4.2.12 Configuring demodulation parameters

Access: "Overview" > "Demodulation"
Demodulation settings contain settings that describe signal processing and the way the
signal is measured.
The remote commands required to configure the demodulation are described in
ter 6.9.2.7,
Multicarrier
Scrambling of Coded
EVM Calculation
NPDSCH Reference
Compensate
Multicarrier Filter
Turns the suppression of interference of neighboring carriers for tests on multiradio
base stations on and off (e.g. LTE, WCDMA, GSM etc.).
The FSW automatically selects the multicarrier filter when you analyze more than 1
component carrier.
Remote command:
[SENSe:][LTE:]DL:DEMod:MCFilter
Scrambling of Coded Bits
Turns the scrambling of coded bits for all physical channels like NPDSCH on and off.
The scrambling of coded bits affects the bitstream results.
Remote command:
[SENSe:][LTE:]DL:DEMod:CBSCrambling
EVM Calculation Method
Selects the way the EVM is calculated.

Calculates the EVM according to 3GPP TS 36.141. Evaluates the
EVM at two trial timing positions and then uses the higher EVM of the
two.
