CPM (FM) Returns 4 comma-separated scalar values of the pass/fail (0.0 =
passed, or 1.0 = failed) results determined by testing the following
items:
1.
Pass/Fail result of Tx Power
2.
Pass/Fail result of RMS FSK Error
3.
Pass/Fail result of Frequency Error
4.
Pass/Fail result of Deviation Offset
2-ASK Returns 3 comma-separated scalar values of the pass/fail (0.0 =
passed, or 1.0 = failed) results determined by testing the following
items:
1.
Pass/Fail result of Tx Power
2.
Pass/Fail result of RMS ASK Error
3.
Pass/Fail result of Frequency Error
3.1.1.4 Measurement Results for RI = 06
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 Meas Time of Segment SI
Returns a series of floating point numbers that represent the data of the corrected measured trace
When "IQ Normalize" on page 347 is ON, the magnitude of the trace points are normalized to 1.0
2-ASK ASK Meas Time of Segment SI
Returns a series of floating point numbers that represent the data of the corrected measured trace
When "IQ Normalize" on page 347 is ON, the magnitude of the trace points are normalized to 1.0
All others IQ Meas Time of Segment SI
Returns a series of floating point numbers that alternately represent I and Q pairs of the corrected
measured trace
When "IQ Normalize" on page 347 is ON, the magnitude of the trace points are normalized to 1.0
The first number is the I sample of symbol 0 decision point and the second number is the Q sample of
symbol 0 decision point. There are X points per symbol (X = points/symbol). Therefore, the series of
numbers is:
–
1st number = I of the symbol 0 decision point
