Configuring Frequency Modulation

To configure Frequency Modulation programmatically, use the IKtM9383.
Modulation.Analog.Frequency
configuration routine should typically perform the following functions:
27
var function1 = am.Sources.FunctionGenerators.get_Item(
"Function1" );
function1.Frequency = 1e6;
function1.Waveform = KtM9383AnalogModulationShapeSine;
var function2 = am.Sources.FunctionGenerators.get_Item(
"Function2" );
function2.Frequency = 10e6;
function2.Waveform = KtM9383AnalogModulationShapeSine;
var dualFunction = am.Sources.DualFunction;
var tone1 = dualFunction.Generators.get_Item(
"Function1" );
tone1.Frequency = 2e6;
tone1.Waveform = KtM9383AnalogModulationShapeRamp;
tone1.Ramp = KtM9383AnalogModulationRampNegative;
var tone2 = dualFunction.Generators.get_Item(
"Function2" );
tone1.Frequency = 6e6;
tone1.Waveform = KtM9383AnalogModulationShapeSine;
// Configure the paths
var amPath1 = am.AMPaths.get_Item(
amPath1.Mode = KtM9383AmplitudeModulationModeDeep;
amPath1.Type =
KtM9383AmplitudeModulationTypeExponential;
amPath1.Depth = 3;
amPath1.Source =
KtM9383AmplitudeModulationSourceFunction1;
var amPath2 = am.AMPaths.get_Item(
amPath2.Mode = KtM9383AmplitudeModulationModeDeep;
amPath2.Type =
KtM9383AmplitudeModulationTypeExponential;
amPath2.Depth = 3;
amPath2.Source =
KtM9383AmplitudeModulationSourceFunction2;
var amOut = am.LFOutput;
amOut.Amplitude = 1.0;
amOut.DCOffset = 0.25;
amOut.Source =
KtM9383AmplitudeModulationSourceDualFunction;
// Enable amplitude modulation on all paths
amPath1.Enable = true;
amPath2.Enable = true;
amOut.Enable = true;
