Usage

Utility

owonpds [filename]

Print information about the scope data and optionally save it to a CSV or PNG file depending on the scope mode.

Python

An Python test script 'owon_scope.py' is included in the 'src/' directory to display vector data from the scope

C Library

void main(void){
    OWON_SCOPE_T scope;
    owon_open(&scope, 0); // Success if zero
    owon_read(&scope);    // Success if zero
    /* scope structure now holds captured data
     * do something with it and maybe owon_read() again...
     */
    owon_close(&scope);
}

Python Wrapper

import libowonscope

def main:
    scopeObj = libowonpds.OwonPds()
    scopeObj.open() # Success if zero
    scopeObj.read() # Success if zero
    data = scopeObj.get_scope()
    # data holds the captured data
    # owon_read() again or
    scopeObj.close()

Known Limitations

• Streaming data is not available, the incoming data is not time-stamped.
• Polling faster than 7Hz causes the oscilloscope to reboot after a while (PDS5022S - W5022S08530496 v4.1)
