Making a Measurement

Measurement Uncertainty

The uncertainty of any measurement includes several factors

related to the probe and meter.

Frequency response or frequency sensitivity is typically

±1 dB to ±2 dB (from about ±25% to about ±55%).

The correct use of correction factors can greatly reduce

the amount of uncertainty associated with frequency

response.
