Load pull contour plot error

Martinsh

Dear Sir,

Run Load pull simulation:

1) HB simulation with sweeping input power (Pin)

2) Setup portAdaptor with Mag and Phase sweep

After simulatoin, saturated power is got with equation:

Psat = value(Pout lastVal(Pout))

So, Psat is a two dementional parameter and it relates to the Mag and Phase of load impedance.

But when I plot a contour with following function, error is reported.

awvRfLoadPull(Psat ?maxValue nil ?minValue nil ?numCont 8 ?closeCont t)

It says, 

*Error* awvRfLoadPull can handle two or three dimension sweep results only

ERROR (VIVA-3002):expression evaluation failed: Expression evaluates to nil
ERROR (VIVA-3002):expression evaluation failed: awvRfLoadPull(Psat ?maxValue nil ?minValue nil ?numCont 8 ?closeCont t)

If I plot Psat directly, it's OK. What's wrong with this contour plot method?

Regards,

Martin
