I am using mixer to upconvert baseband signal of 1-2 MHz to 2.4GHz.

I want to verify this upconverted signal before transmission.

I used ps to simulink block but with that it shows baseband signal only. I would like to know how can I verify that the signal is upconverted to passband signal?

Hello Rajashree,

To verify that your signal has been upconverted to 2.4 GHz before transmission, you can utilize the Spectrum Analyzer block in Simulink. Ensure that you configure the block to display a frequency range that encompasses both the baseband and RF signal frequencies. This setup will allow you to visually confirm the upconversion process by observing the signal's presence at the desired 2.4 GHz frequency.

Refer to the following documentation for more information:
