s IS8000 PC software are used for transmission.
The DL950 will also soon feature Flash Acquisition, used to store data when a PC cannot be used, for example when capturing data from within a vehicle. 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).
This is ideal for developers of transport solutions, as it allows capturing the high-speed switching events of components such as inverters, motors and ECUs that increasingly form part of electric vehicles.
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 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.
“Offering the versatility to discover more from a large number of input types, the insight available from a high bit resolution and a high level usability from easy set-up, the DL950 gives developers the tools they need to gain detailed information on the behavior of energy efficient and new renewable energy technologies and devices,” said Terry Marrinan, Yokogawa Test & Measurement’s vice president for Europe & South East Asia.
