Lines 20 to 70: Declare variables and I/O paths for instruments. I/O paths let
you use a name for an instrument m OUTPUT and ENTER statements, instead

Assign values to the input test limits in mV.
Clear the instrument HP-LB interfaces.
Reset each instrument to a known measurement state.
Query measurement instruments' identikations for test
traceability.
Connect the source output signal to the output terminals.
Print results table header.
This is the main measurement loop. Line 400 contains two
commands. : SOUFtce : VOLT sets the output level of the source.
finished executing. To make an accurate measurement, the
source output must be allowed to settle. When the output has
settled, *OPC? places a 1 in the source Output Queue. The
program waits at line 410 until the 1 returned by *OPC? is
entered.
Note that following each OUTPUT containing a query is an
ENTER to retrieve the queried value. If you do not use paired
OUTPUT and ENTERs, you can overwrite data in the instrument
S
Output Queue and generate instrument errors.
Disconnect output terminals of the instruments from the unit
under test, and end the program. All HP BASIC programs must
have END as the last statement of the main program.
