Yokogawa Releases DL750 ScopeCorder - A Truly Portable Waveform Measuring Instrument with 1-GWord of Memory

Yokogawa Electric Corporation announced today that it has developed the DL750 ScopeCorder and will release it to Japanese market on May 13, 2002, and to others on May 27. The new DL750 product is the latest in the DL700 series of waveform measuring instruments that can be used for observing a wide variety of waveforms from physical to electric signals. The DL750 ScopeCorder has incorporated 1 gigaword of memory, the largest for this class of device, and is half the size of previous generation products. It is also equipped with the GIGAZoom function, which uses a specially developed ASIC to instantaneously display data stored in the large memory.
Yokogawa launched the DL700 series in 1997, based on the concept of providing waveform measuring instruments that can not only be used for electric signal observation, for which conventional digital oscilloscopes were targeted, but can also be used for physical signals such as mechanical signal outputs and temperature changes. Its multi-channel input and large memory features were well received in the automobile and other electro-mechanical markets, and so far approximately 7000 products have been delivered. The automobile industry, in particular, is required to make many complex measurements and evaluations, at the development stage, as part of its role in addressing environmental issues. This has intensified the need for measuring instruments used for product development and evaluation, with multi-channel input and large memory capabilities. To further improve development efficiency, smaller models that are easier to move between workplaces, such as benches, have long been overdue. The DL750 ScopeCorder can act as an oscilloscope for capturing instant events, as well as a data recorder for prolonged trend measurement.

Features

- GIGAZoom function for high-speed processing of 1 gigaword of data
The DL750 ScopeCorder has successfully implemented the GIGAZoom function, which processes a large amount of data at high speed and displays waveforms immediately. No other products in this class can display 1 gigaword of data that quickly.

-

DualCapture function for measuring both low- and high-speed events
This function can capture conflicting slow trend data and fast data including surge and noise simultaneously. These types of data were previously collected by multiple measuring instruments. By allowing users to collect these types of data with one unit, the DL750 contributes to reducing data collection time, and reduces purchasing costs.

-
Achieves triple analog accuracy at half the size
A special module developed by fully employing the latest semiconductor technologies has made it possible to reduce the size of the DL750 to half that of previous generation Yokogawa products with 16 input channels. Furthermore, its has triple the frequency bandwidth (3 MHz) and measurement accuracy of DC analog voltages (±0.5%) compared to the former DL716.

-
Allows remote monitoring and operation with Web server function
The DL750 can be monitored, operated, and managed remotely through its Web server function, which uses an Ethernet interface. This allows, for example, developers to monitor data of a DL750 located on a workbench from an office area, contributing to greater work efficiency.

Yokogawa's Approach To The Waveform Measuring Instruments Field

Yokogawa Electric Corporation moved into the remarkably promising market of digital oscilloscopes in October 1988 with its introduction of the DL2100, a series of high-speed digital oscilloscopes. In order to enrich the lineup, Yokogawa has since been successively developing additional models ranging from midrange general-purpose to high-end models. In the mid-range general-purpose market, Yokogawa has established a solid reputation as a leading manufacturer.
As opposed to conventional digital oscilloscopes which were tailored for the observation of PCB circuits and others in the electric and electronic markets, the DL700 series is targeted at a wide range of observations from electric signals to physical signals such as sensor outputs, mechanical signal outputs, and temperature changes. The DL700 series is Yokogawafs strategic product that aims to become the standard in the field of measurement of physical quantities at 10 MS/s or lower. Yokogawa believes that by supporting wider applications and having multi-channel and large-memory capabilities, the new DL750 will further enhance its lineup of waveform measuring instruments.
