Changing the LO on HP8970B

Does anyone know if you can change the LO frequency while in a 1.4 measurement mode without affecting the calibration?  From what I can tell as long as I don't change the start, stop, step or freq increment it should be ok.

I want to use multiple LNBs to make a noise temp measurement without recalibrating between each set of measurements.  I'm just making a couple of hot/cold measurements so I'm only interested in the delta anyways.
