Pulsed Sources in Keysight ADS

[HariHerekar]

Hey all,

I plan to simulate the effect of pulsed Drain-Source voltage on a GANFET model. Basically i would like to apply a simple DC Pulse train to the Drain-Source terminal and measure the ID and VDS.
The problem is that ADS treats sources like VtPulse as a short circuit during DC simulations. I dont want to perform a transient simulation, rather a DC one by sweeping VDS and plotting against ID.
Any ideas how I can achieve this ?

VtPulse is a time domain (transient simulation) source. Behaviour in other simulation modes can be set by additional simulation sources in series with VtPulse.

Pulse source has DC, tran initial and pulse levels in all the SPICEs I've used. It would seem peculiar to not have legacy source params.

For initial conditions to be useful the DC and initial values should be the same.

ADS isn't SPICE. VtPulse source has definitely no DC or AC parameters.

I would like to use the Pulsed DC source (Vtpulse), to do a DC simulation. But in the DC simulator, time dependent sources such as Vt pulse are treated as short circuits.
Any idea how i could combine sources so that i can do a DC sim with a Pulsed DC source ?

There are no time variant signals in DC analysis. Please explain what you want to achieve. What shall be the purpose of pulsed source?
