The new DL750 ScopeCorder from Yokogawa is said to be a truly portable waveform measuring instrument that combines recorder and oscilloscope technologies (Plate 8).
The instruments exceptional memory length of up to one gigaword coupled with 10 MS/s sampling is thought to make it ideally suited to the capture and analysis of high-speed signals over long time periods of up to 10 days.

The DL750 ScopeCorder can reportedly 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 1 Gword of data stored in the memory and display it virtually instantaneously.
The instrument can capture data on up to 16 analogue channels plus one 16 bit logic input. Data is sampled at up to 10 MS/s with 12 bits AID resolution via a two-channel isolated input module, or at 1 MS/s at 16 bits using a high-sensitivity (1 mV/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 claimed include real-time recording to an optional hard drive, memory backup, “snapshot” and XN displays, and an all-channel setup menu. The 10.4 in. SVGA colour TFT liquid crystal display (effective screen size 211.2 × 158.4 mm) provides a resolution of up to 800 ×600 pixels.
Floppy-disk, ZIP disk and PC card drives are available, as well as an optional 20 Gb internal hard drive. USB and Ethernet interfaces are available for connecting to a external PC or web server.
The DL750 ScopeCorder measures 355 × 250 × 180 mm, and weighs approximately 6.6 kg with full options.
