Specifications (Continued) Effect of time-gating and averaging on normal mode measurement noise: The normal mode measurement noise wil depend on the gate length (time-gated period in second) and the number of averages. The noise can be approximately calculated with the following equations. If the gate length is < 2.73 µs, use Equation 1: Noise = Noise per sample × 1 Number of averages Otherwise, use Equation 2: Noise = Noise per sample × 1 Number of averages × ( 4 Gate length/(0.

Specifications (Continued) Calibration factor and reflection coefficient Calibration factor (CF) and reflection coefficient (Rho) data is unique to each sensor. The CF corrects for the frequency response of the sensor. The reflection coefficient (Rho or ρ) relates to the SWR based on the following formula: SWR = 1 + ρ 1–ρ Maximum uncertainties of the CF data are listed in the following table. There is only one set of CF data used for both high and low power paths of each sensor.
