This is a statistical power measurement of the complimentary
cumulative distribution function (CCDF). You must be in the Basic,
cdma2000, W-CDMA (3GPP), or W-CDMA (Trial & Arib) mode to use
these commands. Use INSTrument:SELect to set the mode.
The general functionality of CONFigure, FETCh, MEASure, and READ

even-indexed values. The Q values are the odd-indexed values,
not specified or
n=1
Returns 10 comma-separated scalar results:
1. Average input power (in dBm)
2. Probability at the average input power level (in %)
3. Power level that has 10% of the power
4. Power level that has 1% of the power
5. Power level that has 0.1% of the power
6. Power level that has 0.01% of the power
7. Power level that has 0.001% of the power
