1.1-85 Fails on Self test 11

 

Hi,?
I have two Tinysa, one which arrived today and updated both to the latest firmware 1.1-85.
One completes the Self Test fine, whilst the new one (older on the serial number though) hangs at test 11. Its doesnt "fail", it just stops and needs a power reset.
Any ideas?
Cheers
David
 

Can you check if the waterfall works?

No it doesn't work.
But its fine on the other one.
 

Sorry, just to update as well, the waterfall also locks it up.
Thanks
David
 

Thats is consistent.
There seems to be an error in the interface to the display and unfortunately the display test (test 11) hangs instead of giving an error message.
If you are very brave you can try to lift the display and resolder the 18 wire flat cable. Otherwise your tinySA will function well, without waterfall.
Using the serial over USB you can give the command
selftest 0 12
to execute the last of the selftests and check the attenuator
or you can connect high and low connectors, enable the cal output at 30MHz, set center = 30MHz and span =5MHz and do MEASURE/MORE/LINEAR and see if you get an (almost) flat green line.

"If you are very brave you can try to lift the display and resolder the 18 wire flat cable."

Done! All good now, thanks. There was one very clearly not soldered, and a couple that 'might have been a little shy of solder. But the self test ran without issues and the waterfall is perfect!.
Thanks for all your help, it was awesome!
Kindest regards
David
PS, being able to use the second TinySA to calibrate the HIGH worked a treat. I've done it to both and that gives me everything I need. Thanks again.
