It seems there is some assumption about number formats making it crash immediately at startup. Setting my region to English/UK in the control panel before starting made it work for me. Probably a , vs . issue while reading settings.
That may well be the reason some other users are experiencing startup problems. I'll look into that.
Sasan wrote:Another very small issue:
I think the "Center Freq" field should not accept values "0" and "2000000000" (2GHZ) because then the start/end frequency would fall outside the frequency range of the device. (for example entering 2GHZ and having a sweep width of 10MHZ would set the End frequency to 2.005GHZ)
As mentioned in the release notes, sanity checking has not been fully carried out. This will be done in the next release.

I spotted that just after I sent Andy the final release. It's been fixed and will be in the next release. By the way, I have to thank you for your original post in https://www.sdrplay.com/community/viewt ... ?f=9&t=636
where you posted some sample code in C#. That got me started on writing a bit of code to control the RSP using C# - The analyser is the end product.

See the note above regarding number formats and English/UK settings. Could you let me know if this gets you running ?

Between runs I need to manually set up the bandwidth, etc. to match the first run, so things are all on the same scale etc. If that could be saved and recalled it would speed the process.
Saving the current anaylser settings is in progress and should be in included in the next release. The aim is to take a complete snapshot of all settings and allow them to be saved under a user-named setings file.
NK7Z wrote:. Perhaps a template for the naming the screenshots... Something like XXXX-Y, where XXXX can be user supplied, and Y is a date/time indicator in the form of DDMMYYHHMMSS.
To a limited extent this facility is already available, check the options box. You can provide a base name for the screen-shots. Each shot will have a number added to it. The number automatically increments with each shot taken. Both the screen-shot name and start number can be set. I like the idea of adding the date and time to the screen-shot name, that might be useful to have. I've added that to the ToDo list.
Paul wrote:I would like to understand how to make a trace visible on the waterfall (I haven't yet found the controls for this my fault?) - it's just a white screen.
I did change the spectrum trace colour from white to green with no effect.
Would it be possible in the future to link to a recording?
And would it also be possible in some future iteration to measure harmonics within a given signal/transmission?
The waterfall should work with the default brightness and contrast settings that are in place when the analyser is launched. Have you tried adjusting them to see it the waterfall becomes visible ? - Let me know if you still continue to have problems with this.
IQ recording and playback is already on the ToDo list.
The next release will include sweep widths above 10MHz, so harmonics should be visible then. If you mean something like modulation analysis then that is on the ToDo list but will be some way down the track yet. Could you give me a little more detail ?

K9AQ wrote:I paused the main trace to use the cross hairs to highlight the two tone frequencies and the 5th order IMD products. I found that the performance of the cross hair positioning is very poor when the display is paused, compared to how it operates when not paused. I hope there is something that you can do to improve that.
When the display is paused, the cursors should remain operational, but currently, they also pause. One to add to the bug list. In the meantime, you can use the Snap Trace facility to capture a trace on-screen and use that to take measurements from. You can hide the main trace while doing this if it's in the way.

Also a Zoom feature would be handy to spread the spectral display a bit in order to cut off the 'down slope' ends of the display.
The roll-off on the display is due to the way the current sweep system operates. Band-edge roll-off will be eliminated when the new sweep system is written. A zoom or display expansion feature will also be included.
Thank you all for taking the time to post your comments. Feedback like this is invaluable, be it a bug note, or a suggestion or request for some feature. It all helps. Please take the time to read the release notes. They can be found on the Windows Start Menu under Andrew Developments and address some of the issues mentioned here. Also, if you find any errors in the instruction manual, or anything does does not quiet make sense, please let me know.
