Hi, I am trying to simulate s2p model using a template sch provided with “simulation_SParameter.qucs” from examples webpage. From the template I deleted all components. I have only input port, s2p file, output port. The simulation is configured as 1-5GHz with 5 point and noise sim enabled. As an s2p model I use BFU725F_2V_5mA_S_N.s2p downloaded from NXP website. Problem nr 1: the simulation fails with the model file BFU725F_2V_5mA_S_N.s2p. However the simulation runs fine when I remove the noise...

You need to add a new line character at the end of your s2p file. Just open the s2p file in a text editor and press "enter" once or twice at the end of your file.
