Scopes claim world's longest memory

The DL1640 SignalExplorer family of digital oscilloscopes from Yokogawa features the world's longest memory (32Mword) along with four-channel simultaneous operation and real-time digital filtering.

The DL1640 SignalExplorer family of digital oscilloscopes from Yokogawa features the world's longest memory (32Mword) along with four-channel simultaneous operation and real-time digital filtering.

The new oscilloscopes offer full functionality within a small, lightweight package, and are ideally suited to waveform measurements involving low- and high-speed sampling over long time periods in consumer electronics, automotive and mechatronics applications.

The long memory (32Mword in the DL1640L and 8Mword in the DL1640) enables long-duration, multichannel observations to be made without sacrificing high-speed sampling, while the real-time digital filter extracts signals buried in high-speed noise.

The new oscilloscopes retain the high-speed all-points display and smart search functions of other instruments in the SignalExplorer series, but with a 20% reduction in volume, weight and surface area, and one-third the power consumption of earlier models.

The instruments feature four-channel operation with 200Msample/s sampling and a 200MHz analogue bandwidth.

The compact size (220 x 266 x 268mm) means that the units occupy less than an A4 size 'footprint' on a test bench or desktop, while the light weight of only 3.9kg makes the oscilloscopes easily portable.

The DL1640 Series uses a 6.4in wide-angle TFT colour liquid-crystal display screen, and offers a choice of a PC card drive, Zip drive or floppy drive for internal storage.

A wide range of interfaces includes optional USB and Ethernet connectivity.

A web search function allows easy file transfer, waveform monitoring, and parameter trend graph plotting on standard browser software such as Microsoft Internet Explorer, while the PC card interface supports large-capacity microdrive and hard disk cards.

The price of the DL1640 is GBP 4495 with the DL1640L costing GBP 5500 (prices excluding VAT).
