NOTE In addition to the sweep completion bit, another bit is provided separately to indicate the
completion of data measurements for adapter setting, user calibration, and fixture
compensation. To detect the completion of these measurements, enable Bit 8 in the
instrument event status register.

Identifies the external controller and Instrument BASIC and sets the
GPIB address and the select code.
Sets the trigger source to the internal trigger and sets the sweep
averaging factor to 4.
Enables Bit 0 (sweep completion bit) in the instrument event status
register and sets Bit 2 in the service request enable register to 1.
Clears the status byte register and the instrument event status register.
Sets the branch destination for the SRQ interrupt and enables the SRQ
interrupt can be used.
Executes the command to perform four sweeps.
Waits for the completion of the sweeps.
Displays the sweep completion message.
