3.1.1.8 Measurement Results for RI = 10
TThe 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)
FSK Error Time of Segment SI
Returns a series of floating point numbers (in percent) that represent each sample in the FSK Error Time
trace
When "IQ Normalize" on page 347 is ON, the trace points are normalized
2-ASK ASK Error Time of Segment SI
Returns a series of floating point numbers (in percent) that represent each sample in the ASK Error Time
trace
When "IQ Normalize" on page 347 is ON, the trace points are normalized
All others Error Vector Time of Segment SI
Returns a series of floating point numbers (in percent) that represent each sample in the EVM 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, … and so on
When "IQ Normalize" on page 347 is ON, the trace points are normalized
3.1.1.9 Measurement Results for RI = 11
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)
FSK Error Spectrum of Segment SI
Returns the spectrum of the FSK Error Time trace
When "IQ Normalize" on page 347 is ON, the trace points are normalized
2-ASK ASK Error Spectrum of Segment SI
Returns the spectrum of the ASK Error Time trace
When "IQ Normalize" on page 347 is ON, the trace points are normalized
All others EVM Spectrum of Segment SI
Returns the spectrum of the error vector time trace
When "IQ Normalize" on page 347 is ON, the trace points are normalized
