Cannot use erdes AGC block

I can't use AGC block in serdes toolbox, when I click serdes AGC block error appears -->Error evaluating 'PreCopyFcn' callback of AGC block (mask) 'QPSK/AGC'.

Callback string is 'serdes.internal.callbacks.datapathPreCopy(gcb);'

-->'QPSK/AGC' must reside in a top-level Tx or Rx subsystem within a model produced by SerDes Designer.

I have installed SerDes toolbox. Can anyone help me fix the above error

Hi @Nhut,

As per my understanding, this is working as designed. The block will not function correctly in a non-SerDes Simulink model thus giving hard error.

I also saw on YouTube that other people also use AGC blocks. I'm simulating a signal with qpsk modulation with transmit and receive using adalm-pluto, I want to use the Auto Gain Control block but can't use it, so can you help me with which block can replace it? Thanks
