23. Calculate the desired maximum marker amplitude reading as follows:

a.Add the Frequency Response Error (FRE) to 060 dBc (speci￿cation is 0100 dBc, but reference level will be changed by 40 dB to yield the required dynamic range), then record as the Distortion-limited Speci￿cation in Table 2-47.

Distortion-limited Speci￿cation = 060 dBc + FRE

b.Subtract 67 dB￿V (reference level setting) from Noise Level at 5.6 GHz, then record in Table 2-47.

Noise-limited Speci￿cation = Noise Level at 5.6 GHz 0 67 dB￿V
