The SubVI
GetUnitAndRangeFromString.vi
cuts a string consisting of value and unit into these
two parts. The value from this operation (Range) is divided by the physical gain that is supplied by
the physical unit (e.g. PhysGain is 1000 for a PhysUnit of “mV”). The count of digits to be shown in
“SetAUX_Lockin.vi” is calculated in the second part of the VI. It depends on the Range of the
supplied String.
The VI “
Nase_LockIn.vi
” (in LabView9 folder, only) demonstrates how a PLL can be realized with
the USBLockIn and Labview. It consists of two parts. Part 1 starts with an initialization. Start the
VI after you connected everything and selected an output amplitude, the input gain as well as the
start and stop frequency and the number of steps to be taken. The VI now takes a spectrum with
the selected settings and shows the resulting amplitude and phase in the diagrams.
