Hi

I am trying to frequency response estimation of a dc-dc converter which has 50 Khz switching frequency. I am getting the following error

??? Error using ==> frestimate>LocalCheckDataTypeAndSampleTime at 729
In "frestimate(modelname,op,io,in)", it is required for each of the
linearization input I/O points that the sample time of the Simulink signal
where it is located is one of the following:
1. It is either continuous or fixed in minor time step.
2. Its sample rate is equal to the sample rate of the input signal "in".
The linearization I/O io(1) does not satisfy this requirement. Consider
either changing the sample time of Simulink signal where io(1) is located
to continuous sample time or changing the sample time of input signal "in".

I tried sample time of 2e-6 for solver .

What should be done in order to rectify this .Thanks in advance
