Hi,
I am currently modelling an RF system using the RF blockset in Simulink. However, during simulation, I encountered the "delay history is too long" error when trying to use the "variable time delay" block to model the delay for a transmission line. The reason I am not using the "transmission line" block in RF blockset is that it is not tunable (the time delay cannot be varied during simulation).
System setup
Currently my delay is set to 1e-9 seconds, I tried values such as 1e-15 seconds but the error is still there. Interestingly, when I remove the variable attenuator and variable phase shifter, the system can simulate just fine.
Here is the error:
Here is the RF Configuration block setup:
Any help is appreciated. Thank you.
Raymond
