RFmx WLAN SEM Sweeping Time "Auto" Setting

[Ting1224]

When set RFmx WLAN SEM sweeping time property to "Auto", the length of sweeping time is not long enough for 160/320M bandwidth to get a smooth SEM result for PA measurement. Making the sweeping time longer will get better SEM result. Customer wish RFmx WLAN tool could have the "Auto" sweep time value to be longer enough for better SEM results with PA in the loop.
