Queries the Inner Loop Power measurements. Inner Loop Power Control consists of TPC (Transmit Power Control) commands that are sent to the UE on the downlink to control UE transmitter power on the uplink. This measurement verifies that the UE derives the transmitter power control command (TPC_cmd) correctly and that the inner loop power control drives the UE to the correct level relative to the adjacent timeslot. Inner Loop Power measurements are made over the period of time between 25 microsecond transient durations, which begin and end at the timeslot boundaries. The test set returns absolute and relative-to-previous values for each timeslot and performs aggregate power control measurements over 10 TPC_cmd groups. See FETCh:WILPower:TRACe:REL10TPC? Measurement results are returned in the following order (see Inner Loop Power Measurement Results ): |
|
|
Integrity (see Integrity Indicator ) Worst case slot number (based on each adjacent timeslot measurements) Absolute power (based on worst case adjacent timeslot measurements) Relative power (based on worst case adjacent timeslot measurements) Worst case slot number (based on worst case Rel Pwr 10 TPC (dB) measurements) Absolute power (based on worst case Rel Pwr 10 TPC (dB) measurements) Relative power (based on worst case Rel Pwr 10 TPC (dB) measurements) |

OUTPUT 714;"FETCh:WILPower?" ! Returns all Inner Loop Power control measurement results. |
|
|
Queries the measurement integrity indicator for the last measurement completed. Zero indicates a normal measurement. See Integrity Indicator for information about non-zero integrity results. |
|
OUTPUT 714;"FETCh:WILPower:INT?" !Returns the Inner Loop Power control integrity indicator |
|
| Returns the number of timeslots tested during the last Inner Loop Power control measurement. See Inner Loop Power Measurement Results . | |
OUTPUT 714;"FETCh:WILPower:NSLOts?" !Returns the number of slots tested. |
|
| Returns the absolute power levels of each timeslot measured during the last Inner Loop Power measurement. See Inner Loop Power Measurement Results . | |
|
Absolute power (for up to 150 timeslots, see FETCh:WILPower:NSLOts? ) |
|
OUTPUT 714;"FETCh:WILPower:TRACe?" !Returns the absolute power levels of all timeslots. |
|
| Returns the power levels of each timeslot measured during the last Inner Loop Power measurement relative to the adjacent, previous timeslot. See Inner Loop Power Measurement Results . | |
|
Relative power for up to 150 timeslots. See FETCh:WILPower:NSLOts? . |
|
OUTPUT 714;"FETCh:WILPower:TRACe:RELative?" !Returns the relative power levels of all timeslots. |
|
|
For each timeslot measured during the last Inner Loop Power measurement, returns the aggregate power level of the previous 10 TPC_cmd groups, relative to the first timeslot in a set of 10 TPC_cmd groups. TPC_cmd groups can occur at a rate of one group per timeslot (Algorithm One) or one group per five-timeslots (Algorithm Two). The first timeslot that has a 10 TPC measurement result will either be slot 10 (Algorithm One) or slot 50 (Algorithm Two). Timeslots are numbered beginning with zero. Depending on which algorithm is used and the number of timeslots tested, the number of results returned by this command will vary. See Inner Loop Power Measurement Results . |

Relative power (for up to 150 timeslots). See FETCh:WILPower:NSLOts? . |
|
OUTPUT 714;"FETCh:WILPower:TRACe:REL10TPC?" ! returns the aggregate power level of 10 TPC_cmd groups for ! each timeslot relative to the first timeslot ! in a set of 10 TPC_cmd groups. |
|
|
Returns relative power measurement pass/fail indications for each timeslot based on previous, adjacent timeslot power. See Inner Loop Power Measurement Results . Each pass/fail indication includes a result for both the adjacent and 10 TPC measurements. They are coded as follows: |

|
Pass/Fail (for up to 150 timeslots). See FETCh:WILPower:NSLOts? . |
|
OUTPUT 714;"FETCh:WILPower:TRACe:MASK?" !returns pass/fail indications for relative power measurements. |
|
| Returns the following measurement results in the following order for the timeslot number (timeslots are numbered beginning with 0) specified in the command (See Inner Loop Power Measurement Results ): | |
