a. If an 8340A is used, the 1.0 V/GHz output will have to be modified to a 0.5 V/GHz
output for proper display accuracy, leveling flatness, and harmonic suppression.
Provided with your mm-wave source module is a set of modification instructions.
This modification procedure will enable you to properly convert your 8340A to a
0.5 V/GHz output.
