Easy Measurements for High-Speed, High-Voltage Electronics

  • Measure non-grounded (floating) signals in applications such as inverters, motors, and power supplies
  • Especially useful for high-speed high-voltage switching operations of SiC and GaN devices
  • Feature a versatile BNC interface, allowing seamless use with a wide range of general-purpose oscilloscopes
  • Either a DLM series probe power supply option (/P2, /P4, or /P8) or the separately sold probe power supply (701934) is required
  • Expanded range of optional accessories according to the measurement target
  • Combine with a high-definition oscilloscope (like DLM3000HD  or DLM5000HD) for more accurate waveform measurements
