Series of 8-channel mixed-signal oscilloscopes add 16 extra channels of logic and upgrade firmware for power measurements and serial-buses.
New enhancements to Yokogawa’s DLM4000 Series of 8-channel mixed-signal oscilloscopes allow more detailed analysis of embedded electronics. The L16 option adds 16 extra channels of logic to give seven channels of analog, plus 24-bit digital input. Upgraded firmware on the /G4 option for power measurements gives the oscilloscope enhanced power capabilities making it usable as a fully featured 3-phase power meter, with the eight channels allowing voltages and currents to be individually measured and displayed alongside derived values. The /F1 to /F6 options for serial-bus testing offers new firmware doubling the number of buses that can be simultaneously tested, such as four CAN, LIN or I2C buses or two SPI buses, plus one other, such as a UART interface. The DLM4000 Series is comprised of two models, with bandwidths of 350 and 500 MHz and a sampling rate of 1.25 GS/s, expandable to 2.5 GS/s with interleaving. The instruments feature up to 125 M points, 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.
