acquired with the PCI-Lockin in LabView. The user provides the corner data for the spectra
acquisition (Start Frequency, Stop Frequency, Number of Values). When the VI-file runs, one
spectrum is acquired. The data values are set here with units. The Output Amplitude in this front
panel equals the Amplitude in the Input_LockIn.vi. During the spectra acquisition, the current
frequency is monitored.

Switch into the diagram view of the vi-files. The parameters are set and read with the
DLL functions or double click into these functions to open the window, which allows
to correlate the function with a DLL-function and its exchange value:
The used library is the 'lockin.-dll'. The example sets the frequency with the function
'SetLockInFreq'.
The value is of numerical type and 8-Byte Double long.
