3. In Table 1-3, transfer the 10 dB error value located within the
parenthesis in column B to each space in column C.
4. The values in column D result from changing the reference
attenuation of the calibration data of the 8496A to 10 dB.
Calculate the attenuation error values for this column by subtracting
the values in column C from the values in column B (B − C = D).
5. The values in column F result from correcting the expected
measurement value by the amount of attenuator error.
Calculate the attenuation error values for this column by subtracting
the values in column D from the values in column E (E − D = F).
6. Transfer the values from column F in Table 1-3 to column F in the
performance test record for both ports.
