Trigger sweep, request data.
1. This command should normally be sent after START, STOP, and STEP to avoid delays
caused by rebuilding sweep when each command is sent.
2. For single sweep, trigger count should equal number of points in sweep: Points = (Stop-
Start)/Step + 1. You can use SOUR:SWE:POIN? query to read the number of points.
