Measurement Applications (Sample Programs)
Sorting Measurement Results Using Comparator
Sorting Measurement Results Using Comparator
This application program sorts the measurement results using the comparator
function.
The program of Example 9-14 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 comparator limit values for
Bin1,Bin2 and Bin3 of the E4981A. Sets the trigger
conditions of the E4981A.
Measurement Enables Bin 1 to 3. Disables Bin 4 to 9. Reads measurement
values using *TRG command fifty times. Displays the bin
values.
Setup End Closes the I/O bus.
ErrorProc Displays an error number when an error occurs.
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.
