Option SCPI Description
Carrier Index
CINDex
Power of the specified carrier is the reference of measurement. Only the
frequency range of the specified carrier is swept and measured, and other
frequency ranges in the RFBW are not measured
If Measure Carriers of this carrier index is off, the reference power and all the
relative power results are NaN. Relative limits are not evaluated
Manual
MANual
Power or PSD specified by the user is the reference of measurement. No carriers
are measured and the manually specified value is used as reference
Max Power
Carrier in Sub-
block
MPCSubblock
Maximum carrier power among the sub-block carriers with Measure Carrier On
is the reference of measurement. All the configured carriers are measured
If Measure Carriers of all the carriers in a sub-block are off, the reference power
of the sub-block and all the relative power results referring to this sub-block are
NaN, and these relative limits are not evaluated
RF Bandwidth
RFBandwidth
Power or PSD of total of the RF bandwidth is the reference of measurement.
Power not only in the carrier bands but also carrier gaps is integrated into the
reference power. Measure Carrier On/Off does not affect the reference power
frequency range because RF bandwidth is determined by the carrier
configuration
Aggregated
Chan BW
LTE-A and 5G
NR Modes only
ACBandwidth
The assigned aggregated channel bandwidth power which is measured with a
rectangular filter with measurement bandwidth specified as aggregated channel
bandwidth based on the definition of each 3GPP standard. Calculated from the
carrier configuration including SCS (Power Meas), the smallest SCS among the
enabled SCSs of the selected component carrier. Measure Carrier On/Off affects
the reference power frequency range
If Measure Carriers of all the carriers are off, the reference power and all the
relative power results are NaN and Relative limits are not evaluated
Left & Right
Sub-blocks
5G NR Mode
only
LRSubblocks
The reference depends on the Number of Component Carriers (CC) and Carrier
Allocation as follows:
Number of CCs Reference
1 The carrier power is the reference
2 or more, and
Carrier
Allocation is
Contiguous
Aggregated Channel power is the reference
2 or more, and
Carrier
Allocation is
Non-
Contiguous
Aggregated powers of left and right sub-blocks are the
references. Left and right sub-blocks are determined by
component carrier configuration
The powers of carriers are not included in the reference power when their Measure
Carriers are Off. When Measure Carriers of all the carriers in a sub-block are Off, the
reference power and all the relative power results are NaN. Therefore, relative limits
are not evaluated.
