Scopes put analogue and logic side by side

Yokogawa is now offering a 16bit high-speed logic input capability, previously available only as an optional extra, on its DL7400 Series of high-performance digital oscilloscopes.

Yokogawa is now offering a 16bit high-speed logic input capability, previously available only as an optional extra, on its DL7400 Series of high-performance digital oscilloscopes.

The new "free logic" feature, with a maximum toggle frequency of 250MHz, allows the DL7400 to measure and display eight 500MHz analogue channels and the 16bit logic input simultaneously.

When combined with the instrument's long memory - 8Mword per channel on all channels or 16Mword with 2Gsample/s sampling rate when interleave is turned on - the ability to capture and display analogue and logic inputs side by side makes the DL7400 an ideal multichannel analysis tool.

Applications include areas such as automotive monitoring and power analysis as well as signal integrity measurements where it is necessary to observe the analogue content of digital waveforms.

The DL7400 Series incorporates a wide choice of data analysis and search functions, including history search, cycle statistics, pulse count and serial pattern search.

Powerful trigger capabilities and user-defined mathematics add to the instruments' versatility.

The instrument includes PC card and USB interfaces as standard, and SCSI and Ethernet interfaces as options.

PC-based software is available for remote control and data analysis, and the instrument can be configured as a web server for file transfer, e-mail, data capture and trend analysis.
