How to measure conduction angle in ADS for Power Amplifiers?

Friends,

I would like to measure conduction angle of my PA. I found a ADS simulation file from Keysight. They have measured the conduction angle in that file, but when I try to use the equations, I cannot see the result. The point is when I type "freq[1]" which is frequency (first harmonic), the equations become red, which means they are not true!
Do you have any idea?

What analysis do you use ?
Do you use HB ?
Show me content list of your "*.ds* file.

In your data display, m1 and m2 don't exist.
Show me result of what(vddd) and what(Iddd.i).

Thank you for your help.
Yes, I am using HB. I am trying to see inside of the ".ds" file. How can I open it?!




Sorry, you are right. I editted the photo!

In your data display, m1 and m2 don't exist.

t1=indep(m6)
t2=indep(m7)
toff1=(t2-t1)*freq[1]
cond_angle=360*(1-toff1[0])

Show me result of followings.
List what(vddd)
List what(I_ddd.i)
List what(toff1)

freq[1] is short name.
It might be required for full name.

Show me list content of "*.ds" or ADS netlist.

I tried to read it but I faced an error: "read failed"
I uploaded my design. Could you please take a look on that?My schematic NewDesign2

Simply rerun simulation.
Then show me ADS netlist.

If so, how to plot ts(vddd) and ts(I_ddd.i) ?

I think this is the netlist:

An HB truncation error may be present.
o The HB truncation error is due to using a finite order
(number of harmonics) in the representation of the
circuit signals.

o The maximal HB truncation error estimate is greater than the

o To reduce the error, increase the order (number of harmonics)
and re-simulate.

No, this is not netlist.
Surely read my append.

You run multiple analyses at once.
At least, two freq exist in your "*.ds".
One is for SP1, the other is for HB1.
So you have to specify full name.
HB1.HB.freq[1] or HB.HB1.freq[1]

Show me content list of "*.ds" or ADS netlist.

I turned off s-parameters simulator and just used HB. It worked!
But value for conduction angle is weird! 720 degree!

Simply your equation for conduction angle is completely wrong.

HaHaHa!

The equation is not mine! This is from keysight!

Don't believe anything blindly.

change t2-t1 to t1-t2.
