Stimulus settings exceeded the params of original cal

Hi,

I'm currently writing a program based on the TwoPortGuidedCal from the PNA example, with a power cal (at a single power), receiver leveling.
Once the calibration is done, the program proceeds to making a power measurement, Pout vs Pin, over a range of frequencies
(that creates a bunch of files, each at a fixed frequency, with Pout vs Pin).

The issue I have is that the PNA notifies me that:
"
Stimulus settings for your current instrument state
exceeded the parameters of the original calibration, so
correction has been turned off

"

I get this before I can even enter the start power of the power sweep.
Anybody has an idea where that comes from?

Thank you,
