N5173B Power search failed. Power Unleveled.

Question asked by lu_ on Nov 20, 2015
Hi everyone !
I'm using the N5173B to generate RF pulse in a certain frequency range. 
The ALC is turned off because the pulse is very short.
While I scan the frequency by Labview, sometimes there is an error
Instrument reports:
+632,"Power search failed. Power Unleveled."
+0,"No error"

and I get no output.

Does anyone have suggestions ?
