Yokogawa's DLM4000 is being touted as the industry’s only eight-channel mixed- signal oscilloscope. Combining the large screen and eight-channel capability of the company’s earlier eight-channel DL7480 oscilloscope with the mixed-signal technology of their DLM2000 Series, the new instrument is suited to test and debug applications in the embedded systems, power electronics, mechatronics and automotive sectors. The DLM4000 Series is comprised of two models with bandwidths of 350 and 500 MHz and a sampling rate of 1.25 GSa/s, 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 instruments feature up to 62.5 M points per channel and 125 M points in interleave mode, allowing both long recordings and multiple waveforms to be acquired. A history memory function allows up to 20,000 previously captured waveforms to be saved in the acquisition memory. The instruments incorporate a 12.1-inch high-resolution XGA display and are housed in a compact body less than 18 cm deep and weighing 6.5 kg.
