ADAPTIVE POWER MEASUREMENT ACCUMULATOR WITH A CHANGING SAMPLING FREQUENCY

A power meter includes a sampling circuit configured to initially make electrical measurements of a unit under test at a first sampling frequency. The power meter includes an adaptive circuit. The power meter includes an accumulator configured to accumulate electrical measurements of the unit under test from the sampling circuit. After a change in sampling frequency from the first sampling frequency to a second sampling frequency, the sampling circuit makes second electrical measurements at the second sampling frequency. The adaptive circuit is configured to adjust the second electrical measurements from the sampling circuit according to a factor. The factor is based on a relationship between the first sampling frequency and the second sampling frequency. The adjustment yields adjusted second electrical measurements. The accumulator is further configured to accumulate the adjusted second electrical measurements. 一种功率表，其包括采样电路，该采样电路被配置为初始地在第一采样频率下获得待测单元的电测量结果。该功率表包括自适应电路。该功率表包括累加器，该累加器被配置为累加来自采样电路的待测单元的电测量结果。在
