Modulation Accuracy (Composite Rho)
5 Corrected measured trace – returns series of floating point numbers that alternately represent I
and Q pairs of the corrected measured trace. The magnitude of each I and Q pair 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/chip).
Therefore, the series of numbers is:
1st number = I of the symbol 0 decision point
2nd number = Q of the symbol 0 decision point
…
(2*X)+1 number = I of the symbol 1 decision point
(2*X)+2 number = Q of the symbol 1 decision point
…
(2*X)*N+1 th number = I of the symbol N decision point
(2*X)*N+2 th number = Q of the symbol N decision point
6 Returns 6 scalar values of the pass/fail (0=passed, or 1=failed) results determined by testing the
EVM, the peak EVM, Rho, the peak code domain error, the time offset, and the phase error.
7 Returns series of floating point numbers of code level, code index, power
(in dB), time offset (in ns), phase offset (in rad), and code domain error
(in dB). The total number of results are six times of “number of active
channels”. The number of active channels can be obtained by the 10th
result of READ:RHO1 command.
