The DL1640S from Yokogawa is the latest addition to the company's DL1640 family of digital oscilloscopes, which also includes the instrument with the world's longest memory of 32Kword per channel.

The new DL1640S incorporates most of the measurement and display features of the top-end DL1640L model, and with a price of less than GBP 3500 it offers exceptional value for money for an instrument with 100Kword of memory per channel, 200Msample/s sampling and 200MHz bandwidth.

Other features of the four-channel DL1640S include real-time digital filtering, dual-zoom capability for examining captured waveforms in detail, high-speed screen refresh, and smart search functions.

The DL1640S uses a 6.4in wide-angle TFT colour liquid-crystal display screen, and is housed in a compact package measuring only 220 x 266 x 268mm.

As a result, the unit occupies less than an A4 size 'footprint' on a test bench or desktop.

The light weight of only 3.9kg makes the oscilloscopes easily portable.

Captured data can be stored externally using a PC card drive or Zip drive; a floppy disk drive is also provided 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.
