How to export the "Average Traces" from spectrum to script block?

Quote from mm_dev on 16/05/2022, 09:55

You can get the Average trace in the script block by adding a DSP processing block of type "Average" and connect it to the script blocks input, then the script block will convert "raw" spectra data fed into its input into a stream of averaged samples at its output:

(there are also other processing blocks like MinHold or MaxHold, see https://v6-forum.aaronia.de/forum/topic/rtsa-suite-pro-java-script-support/ for a list)

import { DSPStream } from "dspstream.js";

// function receives the result of the "Average" processing block and simply forwards it to the script block output

function onPacket(flags, meta, samples) {

let packet = meta;
packet.samples = samples();
DSPStream.sendPacket(0, packet);
}

async function init() {
DSPStream.addBlocks({avg: { type: "Average", config: { avgsamples: 10000, avgpower: true }}).then(() => {
return DSPStream.connectBlocks([{ source: "in0", drain: "avg" }, { source: "avg", drain: "script", input: "in0" }]);
}).then(() => {
DSPStream.receivePackets(0, onPacket);
});
}

function main() {
}

init().then(() => {
main();
});

And also you can see many Traces in Spectrum View , Max hold , Average and...

is it possible to do some arithmetic between them ? for example plot MAX HOLD + AVERAGE or something else ?

There is the "Binary Arithmetic" block for that.

Thank you for your reply

in the spectrum , Average trace has some good setting

When we use this trace with DSP processing  Block, then is it possible to do this setting ?

could  you please add this setting in your example code ?

Thanks

Changed the code sample to include "Average Samples" and "Average Power" config options. The other options are not available in the script block at this time.
