7.8 Sample Program
The following sample program was written in N88BASIC using the NEC PC-9801 as the controller.
For information on N88BASIC, refer to the instruction manual for the PC-9801.
(1) Simplest measuring method
Outline: This is the simplest measuring method using the MEASure command.
100 open "com1:n81nn" as #1
110 '
120 '
Performs measurement.
130 '
140 print #1,":measure:voltage:ac?"
AC voltage measurement in Auto Range
150 input #1,a$
160 print a$
170 close
180 end
(2) Setting up measurement conditions and loading measurement data
Outline: The system performs comparator setup, trigger setup, etc., and loads the measurement
values and comparator determinations.
100 open "com1:n81nn" as #1
