Procedure
NOTE These adjustments need only be done under the following conditions:
Limiter phase Only if a repair is made to blocks F, G, H, I, or J.
Linear fidelity Only if a repair is made to blocks C, D, F, G, H, I, J, K,
O, IF gain accuracy, RBW switching, or log fidelity.
Log fidelity Only if a repair is made to blocks D, F, H, K, IF gain
accuracy, RBW switching, or log fidelity.
