Hey,

I would like know if it is possible to use a calculated output in cross function ?

First, gain was calculated by out/in VF("/vo") / VF("/vi"). Then max value of the gain plot was tried to calculated by ''ymax'' function ymax(VF("/vo") / VF("/vi")). However it did not work. I used fist ''dbm'' to get dB equivalence dbm(VF("/vo") / VF("/vi")). Then ''ymax'' function was applied to dbm equivalence of gain ymax(dbm(VF("/vo") / VF("/vi"))). Numerical value was calculated correctly and shown in ''OUTPUT'' tab.

My problem is i would like to use that function which calculates this numerical value in cross function as cross(Gain_dB ymax(Gain_dB) 1 "either" nil nil )

Is it possible or is there a way to do what I want ?

I figured out how to use it :) I realised that ''cross'' function does not support fractional numbers as threshold value.
 

Yes, but it's difficult to get it right, typing it in. I usually
build up to it, saving snippets that work (i.e. give a value
that prints) into a scratch text file and then paste them
in appropriately, once proven. And I suppose you could
create cross-test-able vectors too, although I only work
with the raw voltages / currents as a rule. You might find
it a little less tricky to convert your dBm threshold to raw
volts or amps and test the node / port directly on that
basis.
