Modulation analysis

1.

For the N/W9077A application, these values are found in the “numeric results” trace under the modulation analysis view. For 89601B with Option B7R and

Option BHJ, these values are found under the “Syms/Errs” trace.

2.

The standard describes the procedure for making this measurement, but doesn’t specify test limits.
