Fourth generation ScopeCorder boosts capture rates and synchronisation
The 12in touchscreen on the DL950 ScopeCorder supports 14bit captures at 200Msample/s with remote operation for up to 50 days

Data from the ScopeCorder 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 feature Flash Acquisition used to store data when a PC cannot be used, for example when capturing data from within a vehicle, power plant or other similar applications. 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 in-vehicle endurance testing and capturing rare spontaneous events.

Up to five DL950s can be synchronized via a proprietary optical cable or IEEE1588 link 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 IS8000 Integrated Software Platform allows multiple Yokogawa units such as power analysers or MSO oscilloscopes to be connected and synchronised with a ScopeCorder, again using 1588 links. This allows systems acorss the R&D and produciton development cycle to be used together with the synchronised data form all systems displayed on a single screen. All the test units can be controlled remotely, allowing home workers to continue conducting tests while working away from the test laboratory.
