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 is described in detail below. Each explanation
below is inserted as a comment line in the program. For details on the VISA
functions, refer to the I/O Library Suite manual.
Configuration Define Variables and initialize the program.
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 E4981A and a PC.
