Adalm Pluto problems with lab1 and lab2

Hello, i am not able to get the signal on th spectrum analyzer in lab1. The signal is not the same. I tried to modify the settings but the signal looks differnt and the gain is not the same. I followed the same direction and guidance provided. Also, lab2, for the AM signal lab2 folder has two m files and some simulink models. i don't see ADALM-PLUTO model instead i see USRP and RTLSDR. which model can i use for my kit to implement lab2?

Your help is appreciated.
