How to get scalar value out of a waveform?

[Thomas Ussmueller]

Dear all,

I am simulating phase noise of my oscillator. The output of the
PhaseNoise command is a waveform. I'd like to extract a value of the
y-axis at a given x-value. To be more precisely I'd like to get the
value of the phase noise at a offset frequency of 1 MHz.

I am looking for a function that returns a scalar out of the specified
waveform.

I have looked through the documentation, but I couldn't find a function
that would do this for me. Has anyone an idea how I could achieve this.

Thanks for your help and best regards

[S. Badel]

x = 1M
y = value(wave x)

should do it...

Thanks, that is exactly the function I have been looking for.
