E4440A Alignment

sometimes the PSA performs automatic alignment, i do not know what cause it but it seems PSA stops everything during the alignment. My problem is the alignment makes my remote control software dead to no response when sending SCPI command or taking weep for measurements.

what is the solution for this problem?
do i have to query the PSA status before sending any SPCI command? How do i know the alignment has been completed(SCPI over GPIB)?
