Example Programs
The following is an example program using SCPI compatible
instruments. The example is written in HP BASIC.
This example is a stimulus and response application. It uses a source
and counter to test a voltage controlled oscillator.
Example Program
Description. This example demonstrates how several SCPI
instruments work together to perform a stimulus/response
measurement. This program measures the linearity of a voltage
controlled oscillator (VCO). A VCO is a device that outputs a
frequency proportional to an input signal level. Figure 1-28 shows
how the hardware is configured.
