Re: New Tinysa-am having troubles
A digital camera would work, if you have one, otherwise hold the tinysa
up to the camera embedded in your computer and take a picture with
whatever software is provided with your computer, on Linux that would
be Cheese for example.

I suggest you start here and do the self-test and then post the results. Roger

Renee,
? Does your unit pass the self-tests?? If so, you should be able to pick up the FM band using the telescopic antenna connected to the LOW input port.? Posting the results of the self-test should help Erik in troubleshooting your tinySA.

Re: New Tinysa-am having troubles
Actually, although I am technical, I dont understand what? self-tests are in relation to the tinysa. BTW tnx fer writing? back¡.. Renee ?

Re: What to do when a selftest fails
Okay. Thanks Dave! Yes, I've read that attenuator-test procedure. Will try that if I see that "fail" error again; hopefully I'll never see it again!

If it happens again try doing the attenuator test. It's in the wiki on how to do it.

? ? For comparison with measurement data from an EMC receiver making logarithmic sweeps, your suggestion would not work for Alois as the measurement increments are different between linear and logarithmic sweeps and the measurement data points will differ. ? ?In addition to logarithmic sweeping, an EMC receiver/software is capable of a lot more measurement points than the tinySA; so, a 10kHz to 30MHz sweep may need to be broken up into several frequency bands and "stitched" together when using the tinySA in order to match the measurement data from an EMC receiver. ? ?If care is taken to closely match measurement bandwidth, frequency increment, and protect the tinySA front end from 50/60Hz related harmonics/transients when connected to a Line Impedance Stabilization Network (LISN), then I agree with Alois that tinySA can be an economical measurement receiver for performing pre-compliance conducted emissions measurements.

Hello Erik,
Thank you. I hope, this would come in the future, and I assume
it's not so difficult, as only the LO has to be programmed with
log. values. The tinySA combined with a LISN helps to do easy and cheap EMC
precompliance measurements at 150 kHz ... 30 MHz. The level
results are comparable with those from EMC labs, but the EMC
receivers are sweeping logarithmic. So, comparison would be
perfect with log. sweep.
BR,
Alois

Re: What to do when a selftest fails
Hello Erik, first-off, thank you for a nice and affordable product, sir!
?
Just wanted to share my experience, and test result(s):
?
Purchased from Zenko store on Ali-Express. Ordered 4th October 2021. Delivered yesterday (10 Nov).
Came with FW of 5th May 21 (1.3-111).?
1) Initial self-test failed on the 12th.
2) Did a power reset, and tried again. It passed all tests.
3) I upgraded the FW to 1.3-320 (8-Nov-2021)
4) Passes all tests
?
Attachments: Serial number label and failure-mode.
?
I hope I don't see that "FAIL" again. :-)
?
73,
Prem

tinySA logarithmic sweep?
Hi,
Is there a way to switch to a logarithmic sweep, like other spectrum analyzers do?

Re: New FW release: Add '+' sign when output above 0dBm
Erik, updated the firmware, a minor note: The DFU file is named: tinySA_v1.3-321-g5fea965.dfu, but the displayed version on the tinySA is: tinySA_v1.3-320-g3b6d29f
Thanks for all your work!

New FW release: Add '+' sign when output above 0dBm
New FW release Version 1.3320 Changes: - Added a '+' sign to the indicated output level in high output mode when the level is above 0dBm. A small cosmetic change to warn users about the possibly high output levels when in high output mode.
