Oscillator Simulation in ADS!

[dopradar]

Hi all,

Please help me solve this simulation problem of 3rd overtone oscillator in ADS. It can't work in the ADS simulation. and I am attaching the project in the following. Thanks in advance!

it worked now with me

what i have done ?

1 ) the frequency setting the fundamental is 72 MHz
2) i changed the output node " the collector not the emitter"
3) changed the direction of the of oscillation probe

i will upload the modified project

Thanks, Khouly.

But here I also have some questions:

1) why the frequency setting is 72MHz not 24MHz? because the resonant RLC works at about 24MHz, I want to watch the harmonics amplitude of 24MHz.

2) why the output node is "collector" not "emitter"? Because on the PCB circult, the output from emitter can work but output from collector can't work.
Note: on the PCB circuit,I replace the C1,C2,L1,R2 to 24MHz crystal!
