1. These commands are not required in this case, since unit assumes these operating
states after *RST but are included to demonstrate complete programming steps.
2. 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.
3. This command should normally be sent after START, STOP, and STEP to avoid
delays caused by rebuilding sweep when each command is sent.
