6-74. SC600 Hardware Adjustments

Hardware adjustments must be made to the leveled sine and edge functions each time the
SC600 is repaired. In addition to the adjustment procedures, this section provides lists of
the required equipment and some recommendations on models that have the capabilities
required by these procedures. Equivalent models can be substituted if necessary.

6-75. Equipment Required

The following equipment is necessary for performing the hardware adjustments
described in this section. The models listed are recommended for providing accurate
results.

6-76. Adjusting the Leveled Sine Wave Function

There are two adjustment procedures that need to be made for the leveled sine wave
function. The first procedure adjusts the balance out of the LO VCO so that the signal is
balanced between the two VCOs. The second procedure adjusts the harmonics.
