How to generate a lot of waveforms using for loop?

clear()

if(!('Wavegen' in this) || !('Scope' in this)) throw "Please open a Scope and a Wavegen instrument";



if (Tool.question("Frequency should be constant?") == true) {

frequencyconst = Tool.getInteger("Frequency constant value is", 0, 0, 10000)

print("Frequnecy is constant and the value is " + frequencyconst )

} else {

frequencyfrom= Tool.getInteger("Frequency range from [Hz]", 0, 0, 100)

frequencyto = Tool.getInteger("Frequency range to [Hz]", 0, 0, 100)

frequencystep= Tool.getInteger("Frequency number of steps", 0, 0, 100)

print("Frequnecy range is from: " + frequencyfrom + " Hz to " + frequencyto + " Hz and the step is " + frequencystep)}



if (Tool.question("Generator voltage should be constant?") == true) {

voltageconst = Tool.getInteger("Generator voltage constant value is", 0, 0, 10000)

print("Generator voltage is constant and the value is " + voltageconst )

} else {

voltagefrom= Tool.getInteger("Generator voltage range from [mV]", 0, 0, 100)

voltageto = Tool.getInteger("Generator voltage range to [mV]", 0, 0, 100)

voltagestep= Tool.getInteger("Generator voltage number of steps", 0, 0, 100)

print("Generator voltage range is from: " + voltagefrom + " mV to " + voltageto + " mV and the step is " + voltagestep)}



Wavegen.Channel1.Mode.text = "Simple";

Wavegen.Channel1.Simple.Frequency.value = frequencyconst;

Wavegen.Channel1.Simple.Amplitude.value = voltageconst;

Wavegen.run();

Scope.run();

 

 

Hello! This is my code to generate sinusoidal waveform. But it works only for constant frequency and voltage.

I need help with for loop or something to generate this waveform but for example after choosing:

Frequnecy range is from: 0 Hz to 10 Hz and the step is 5 

Generator voltage range is from: 5 mV to 10 mV and the step is 2

 

0,2,6,8,10 Hz with 5 mV  and 0,2,6,8,10 Hz with 10 mV. So i want to generate 10 waveforms with an interval of for example 5 sec.

Hi @Monika997

var rgAmp = [0.005, 0.01]
var rgFreq = [0,2,6,8,10]

rgAmp.forEach(function(amp){
    Wavegen.Channel1.Simple.Amplitude.value = amp // amplitude voltage is half of Vpk2pk
    Wavegen.Channel1.checked = true // enable, output offset or initial value
    
    rgFreq.forEach(function(freq){
        if(freq==0){
            Wavegen.Channel1.stop()
        }else{
            Wavegen.Channel1.Simple.Frequency.value = freq
            Wavegen.Channel1.run()
        }

        wait(0.1) // you may want to wait a bit for the external test/circuit latency, like 100ms
        Scope.single()
        if(!Scope.wait()) throw "stopped"
    })
})
Wavegen.Channel1.stop()

Thank you so much @attila

I've got one more question. 

These values are already given in the code - var rgAmp = [0.005, 0.01] var rgFreq = [0,2,6,8,10] but in my program I enter the range and the number of steps in the popup window.  I would like the two-dimensional array to be made up of these values entered in the window.

 

 

if (Tool.question("Frequency should be constant?") == true) {

frequencyconst = Tool.getInteger("Frequency constant value is", 0, 0, 10000)

} else {

frequencyfrom= Tool.getInteger("Frequency range from [Hz]", 0, 0, 100)

frequencyto = Tool.getInteger("Frequency range to [Hz]", 0, 0, 100)

frequencystep= Tool.getInteger("Frequency number of steps", 0, 0, 100)

Hi @Monika997

You can use something like this:

function conf(amp, freq){
    Wavegen.Channel1.Simple.Amplitude.value = amp
    if(freq==0){
        Wavegen.Channel1.stop()
    }else{
        Wavegen.Channel1.Simple.Frequency.value = freq
        Wavegen.Channel1.run()
    }

    wait(0.1) // you may want to wait a bit for the external test/circuit latency, like 100ms
    Scope.single()
    if(!Scope.wait()) throw "stopped"
}


if (Tool.question("Frequency should be constant?") == true) {
    frequencyconst = Tool.getInteger("Frequency constant value is", 0, 0, 10000)
    conf(0.005, frequencyconst)
} else {
    frequencyfrom= Tool.getInteger("Frequency range from [Hz]", 0, 0, 100)
    frequencyto = Tool.getInteger("Frequency range to [Hz]", 0, 0, 100)
    frequencystep= Tool.getInteger("Frequency number of steps", 0, 0, 100)

    for(var i = 0; i < frequencystep; i++){
        conf(0.005, frequencyfrom + (frequencyto - frequencyfrom)*i/frequencystep)
    } 
}

}


if (Tool.question("Frequency should be constant?") == true) {
    frequencyconst = Tool.getInteger("Frequency constant value is", 0, 0, 10000)
    conf(0.005, frequencyconst)
} else {
    frequencyfrom= Tool.getInteger("Frequency range from [Hz]", 0, 0, 100)
    frequencyto = Tool.getInteger("Frequency range to [Hz]", 0, 0, 100)
    frequencystep= Tool.getInteger("Frequency number of steps", 0, 0, 100)

    for(var i = 0; i < frequencystep; i++){
        conf(0.005, frequencyfrom + (frequencyto - frequencyfrom)*i/frequencystep)
    } 
}

 

 

 

 

So now my code look like this:
 

clear()
if(!('Wavegen' in this) || !('Scope' in this)) throw "Please open a Scope and a Wavegen instrument";



function conf(amp, freq){
    Wavegen.Channel1.Simple.Amplitude.value = amp
    if(freq==0){
        Wavegen.Channel1.stop()
    }else{
        Wavegen.Channel1.Simple.Frequency.value = freq
        Wavegen.Channel1.run()
    }

    wait(0.1) //100ms
    Scope.single()
    if(!Scope.wait()) throw "stopped"
}







if (Tool.question("Frequency should be constant?") == true) {
    frequencyconst = Tool.getInteger("Frequency constant value is", 0, 0, 10000)
    conf(0.005, frequencyconst)
} else {
    frequencyfrom= Tool.getInteger("Frequency range from [Hz]", 0, 0, 100)
    frequencyto = Tool.getInteger("Frequency range to [Hz]", 0, 0, 100)
    frequencystep= Tool.getInteger("Frequency number of steps", 0, 0, 100)

    for(var i = 0; i < frequencystep; i++){
        conf(0.005, frequencyfrom + (frequencyto - frequencyfrom)*i/frequencystep)
    } 
}




if (Tool.question("Generator voltage should be constant?") == true) {
    voltageconst = Tool.getInteger("Generator voltageconstant value is", 0, 0, 10000)
    conf(0.005, voltageconst)
} else {
    voltagefrom= Tool.getInteger("Generator voltagerange from [mV]", 0, 0, 100)
    voltageto = Tool.getInteger("Generator voltage range to [mV]", 0, 0, 100)
    voltagestep= Tool.getInteger("Generator voltage number of steps", 0, 0, 100)

    for(var i = 0; i < voltagestep; i++){
        conf(0.005, voltagefrom + (voltageto - voltagefrom)*i/voltagestep)
    } 
}



Wavegen.Channel1.Mode.text = "Simple";
Wavegen.Channel1.Simple.Frequency.value = frequencyconst;
Wavegen.Channel1.Simple.Amplitude.value = voltageconst;
Wavegen.run();
Scope.run(); 

Here is my problem: For example, by entering a fixed frequency value, it changes without any problem. However, wanting to change the constant voltage value, it is not the amplitude that changes, but also the frequency.

Hi @Monika997

If you look carefully your code, each conf function call configures amplitude and frequency, and performs a Scope capture.
Then at the end or your code you are setting frequency/voltageconst and starting Wavegen and Scope.
The *const variables may are not even be initialized if in your questions not constant is selected.

 Unfortunately, I don't really understand how to fix it.
