Combined Measurement Example
This program combines three major tasks that you would use when making
measurements when controlling the oscilloscope card over the bus. The
three major tasks are initializing the interface and oscilloscope card, digitizing
the acquired signal, and measuring and printing the frequency and
peak-to-peak voltage. This program is written with subroutines in HP BASIC
6.2.
