Just got a brandnew TinySA from the recommended dealer at Ali Express. I use it with VMA TinySA by Vitor.
When I press start, the spectrum display shows a full sweep. However the TinySA keeps on sweeping with the previously used manual settings.
The frequency entry on VMA shows:

Start: 0.1 MHz
Centre: 174950.1 MHz (??)
End: 349.9 MHz

the VMA is clearly live but it freezes after a few minutes.

Probably some trivial problem that I do not see or am no aware of.
Do I need to set the TinySA to USB operation?

Any comment/help is much appreciated.
thanks

Try a different USB port or cable?

Thanks for your quick reply.
Tried another USB socket on my Thinkpad laptop. No change. same problem.
Cable is original as supplied.

One more observation is that the VMA frequency axis labels are showing?

1Hz? ? 1Hz? ? 1Hz? ? 1Hz .........

even though the frequency settings are correct and the displayed active spectrum is also correct.

Try TinySA app. If that works contact Vitor.

Dieter, try english as? Windows language.

Hello,

Please e-mail me directly with problems regarding my software - this group should be use for the TinySA devices only, as per request from Eric, which I respect.

The mentioned problem results from having "," configured as the decimal symbol. Visual Studio is IMHO not coherent regarding the use of regional settings, some functions respect it, some don't. The fix consists in using "." as the decimal symbol.

I will try to fix this in future versions.

Regards,
Vitor

Also, the TinySA will stop his own sweep, when the raw command is sent through the USB/RS232 protocol. Once the raw command finishes its sweep, the TinySA resumes what it was doing. But since my software constantly sends raw commands, the TinySA ends up showing outdated sweeps, when it does not get time to do its own sweep. Also, the use of the raw command will not change the settings for TinySA's own sweep, so you end up seeing something completely weird.

Perhaps Eric could include a START/STOP command, so that external software could switch off the screen of the TinySA and stop it doing its own sweeps while being used remotely. The external software would then either reactivate the screen with START or the user would have to switch teh TinySA off and back on.

You can use the pause and resume command. When in pause mode a big green PAUSED text is shown in the status window

Thanks!

This problem was related to the regional decimal number formatting. The decimal number separator must be a dot and not a comma. Once I changed it, the frequency axis looked fine.

Thanks to Vitor for pointing me in the right direction.
