INDUSTRY NEWS 21 start time of the observation on that instrument with the start time on the power meter (the position of the data update cycle) to time- synchronize the waveform sample rate with the power values or calculated values of the power meter. It is practical to synchronize the times in units of one second, but it is quite difficult to manually perform time synchronization within 100 ms. Now, since more tests require the simultaneous acquisition of waveform data and power data, ensuring the simultaneity of data has become a major issue. With the 10G Ethernet interface option (/C60), the DL950 provides 10 Gbps high-speed data transfer. While the conventional model DL850E provides PC streaming at 100 kS/s (16ch), the DL950 offers 50 times faster data transfer at 10 MS/s (8ch), allowing measured data to be displayed on the PC software in real time. In inverter measurement, the high switching frequency requires high-speed data capture. The DL950 transfers data continuously to a PC at up to 10 MS/s, so that the data can be output without interrupting the test. There is no need to wait a matter of minutes just for data transfer to complete. Furthermore, by combining the ScopeCorder DL950 with the WT5000 power analyzer, it is possible to achieve an industry first by performing high-precision power measurement with power traceability in synchronization with high-speed waveform data. The IS8000 integrated measurement platform can manage individual files as one project file. This eliminates the need to save a waveform data file and a power data file with the same name to associate them with each other or the need to manage files by creating a folder for each measurement data and storing a waveform file and a power data file in that folder. A data file can be divided into segments by specifying the length of time. The data for an entire measurement period and the data for the period desired for analysis during the measurement can be saved as separate files. For example, when measuring for 24 hours, the user can divide the file into one-hour segments and analyze the data of the segments where the measuring process is finished while continuing the measurement. After the measurement is completed, the file of the entire measurement period and the divided files can be managed as a project file. Measurement using two DL950s or measurement using the DL950 and WT5000 can also be managed as one project file. The fact that the user does not have to associate file names even in the measurement with the DL950 and WT5000 supports the improvement of development efficiency. The automatic report creation option (/RP1) allows report creation and output on a PC. A report can easily be created by setting the report layout (with image display) using the report creation wizard function (Figure 5). From the files measured or saved by the ScopeCorder or the Precision Power Analyzer, the user can choose measurement conditions, waveform output, measurement results, or other data. The report can be output to PDF or EXCEL. https://tmi.yokogawa.com Figure 5: Integrating a project file and divided files Contact DTI today to discuss your high voltage design. +1.972.248.7691 II www.deantechnology.com Outputs up to 6kV @ 30W Available as biasing or capacitor charging modules Cost effective, analog controls and monitors, and the best performance... ...for what you need now UMR Collection & PMT Series The higher standard of high voltage DC/DC power supplies.
