Both passive and active high-voltage probes are available. To ensure safe operation, read the user's guide before using the probe. High voltage differential probes allow for safe and accurate floating signal measurements between two voltage points where neither point is referenced to ground. Enabled by high CMRR, a high voltage differential probe simplifies the measurement challenges found in noisy, high common-mode power electronics environments.
