Scripts

[tomas61]

I am trying to run scripts, but I haven't been able to find a good complete set of instructions/reference manual
Got the ECMA-262 manual and waveform 2015 ref. man. documents but neither tell me how to make a while loop that will stop when I press a key.

Also, why the data is not getting updated

for(outLoops=0;outLoops<10;outLoops++)

{

 

// reading 50 times, 5 seconds plus

for(loops=0;loops<10;loops++)

{

 

// acquire data

Scope1.single();

Scope1.wait();

 

data = Scope1.Channel2.data;

for(index=0;index<8;index++)

{

thresholdLow -= 0.01;

thresholdHigh = thresholdLow - 0.01;

data.forEach(function(sample){if((sample < thresholdLow)&&(sample > thresholdHigh))counter[index]++;});// build histogram

} //index

 

 

 

} // loops

Hi @tomas61

You can use the wait() function or instrument.wait() or dialog like Tool.question() .getNumber() ...
See the examples or the Help tab in the application.

while(var i = 0; i < 10 && wait(1.5); i++) { ....

if(Scope.wait()) throw "Stopped"

if(!Tool.question("Continue?")) throw "Abort"

Thanks Attila,

But most importantly, why the variable data is not getting updated

 

It only works with the first set of data 

for(outLoops=0;outLoops<10;outLoops++)

{

// reading 50 times, 5 seconds plus

for(loops=0;loops<10;loops++)

{// acquire data

Scope1.single();

Scope1.wait();

data = Scope1.Channel2.data;

for(index=0;index<8;index++)

{

thresholdLow -= 0.01;

thresholdHigh = thresholdLow - 0.01;

data.forEach(function(sample){if((sample < thresholdLow)&&(sample > thresholdHigh))counter[index]++;});// build histogram

} //index

} // loops

Hi @tomas61

The data should be the data from the last capture.

You are performing 10x10 captures and the thresholdLow is decremented for each capture by 8x0.01 The threshold value for last capture will be 7.92 lower than for the first capture. You may want to initialize it for each capture.

[tomas61]

Yep,

you were right, the bins weren't getting filled because my threshold was too big

Where do you get the info for commands like "Tool,question..."

Is there a main language reference book/document

Thanks

Hi @tomas61

See the Help tab of the application, like in the earlier screenshot, or select Browse in the Help menu.

Thanks

One more, can you send an example on how to plot data from the script, keep getting parse error when trying "plot1.Y2.data[] = lData;"

if(!('Scope1' in this)) throw "Please open a Scope instrument";

Scope1.single();

if(!Scope1.wait()) throw "Stopped";

var average = 0;

var lData = Scope1.Channel1.data;

plot1.Y2.data[] = lData;

lData.forEach(function(sample){average += sample;})

average /= data.length;

print("Average: "+average+" V");

Hi @tomas61

Use ".data =" not ".data[]"

if(!('plot1' in this)) setPlots(1)
...
var lData = Scope1.Channel1.data
plot1.Y2.data = lData
...

Hi Attila,

 

Why the  "

var data = Scope1.Channel2.data;

if(!Scope1.wait()) throw "Stopped";

plot1.Y1.data = data;" is different than the data displayed in the scope

 

how do I plot a bidimensional array

 

Thanks

[attila]

Hi @tomas61

Use .visibledata
Use X.data and Y1.data

[tomas61]

How do I use the plot1.Y1 to display an array

var peakBar = [];

plot2.Y1.peakBar;

also can I plot two or more data sets  in a single plot window

Hi @tomas61

Thanks

how do I format a number to display only two decimal points in print

print(totalCounter);

will print this

2.2000000000000006

What is the base language you use for script, (java, python, etc)

This would be so much easier with a good user manual

Hi @tomas61

See the Help tab, press F1 or Browse under Help menu.

1. To round a number to 2 decimals you can use: round(value*100)/100
2. To format the number for text conversion use: value.toFixed(2)

[tomas61]

How do I define bi dimensional arrays?

var peakCounter = [];

var peakCounter = [][]; ---syntax error

 

var peakCounter = [,];---doesn't give me a syntax error but it doesn't work, it only follows the index after the comma

Thanks

Any way to send data to google sheets?

Hi @tomas61

You could use start or exec functions to call an external application to perform the task.

Hi @attila

What is equivalent to "Ctrl+Space" combination key if I use Waveforms in a Mac laptop? Thk ! 

[attila]

Hi @3D_loves_eng

Ctrl+Shift+Space
