The CFR does not working properly

It looks like you have generated the CFR pulse for 2xNR100MHz carriers and enabled only one carrier of NR100MHz. That was the reason for getting the noisy spectrum after the enabled carrier. If you want to use this CFR pulse, you need to enable both carriers and the Info.BW on your Spectrum analyzer must be set to 200MHz.

Or, If you are enabling just one carrier, you need to generate CFR pulse for 1 carrier only.

Another observation is that you seem to be testing contiguous CA, you may still need to have the carrier offset of 50MHz (Not 49.14MHz- i think you have considered OBW of 98.28MHz/2) from LO or 100MHz from center to center of the carriers

I have tried the following configuration, but the same result.

The carrier frequency is centred around LO (freq = 0 was set)? Or the carrier is at -50MHz offset (Set freq= -50e6)?

Please go through the CFR generation application note.

The offset of carrier frequency from LO is zero.

Which profile are you using, is the Tx. input rate is 122.88MSPS? Pls share the CFR configset and CFR statistics? Whats the PAR of the input signal and whats the targeted PAR? Pls share the CCDF plots before and after CFR.

Which profile are you using, is the Tx. input rate is 122.88MSPS?

Pls share the CFR configset and CFR statistics?

Whats the PAR of the input signal and whats the targeted PAR?

the PAR of the input signal ：15dB

the targeted PAR：8.5dB

Pls share the CCDF plots before and after CFR.

the  CCDF plots before and after  are same，no change.

PAR of 15dB seems to be very high, which signal is this?

Can you increase the Peak threshold, what's the RMS input signal level (sorry, i missed to ask this previously)
