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
