Accurate 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 IGBTs and SiC devices
- Attenuation ratio can be selected, automatically recognized, and configured (along with the input impedance setting) to help prevent setting errors
- No separate power supply is required, which allows for immediate measurement after connection
- 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
