Eight-channel mixed-signal oscilloscope

Yokogawa (Japan) launched the DLM4000 eight-channel mixed-signal oscilloscope claiming to be the first device of this kind worldwide. The instrument is suited to test and debug applications in the embedded systems, power electronics, mechatronics and automotive sectors.

THE SERIES IS COMPRISED OF TWO MODELS with bandwidths of 350 MHz and 500 MHz and a sampling rate of 1,25 GSa/s (gigasamples per second), expandable to 2,5 GSa/s with interleaving. The inputs can be allocated as eight analog channels or seven analog channels, plus one 8-bit digital input. The devices feature a memory for up to 62,5 million points per channel (125 million points in interleave mode). A history memory function allows up to 20000 waveforms to be saved. These may be displayed one at a time, in order, or automatically played back, paused, fast-forwarded or rewound.
Measurement and analysis features include histogram and trending functions, digital filtering, zoom windows, user-defined mathematics and serial bus analysis. The oscilloscopes come with triggers combining analog and logic inputs such as edge, enhanced and B-triggers. These include dedicated trigger functions for CAN, Flexray, LIN, UART, I2C and SPI as well as the ability to perform simultaneous analysis on two different networks operating at different speeds. This capability is enhanced by search facilities, allowing to look for specific data in the memory.
The 6,5-kg devices incorporate a 12,1-inch XGA display and are housed in a 18-cm deep body. The display is enhanced by a fine grid, high luminance and viewing angle, and on-screen markers with simultaneous display of cursors and automatic parameters. Other features include backlit buttons, additional knobs and jog shuttle, on-screen information in diverse languages, two zoom windows, and a choice of first-cycle or screen average mode for frequency measurement.
