3.1 Digital Demod Measurement
3.1.1.10 Measurement Results for RI = 12
The FETCh, MEASure, or READ queries return the following comma-separated scalar
results for Segment SI. For values of SI, see "Index Sub-Fields" on page 184.
For details of available formats, see "Modulation Format" on page 335.

CPM (FM)
Carrier Mag Error of Segment SI
Returns a series of floating point numbers (in percent) that represent each sample in the Carrier
Magnitude Error trace
When "IQ Normalize" on page 347 is ON, the trace points are normalized
2-ASK Reserved
All others Magnitude Error of Segment SI
Returns a series of floating point numbers (in percent) that represent each sample in the magnitude
error trace. The first number is the symbol 0 decision point. There are X points per symbol (X =
points/symbol). Therefore, the decision points are at 0, 1*X, 2*X, …
When "IQ Normalize" on page 347 is ON, the trace points are normalized

All others Phase Error of Segment SI
Returns a series of floating point numbers (in percent) that represent each sample in the phase error
trace. The first number is the symbol 0 decision point. There are X points per symbol (X = points/symbol).
Therefore, the decision points are at 0, 1*X, 2*X, …
3.1.1.12 Measurement Results for RI = 14
The FETCh, MEASure, or READ queries return the following comma-separated scalar
results for Segment SI. For values of SI, see "Index Sub-Fields" on page 184.
