FRC Config

FRC Configuration is based on TS 38 521-1 V17.4.1 (2022-07).

You can manually set three parameters via GUI or SCPI (see below) while others are Internally Set Parameters.

GUI Parameter

Choices

FRC Type

FRC for receiver requirements for QPSK*

FRC for maximum input level for 64QAM

FRC for maximum input level for 256QAM

Bandwidth

FR1 10MHz*

FR1 20MHz

FR1 30MHz

FR1 40MHz

Subcarrier Spacing

15 kHz*

30 kHz

60 kHz

* default selection

SCPI Command

[:SOURce]:RADio:NV2X:WAVeform[:ARB]:CCARrier<carrier>:CONFig:FRC " FRCType:QPSK|QAM64|QAM256,
Bandwidth: FR1BW10M|FR1BW20M|FR1BW30M|FR1BW40M,
SubcarrierSpacing: SCS15K|SCS30K|SCS60K "

SCPI Example

RAD:NV2X:WAV:CCAR0:CONF:FRC " FRCType: QAM64, Bandwidth: FR1BW20M, SubcarrierSpacing: SCS30K "

Couplings

Parameters and default values of FRC are list below:

Bandwidth: FR1BW10M

FRCType: QPSK

SubcarrierSpacing: SCS15K

One combined string is required to be input into the SCPI command. The format is  "name: value , name: value …" .  Default value will be used if parameter is not provided.

The order of parameters does not matter. Parameter's name and value are case sensitive.

Internally Set Parameters

The parameters described in the table below are set by the software.
