I am having the "Meas Uncal" from N9010A EXA while testing radiated emissions. The remote setting was from ETS-Lindgren's TILE6! program as following: 
QP measurement in zero span, RBW=120kHz, VBW=300kHz, sweep=200 ms (10001pts). 

When changed sweep = auto from Tile6!, EXA displayed sweep = 269 seconds (If I remembered correctly). Tile6! application treated the long sweep as no response and terminated its operation. 
When set sweep = 200 seconds, still got "Meas Uncal". I could not stand to try any longer sweep. 

Thank you for any advise in advance.
