INTRODUCTION
If you need the best tool available for measuring physical and electrical phenomena under 100 mega-samples per second, look no further than the Yokogawa DL850 ScopeCorder. This unique and versatile instrument combines the benefits of a high speed oscilloscope and traditional data acquisition recorder into a single, portable instrument.
CHANNEL COUNT AND VERSATILE INPUTS
The DL850 ScopeCorder can accommodate up to 128 channels of assorted types. You can equip your ScopeCorder with isolated, simultaneously sampled modules up to 100 megasamples per second. If you don’t need the highest sample rates, choose the new 16-channel multiplexed module, or any of three universal voltage input modules which exchange speed with higher voltage resolution, accuracy, and input ranges. An RMS coupled mode lets you monitor and trigger off changes in RMS levels. With its modular architecture, a ScopeCorder will handle nearly every type of electrical or physical signal. You can arbitrarily combine fifteen unique module types, supporting direct input of popular sensors like thermocouples, accelerometers, strain gages, tachometers, and more.
PORTABLE AND MULTI-FUNCTION
The DL850 makes use of a large, 10.4 inch LCD display, an internal hard drive, and a thermal printer on top. Three USB ports, an Ethernet port, an e-SATA port, a video port, a GPIB port, and a SD-card slot populate the unit's left side panel. On the right side, the DL850 has room for eight input modules. Incredibly, the DL850 ScopeCorder packs all these features and achieves ten times the sample rate, display, and memory handling speeds as its predecessor. As a diagnostic tool, the ScopeCorder offers all the measurement, and analysis tools of a modern digital oscilloscope, like cursors, waveform parameter calculations, math and DSP channels, fast fourier transforms, and more. That means that in most cases, you can analyze your data immediately and get results with no offline post processing.
DEEP MEMORY
Yokogawa perfected deep memory, and the ScopeCorder has its share of it: up to two billion points of data can be recorded continuously at 100 megasamples per second, per channel. Regardless of memory size, the ScopeCorder’s GIGAZoom engine allows you to smoothly zoom in and out of a signal, even while acquisition is in progress.
Due to its unique architecture, the ScopeCorder automatically allocates its memory to best-accommodate your test strategy. Simply set your desired sample-rate, and Yokogawa’s exclusive “History” feature intelligently utilizes the remainder of the available memory – allowing you to view and save previously-captured acquisitions. Another unique function available in the ScopeCorder is it’s “Dual Capture” feature, which lets you configure both high speed and low speed rates. In this mode, the DL850 continuously logs data at the slow speed until a trigger condition is met. At the higher sample rate, the ScopeCorder acquires a transient waveform, with multiple waveforms for multiple triggers, all while continuously logging at the low speed rate.
BETTER THAN AN OSCILLOSCOPE FOR MECHATRONICS
Electro-mechanical systems demand a different set of measurement techniques than pure electrical systems– and the ScopeCorder delivers higher vertical resolution, channel count, isolation, filtering, and abundant acquisition memory compared to general purpose oscilloscopes. That means you’ll be able to detect small changes, even across large dynamic ranges, and monitor more signals simultaneously. It also means that you won’t need to cope with external signal conditioning components, and you can maintain high sample rates for longer observation periods. Since the DL850 Scopecorder uses familiar oscilloscope controls, triggers, and analysis functions, you can expect more performance without more complexity.
RECORDER FUNCTIONS
Yokogawa’s designers built the ScopeCorder as an oscilloscope that also has the powerful advantages of a recorder. One of the advantages of a recorder is un-attended operation. By enabling “Action on Trigger” or “Action on Stop”, you will find the ScopeCorder to be an invaluable companion. The DL850 ScopeCorder can automatically send you an email, print your captured data, sound an alarm, and save your data to a file when it detects a fault condition. Whether your observation times are microseconds or months, the ScopeCorder will stay on the job and your data will be waiting for you when you are ready for it.
