Big memory handles big waveforms

The new DL750 ScopeCorder from Yokogawa is a truly portable waveform measuring instrument that combines recorder and oscilloscope technologies.

The new DL750 ScopeCorder from Yokogawa is a truly portable waveform measuring instrument that combines recorder and oscilloscope technologies.

The instrument's exceptional memory length of up to 1Gword coupled with 10Msample/s sampling makes it ideally suited to the capture and analysis of high-speed signals over long time periods of up to ten days.

The DL750 ScopeCorder can act as an oscilloscope for capturing instant events and as a data recorder for prolonged trend measurement.

A dual-capture function allows the instrument to capture slow trend data and high-speed events simultaneously, while a high-speed processing facility called GigaZoom can process the entire 1Gword of data stored in the memory and display it virtually instantaneously.

The instrument can capture data on up to 16 analogue channels plus one 16bit logic input.

Data are sampled at up to 10Msample/s with 12bit A/D resolution via a two-channel isolated input module, or at 1Msample/s at 16bit using a high-sensitivity (1mV/div) input module.

A wide range of trigger functions is available for capturing a variety of waveforms, while history memory and smart search facilities provide effective access to large amounts of captured data.

Waveform parameters such as voltage, frequency and RMS are measured automatically, and the instrument also incorporates facilities for internal computation of functions such as pulse count, single-cycle mode, linear scaling, "go/no-go" judgment, and user-defined mathematical calculations.

Other facilities include real-time recording to an optional hard drive, memory backup, "snapshot" and x-y displays, and an all-channel setup menu.

The 10.4in SVGA colour TFT liquid-crystal display (effective screen size 211.2 x 158.4mm) provides a resolution of up to 800 x 600pixel.

Floppy-disk, ZIP disk and PC card drives are available, as well as an optional 20Gbyte internal hard drive.

USB and Ethernet interfaces are available for connecting to an external PC or web server.

The DL750 ScopeCorder measures 355 x 250 x 180mm, and weighs approximately 6.6kg will full options.
