Reading Measurement Results in Binary Format Using :FETCh? Command

Reading Measurement Results in Binary Format Using
:FETCh? Command
This application program reads measurement data in Binary format using the :FETCh?
command.
The program of Example 9-9
inserted as a comment line in the program. For details on the VISA functions, refer to the

Open Instrument Assigns a USB address or GPIB address to the I/O bus.
Setup Start Presets the E4981A. Sets the trigger conditions of the E4981A.
Measurement Reads the measurement data using the :FETCh? command, calls the
function to convert data in Binary format to Ascii format, and displays
the Primary and Secondary Measurement data.
Setup End Closes the I/O bus.
ErrorProc Displays an error number when an error occurs.
Binary Read A subroutine to convert Binary format data to Ascii format.
ErrorCheck A subroutine to check whether an error occurs when the IO Library
Suite function is executed.
SelectMode A subroutine to change assignment of the I/O bus and address setting
according to the connection type i.e. USB or GPIB between the
