Multi-channel measurement application
Motor control & inverter circuit development
Limitation of 4 channel scope
Whole-system measurement is impossible with a four channel scope; the real difficulty is measuring the timing between IGBT gate signals within the inverter. Voltage and current measurements between 3 phases and the IO of the motor driver IC is a very challenging test with a four channel scope. The truly practical solution is an eight channel MSO.
Electronic control unite & mechatronic test
Limitation of 4 channel MSO
The additional logic inputs of a four-channel MSO mixed signal oscilloscope provides enough channels, but this method has a blind-spot. Digital waveform analysis using logic inputs alone cannot reveal anomalies such as voltage drift, noise, distortion or ringing, and measure rise-fall times. ECU testing requires stringent examination of all digital waveforms – and analogue input channels are the best tool for the job.
8 channels
The key to efficient and reliable high performance electric motors is the modern inverter design, or ‘Intelligent Power Module’. Multi-channel, highspeed waveform measurement is an absolute necessity. Four channels are simply not enough. Boasting eight true analogue inputs, the DLM5000 empowers today’s engineer with a convenient and comprehensive measurement system.
Numerous I/O analog, digital, and serial-bus waveforms surrounding the Electronic Control Unit (ECU) must be measured. The DLM5000 offers ample channel-count and architecture to monitor eight analogue channels and up to 24-bits of logic input while simultaneously performing protocol analysis such as UART, I2C, SPI, CAN, CAN FD, LIN, CXPI and FlexRay. The DLM5000 can speed up the R&D process when four channels are not enough.

Power supply analysis option (/G03)
Switching loss analysis
Calculate switching loss [V(t) × i(t)] over long test cycles utilizing the long built-in memory. A wide variety of switching loss analyses are supported, including turn-on/off loss calculation, loss including continuity loss, and loss over long cycles of 50 Hz/60 Hz power line.
Serial analysis function options (/F01 to /F05)
UART (RS232) /I2C/SPI/CAN/CAN FD/LIN/FlexRay/SENT/CXPI
Dedicated trigger and analysis options are available for various serial buses of both in-vehicle and embedded systems. Logic input can also be used for I2C/SPI/UART/SENT. When it is not necessary to observe waveform quality of a bus, decoding or analysis using logic inputs is possible.
Unique auto setup
Yokogawa’s proprietary auto setup function automatically analyzes the input signal and complex parameters such as bit rate and threshold level, selecting the optimal settings in seconds. This feature not only saves time but is also a powerful debugging feature when the bit rate and other parameters are unknown.
Simultaneous analysis of up to 4 buses
Perform high-speed simultaneous analysis on up to four different serial buses operating at different speeds. Extensive search capabilities enhance the usability, allowing the user to find specific data in the very long memory. The dual-zoom facility means that different buses can be viewed and debugged alongside each other.
