sampling Frequency in Simulink NCO

[alzomor]

Hi

I am using simulink NCO
I can't find in help or in dialog boxes for the NCO , I can't find how to set the Sampling frequency Fs for the NCO

Do you know How to set it?

Hi

I have discovered it.
In the function block parameters
if I select the "Phase increment source = input port" there's no dialog box for sample time

but I select "Phase increment source = specify via dialog " the dialog box for sample time appears and I can set the sample time

Is there any reason , or it's a bug?

Thanks

Hi

After some search I found the following data in the NCO help
"
Sample time:Specify the sample time in seconds when the block is acting as a source.
When either the phase increment or phase offset come in via block input ports,
the sample time is inherited and this parameter is not visible.
Samples per frame:Specify the number of samples per frame when the number of samples per frame is greater than one. When it exists, the phase offset input port has
the same frame status as the output port(s). The phase increment input port,
when it exists, does not support frames.
"
but why?

and how it's inherited? and inherited from what?
