With the wrong previous exe some wrong settings got into the configuration file that is automatically loaded. Can you try? to load this configuration file? The output from the log should be like like this where the important difference is "v 0 O 433800000" (in bold)
>>attenuate 0
>>p 6 0
>>v 1
>>o 443800000

Can you check if the settings page looks like this  and if not, change to these values? In the picture you posted it shows "Level/dB" as 7.8 but that should be 2 And attenuation should be 0 If it still does not work, can you enable the log and post the log?

Erik, I updated the new firmware and PC software, but it still doesn't work.

Re: Measurement examples posted on wiki
Hi Hans,
Thanks, excellent investigation.
The SI5351 SW used was optimized for fast sweep for my DIY VNA so it is terrible with spurs.
|
Sorry guys, must have been a bit confused yesterday.
Please use a new executable found here
?
and for those that already have the v0.2 HW, do update the FW of the tinySA with the file found in the the same location (either ch.bin of ch.elf)

Re: Measurement examples posted on wiki
Hi Erik
The Si5351A is prone to crosstalk between outputs, if the outputs are heavily loaded (e.g. 50-ohm loads). There's only a single supply pin into the chip. Other suffix versions of the Si5351 in larger packages have separate?buffers with their own supply pins and this is less of a problem.?
Therefore if you want to use multiple?Si5351A outputs on different frequencies, and you don't want that level of crosstalk, you need to buffer them with a relatively higher input impedance buffer.?
Additionally phase noise performance is degraded when the outputs are heavily loaded. One partial remedy to this is to use a DC blocking capacitor, which appears to restore the phase?noise performance.?
Note?also that the output spectra of the Si5351A will depend somewhat on the internal configuration. For best low jitter performance (i.e. good phase noise performance) the datasheet?recommends even integer MultiSynth divider stage configuration where possible, using fractional feedback division on the PLL stage. There is quite a lot of bad Si5351A code out there in libraries and such, that does things the WRONG way.?
My article on phase noise measurements of the Si5351A might be of interest see?

Re: RFI Source Identification Signature Storage Application
Tom,
For now there is no analog output foreseen.
Display demodulated AM in volt (Vrms of the carrier) is being worked on so effectively it will behave like a digital scope.
Now all I have to add is the ability to store traces in flash which may be useful anyway.
For the todo list

Re: RFI Source Identification Signature Storage Application
? ? ? ? An analog AM bandwidth of 1KHz would be sufficient for tracking down utility power noise sources which typically generate 100 or 120 Hz fundamentals along with a few harmonics. The amplitude significant harmonics typically fall below 1 KHz. A real time, linear analog amplitude response output for connection of an external scope may be the most practical way to support hydro related RFI source searching. Maybe a filtered PWM output active during zero scan mode might be worth considering. The pocket size scopes which I discovered advertised online have significant trace storage and PC USB interface features. Some interesting models are priced within the $50-$100 range, IMHO not too bad of a financial burden for those serious about using the tinySA for tracking down RFI sources.

My mistake,
Release version uploaded.
Can you test if this runs?
When the selector bock pop's up you can select "mockup" and the SW will run with a simulated source
