Hello Mirek,
Thank you for the feedback. I can comment on some of your points.
1. The “N points in M ms” display you are referring to shows the number of points in the sweep as well as the amount of time it took to acquire and plot the sweep. ‘M’ in this display is the sweep time.
2A. There is a sweep time control in the ‘Acquisition’ section of the sweep settings control panel. You can find this on the lower right of the application window (assuming you havent moved the control panels from their default position. Keep in mind, for a digital FFT analyzer we define sweep time as the total acquisition time for the sweep. It will not match the sweep time displayed on the graticule as that sweep time will include processing and display time in addition to acquisition time.
2B. See #1 above. ‘N’ in this display is the number of points.
3. You cannot control the number of points directly in our software. Only indirectly through the RBW and span settings. Sweep size is roughly going to be equal to 5*(span/RBW) for the flat top window. Other spectrum analyzers that allow you to control the sweep size are doing so by ‘binning’ adjacent frequency points. We do not do this, so when you go to export/record the sweep you still have the full resolution from the original sweep.
4A. This is a good suggestion but would require additional hardware development to perform and thus we won’t be able to offer this on our current spectrum analyzer line up.
4B. To load the default settings only, use the Presets->Load Default Settings control. This will retain your current measurment mode, but will go back to power on settings. To fully reset to power on state, set the analysis mode to Sweep and hit the “Load Default Settings” file menu selection.
5. This is a good suggestion and we have considered adding this functionality to Spike. We do not have a current time frame on this functionality, but it is something we are very much interested in. Most likely we will add this through a SCPI backend in the Spike software.
6. I agree this will be useful functionality when we add this. If you were not aware, we do have programming interfaces for our spectrum analyzers. They are in the form of C DLLs for Windows. Currently customers who need remote/programmatic control of our receivers use these DLLs to develop out thier needs. I realize this is not as convenience as an ethernet SCPI aware Spike application, but it is something we currently offer.
Thank you very much for your feedback. Let me know if you have additional questions or comments.
Regards,
Andrew
