I am doing simulation in ADS 2013 for OIP3 (3rd order Intermodulation) and P1dB (1dB compression).
Attach below is my OIP3 Setup.
P1dB Setup
The problem is when I'm simulate both controller, there are warning:
"For source Port1, (1xFreq[2] = 2.001e+09 Hz) is 1e+06 Hz away from the closest analysis frequency at 2e+09 Hz. The maximum allowed frequency difference is 2000Hz."
To solve this warning, I add another Freq[2] is XdB simulator (HB3).
Is this the correct way to solve the warning? or I can just ignore the warning?
I won't have any problem when I run P1dB and OIP3 separately (means I activate only one simulator at time). But if I want to simulate both parameters at the same time, the error message pop-out.
I tried both of your opinions but the error is still there.
What else can I do? Does the error really affect the simulation result?
Hi Bigboss,

You can't do both simulation simultaneously.While one simulations is changing 2 carriers, other one should change single carrier only.
HB cannot discriminate which one is which..P1dB Compression Point simulation needs one single carrier at one single frequency but OIP3 needs 2 carriers ,,
Disable one simulation controller while the other is in progress.
