I am using the VTB component Tx_1Ant_Analysys an ADS 2016.01 and the MCS=0 1 and 2 shows an error :

error detected by HPEESOFSIM during circuit set up "VTB1_Env"

VTB exception occurred

Failed getting por datatype

 

With this log file:

Wifi_test_VTB_20MHz_MCS_0_VTB.log

If  I use MCS=3 there is not error and the log file is

Why I cant use MCS=0 or 1 or 2, BPSK or QPSK options?

 

Thanks in advance
