320 to 330: Connect the source output signal to the output
terminals.
340 to 380: Print results table header.
390 to 460: This is the main measurement lo op. Line 400 contains
two commands.
:SOURce:VOLT
sets the output level of the source.
*OPC?
is used to signal that the preceding command has nished
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
s and
ENTER
s, you can overwrite data in the instrument Output Queue and
generate instrument errors.
470 to 480: 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.
