Keysight E4980A/AL Precision LCR Meter 295
Sample Program
Read Measurement Results
Read measurement data in BINARY (comparator)
This application program reads the measurement data in BINARY format when
the comparator function is on.
The program of Example 9-6 is described below.
Configuration Assigns variables and enables error handling by the
subroutine named ErrorHandler
Open Instrument Assigns a USB address or GPIB address to the I/O bus. Also
sets the time for timeout.
Setup Start Sets the trigger, comparator function, and data format.
Meas Read Reads the measurement data using the :FETCh? command
and displays the returned BINARY format array data
individually.
Setup End Close the I/O bus.
ErrorProc Displays an error number when an error occurs.
BinaryAry Read Sets the address of the array in which measured data is
stored. A subroutine to set the returned BINARY format data
in the array.
Example 9-6 Read measurement results (BINARY format, comparator)
