Python / "Jupyter Notebook" & "HTTP API" - MWE client example

This ipynb Jupyter Notebook shows a minimal working example, a way how I pull spectra data from the "HTTP Server" block for e.g. to use with numpy/scipy/matplotlib

Thanks for that very helpful post!

Is there a way to also get the timestamp for each single frequency measured?

If yes, how this can be achieved?

I hope I got your question right, but in the example you already receive the "startTime" and "endTime" along with the "sampleSize" element.


Well, that information might help and it might be possible to do some time calculations or estimates at which point of time an RF-measurement was performed.

I am coming from a measurement domain, where always RF measurements are performed at defined frequencies. Once a measurement is completed the next measurement frequency is selected. So it is possible to state a point of time when the measurement at a defined frequency was performed.

In the SA domain things appear different, because over a short time period a waveform of a received RF-signal is digitized and then transformed by FFT into the frequency domain providing amplitude- and phase values of numerous frequency points depending e.g. on the FFT resolution. Saying that, then it can only be stated that the amplitude- and phase values for a dedicated frequency where existing within the time frame where the signal was digitized?

Since we intend to measure with frequency bandwidths of less than 200 MHz the digitization time frame should be rather small.

Possibly the knowledge of this time frame would be accurate enough for our application to merge data by time stamps with an independent sensor during post processing.

Could you pls. state a typical time frame to be considered for a bandwidth of e.g. 160 or 200 MHz?

Sorry for being a bit "off-topic" for this post here.

Yes this is total off-topic. Please start a new thread and search the forum first e.g.
