15 Power Control Measurement
Index: n Results Returned
Measurement" selected, the slot averaged data trace (in dBm) is returned. (This data trace
corresponds to the ‘Result’ column in the Result window.) Number of slot is given as 1st
parameter in :MEASure:PCONTrol?.
4 PRACH Power result – returns comma-separated post-processed data Npreamble: Number of
PRACH Preamble
1st number: Pre-Burst Off Pwr (float, in dBm) of 1st PRACH preamble
2nd number: Burst On Pwr (float, in dBm) of 1st PRACH preamble
3rd number: Burst On Pwr relative to the previous data (float, in dB) of 1st PRACH (This returns
always 0.0)
4th number: Post-Burst Off Pwr (float, in dBm) of 1st PRACH preamble
5th number: Time Offset (float, in chip) of 1st PRACH preamble This returns always 0.0)
…
(N–1)*5+1: Pre-Burst Off Pwr (float, in dBm) of Nth PRACH preamble
(N–1)*5+2: Burst On Pwr (float, in dBm) of Nth PRACH preamble
(N–1)*5+3: Burst On Pwr relative to the previous data (float, in dB) of
Nth PRACH preamble
(N–1)*5+4: Post-Burst Off Pwr (float, in dBm) of Nth PRACH preamble
N*5: Time Offset (float, in chip) of Nth PRACH preamble
…
(Npreamble–1)*5+1: Pre-Burst Off Pwr (float, in dBm) of Npreambleth PRACH preamble
(Npreamble–1)*5+2: Burst On Pwr (float, in dBm) of Npreambleth PRACH preamble
(Npreamble–1)*5+3: Burst On Pwr relative to the previous data (float, in dB) of Npreambleth
PRACH preamble
(Npreamble–1)*5+4: Post-Burst Off Pwr (float, in dBm) of Npreambleth PRACH preamble
Npreamble*5: Time Offset (float, in chip) of Npreambleth PRACH preamble
Npreamble*5+1: Pre-Burst Off Pwr (float, in dBm) of PRACH Message (if available)
Npreamble*5+2: Burst On Pwr (float, in dBm) of PRACH Message (if available)
Npreamble*5+3: Burst On Pwr relative to the previous data (float, in dB) PRACH Message (if
available)
Npreamble*5+4: Post-Burst Off Pwr (float, in dBm) of PRACH Message (if available)
Npreamble*5+5: Time Offset (float, in chip) of PRACH Message (if available)
5 Slot Power Measurement trace (Relative Power measurement –1)
Returns comma-separated post-processed data trace for measured data. With "Slot Power
Measurement" selected, the relative power with the previous slot data trace (in dB) is returned.
(This data trace corresponds to the ‘Delta Adj Pwr’ column in the Result window.) The first data
returns always ‘0.0’.
The number of slot is given as 1st parameter in :MEASure:PCONTrol?.
6 Slot Power Measurement trace (Relative Power Measurement – 2)
Returns comma-separated post-processed data trace for measured data. With "Slot Power
Measurement" selected, the relative power level with the first slot (in dB) is returned. (This data
trace corresponds to the ‘Rel Pwr’ column in the Results window.) The first data returns always
‘0.0’.
