Thats the first one I tried. It runs like everything is fine, but come up with an error at the end. 11:55:59 : Error: failed to download Segment[0] 11:55:59 : Error: failed to download the File

Have you tried STCube?

Hello Eric, After some measures it looks very good: Firmware v1.1-88 RBW 10 kHz 33pF capacitors soldered Input LOW shorted USB cabel connected Just the local FM Radio station on 105.845 MHz is

Thank you Eric, now with RBW 10 kHz, no longer so good. 73, Rudi DL5FA

My test. Thank you for your work !! 73.

Hello, where is the topic? 33pF capacitors modification description? I want to try to improve the spurious.

No idea. Suggest you contact your supplier ------------------------------------------ For more info on the tinySA go to https://tinysa.org/wiki/

Well after 3 different computers, 5 different USB ports and 3 different USB cables, no luck.? Anything else to try? Rick W7RMS

Please notice the RBW I used in my screen grabs -- ------------------------------------------ For more info on the tinySA go to https://tinysa.org/wiki/

The cal output is hard coupled to the TCXO. The correction factor is used only for the low and high input frequency calculations ------------------------------------------ For more info on the tinySA

Erik, I measure my 30 MHz. cal output and it was 45 Hertz off.? So I measured the 10 MHz. cal output and it was 15 Hz. off.? I went to CONFIG/EXPERT CONFIG/MORE/CORRECT FREQUENCY and entered

Attached are 2 screenshots with firmware 86 and 88, no spurs. Installed 33pF capacitors some time ago. 73, Rudi DL5FA

Sandro, Be aware the problem is not an offset but a resolution issue. The output frequencies are on a fixed grid. So the maximum error will always stay the same. The TCXO itself is rather accurate.

Thanks for the selftes 6 output. All confirm what I was hoping for. No more needed ------------------------------------------ For more info on the tinySA go to https://tinysa.org/wiki/

Check if there is another device close by. Even a PC keyboard or mouse can cause problems -- ------------------------------------------ For more info on the tinySA go to https://tinysa.org/wiki/

Hello Bruce, thank you for your table. When all the data are in the minus side, adjusting the 10MHz one? step lower(is the resolution), it is possible to reduce the error upper 400 MHz? 100 Hz or

Spoors at 25.432M and 9.688M

Hello Erik, selftest 6 ch> 0:?? 96.678M 1:?? 96.705M 2:?? 96.705M 3:?? 96.678M 4:?? 96.705M 5:?? 92.608M 6:?? 96.705M 7:?? 96.678M 8:?? 93.743M 9:?? 94.159M 10:??

Hmm, i restore back to work after push CPU, look like bad soldering
