Notes Some modes do not support Carrier subopcode 2. In those cases, commands with subopcode 2 are
accepted without error but ignored
For LTEAFDD or LTEATDD Modes, this control is not shown. In order to maintain backwards compat-
ibility with legacy LTE FDD/TDD, the SCPI command is supported in LTE & LTE-A converged applic-
ations
Couplings When ON, the carrier settings are coupled to carrier #1. Coupled parameters are: Carrier Power
Present, Carrier Spacing, Measurement Noise Bandwidth, Method and Filter Alpha
When a setting is changed, coupling is switched off automatically
Carrier #1 is always set to ON and cannot be changed
Preset
ON
State Saved Saved in instrument state
Carrier Pwr Present
Configures the carriers for this measurement. Allows spaces to be inserted between
carriers. Carriers with the power present parameter set to YES are carriers, and
those with the power present parameter set to NO are spaces. Each carrier power
present is set to YES or NO. The individual carrier can be set by selecting the desired
carrier.
The query returns the current values for all of the carriers. If a carrier is defined as
having no power present, the power displayed is relative to the reference carrier,
otherwise the absolute power is displayed.
If you change the carrier power present to NO, and that carrier is currently
configured as the reference carrier, the next carrier to the left (or the right if there
are no carriers to the left) is assigned as the reference carrier. This also applies to
the scenario where there are only two carriers configured as having power present,
and you configure only one carrier to have no power present.
