The length of the result depends on the number of available offset (See "Number of
Offsets" on page 1536)
k is an index for each offset: k = 0 for offset A; k = 1 for offset B; k = 2 for offset C, etc.
The number of offsets is 12 (A-L).
# Item
1 Depends on "Measurement Type" on page 1700:
–
Total power reference (dBm)
–
Power spectral density reference (dBm/Hz)
–
Spectrum peak power reference (dBm)
2 Reserved for future use, returns -999.0

1700 is Spectrum Peak Ref
3.9.4 Results for n = 6
When "Measurement Type" on page 1700 is Total Power Ref or PSD Ref, returns
comma-separated scalar values (in dBc or dBc/Hz) of the integrated power relative
to the carrier at the segment frequencies
When "Measurement Type" on page 1700 is Spectrum Peak Ref, returns comma-
separated scalar values (in dB) of the peak power relative to the carrier at the
segment frequencies
The length of the result depends on the number of available offset (See "Number of
Offsets" on page 1536)
For MSR, 5G NR, LTEAFDD, and LTEATDD Modes, returns outer offset results when
"Non-Contiguous Meas Region" on page 1622 is set to Outer or Outer & Inner
(5GNR, LTEAFDD, LTEATDD only), and returns inner offset results when it is set to
Inner
The results are in the following order:
