Program Comments
10: Assign the source's HP-IB address to a variable.
20 to 50: Abort any HP-IB activity and initialize the HP-IB
interface.
60: Clear the computer's display.
70: Set the source to its initial state for programming.
80: Set the source up for a sweep, from 4 GHz to 5 GHz.
90: Set the sweep time to 2 seconds. In SCPI, suffixes are optional
if you program in fundamental units (for sweep time, that would
be seconds).
100: Send an 'OPC? to the source.
110: Enter the query response to the *OPC? into a variable "X".
The program execution will halt here until the source has finished
processing all the commands up to this point. Once complete, the
source will respond to the *OPC? with a "1".
120: Begin a FOR/NEXT loop that is repeated four times.
130: Initiate a sweep on the source.
