how can I directly measure the cap or ind value in cds

I try to use the expression
imag(aaZP("PORT0" "PORT0))/freq
but failed ,because the frequency variable is not freq,my god!

heard that there is some direct way to measure the inductor or capacitor value,can anyone help me
or give me a valid expression.

beside what is the varible for temperature.
any somebody tell me how to reference the globale varibles

XVAL of any signal is:
Frequency for AC analysis
Time for Transient
Temp for DC if you sweep temperature.
So if you want to divide some signal by frequency divide that by XVAL of any signal of AC analysis.

I tried, the XVAL failed...
It seems that different version of cds use different variable quotation.

I don't think there is different variable quotation for different version.
I didn't undestand what does that mean
1. Here should be expression including VF or IF (It is supposed you run AC analysis if you want divide by FREQ).
2. Why only one quotation mark on the second PORT0. How did you enter this expression?
