schedule CSV save

Hello,

How can I make my SA44B to take a scan and save it as CSV from Skipe at a chosen time interval?

Thank you.

Best regards,

Cristian

Hello Cristian,

Currently the software does not have this kind of functionality. Out of curiosity, what type of time interval would you need and are you talking about each sweep being saved to a new CSV file? I would like to know more about your use case, so that if we ever decide to develop functionality like this, we can address your needs.

Hi Andrew,

Thank you for replaying to my post.
I want to save the spectrum at least one time per second (better 10 times per sec.). CSV has the advantage of being easy to use in different applications.

In my case I want to save automatically the sweep spectrum on a time scheduled and/or event triggered (like if the average amplitude will exceed a certain threshold).
For example, I want to record a 200MHz spectrum during one day to see what is an interference behavior like.

I’m not aware if I can do this with the recorder’s aid. And if it can do, how I get the recorded data in a general format in order to be analyzed with a different program (like Matlab)?

Thank you.

Hello Cristian,

Thank you for the information.

Currently the only recording the software offers, is a continuous sweep recording where the sweeps are continuously recorded to a single file, which is a binary file. That file can then be opened and viewed in the Spike software. In the preferences menu of the software, you can set a “Sweep Delay” which introduces a time delay between each sweep from the device. Using this delay and our recording feature, you could record a sweep every ‘n’ seconds. The file which is recorded is a binary file which only the Spike software knows how to read. You would not be able to open the file in Matlab. But the Spike software can view the file and allows you to scroll through all the sweeps that were recorded.

If you have any further questions, please let me know.

Hi Andrew,

This is a good news. At least I can visualize something.

Is there a chance to convert that binary or just to extract the spectrum from it (three dimensional table with time, frequency and amplitude) to a txt or other simple formats? Its not suppose to be that complicated if I know its structure, I guess.

Thank you.

Hi Cristian,

Right now we do not have any tools to convert the binary recording file to other formats. This is something we are looking into and may provide in the near future.

If it is useful for you, as you are examining the file in the Spike software, you can hit the export button on any trace to save the sweep as a CSV file. This only works for one sweep at a time, but will work on a live signal from the device as well as a recorded one.

Hi Andrew,

That is a good news I can export the recorded screens in CSV format.
I’ll try that.

Thank you.
