A Enter the E4418A present frequency Reading (W).
B Enter the E4418A 10 MHz Reading (W).
C Apply power sensor correction factor for present frequency (W): CF * (Column A entry).
D Apply power sensor correction factor for 10 MHz (W): CF * (Column B entry).
E Compute and enter Error relative to 10 MHz (%): 100 * (sqrt(Column C entry) - sqrt(Column
D entry)) / sqrt(Column D entry).
