I love the fact that my Ultra powers up using the exact same settings last active at the time I powered it off. ? ? This behavior is distinctly different from the original version I have, and different from what I expect based on the labeling of the preset zero titled ‘Load Startup’. ? ?

My Questions are:
- Is this the new behavior to expect? ? If so, shouldn’t the labelling of the preset zero button be changed to have the same behavior as the rest of the preset buttons?
- Is there a setting somewhere that I am missing that gives the user control over the power up configuration option (i.e. load either preset zero or load last settings used)?

Nice work Erik! ?And thank you so much for the larger screen, improved generator, and improved base frequency range. ? Keep it up.

My screen was the same out of alignment. It cut off the top left corner and info on the display, came from R & L. I carefully opened it up, unplugged the battery and carefully pried
up the display with a plastic car dash removal tool. Slipping under the display and PWB,? and working all the way around it so not to damage the display.
It is only held in place with some double sided tape.
Then realigned it with the markings on the PWB then put it back together.
All of the displays connections are by ribbon cable on one end only.
Case is held together by 4 small screws on the back. Be sure to reconnect the battery and don't over tighten the cover screws.

This is for info only and proceed at your own risk.

Thanks for reminding me. The picture used was from a pre production mockup. Will replace it with a picture from the real device

Hi,

mine also arrived today via GLS ordered on 11th of Nov. at Eleshop.

First test seems very promising, didn't tried ultra mode but the lower end up to 10MHz and the RBW and VBW settings that I missed badly on the TinySA.

The results are great! For me this little thing is really a game changer in the SA market!

It has even a better dynamic then my Metronix 2658 in the lower band.

The LNA is a very valuable add-on!

I will do some measurements with low distortion sources the next days and report back.

But I can say I am very impressed.

Thumbs up for your work!


All the Best,

Isidro

Erik,
? The main Wiki page shows the following image for the tinySA Ultra:



The input maximum RF level is labeled as +10dBm and maximum DC voltage as 10VDC.? On the delivered tinySA Ultra's, the input maximum RF level is labeled as +6dBm and maximum DC voltage as 5VDC.

Was there a particular reason the delivered units had their input RF and voltage levels derated?

Yes, please do

I ordered the Tinysa ultra at 19th November from Zeenko store, Aliexpress, China, and the instrument just arrived to my hands.

after turning it on, I quickly noticed that the screen is not well aligned in the case. it is almost impossible to read the entire last line at the bottom of the screen. I have attached this photo. Do I have to open and modify the alignment myself, without losing the guarantee? what are my options.

Apart from this anomaly, I congratulate you once again for this excellent product, Erik, I already have 2 first generation tinySA.

Should be ok

Hello everyone,
I calibrated my new tinySA after it successfully passed all self tests. After the calibration finished (without any indication of a problem), I fed the 30 Mhz calibration generator signal to the low input to check if everything is ok. The reading was -27.4 dB @ 30.2 Mhz, and I think that's a bit to low to pass as ok.
Is there anything I can do about this?
As to the question if my unit is genuine, I am not 100% sure. I made my purchase before becoming aware of the clone issue, and the place I bought it from? is not among the licensed vendors according to the wiki. On the other hand, the back plate checks out, but I guess it still could be fake.
I highly appreciate any suggestion how to proceed.

I wish all of you a nice day!
Matthias

Hi all,

just received mine. Ordered 10th Nov. at Eleshop, shipper GLS delayed one additional day - now screwing on SMA port savers :-)

Just wanted to provide a bit of a follow-up.? I received the new attenuator and did the same readings.

Thanks for the clarification!

Only a limited set of parameters (Attenuation, start/stop freq) is restored back to before shutdown, all others come from STORE AS STARTUP
But after startup you can do LOAD STARTUP to restore everything back to the saved startup configuration

The startup function itself doesn't work somehow, when TinySA is turned on it always sets the last state before shutdown and it doesn't matter what was saved STORE AS STARTUP.

Next I tested...
When I set the upper band and save it as STARTUP, when I turn it on, the STOP frequency is set to 800 MHz and the upper band behaves as off again.
The bad behavior is somehow related to using the STORE AS STARTUP function.
As long as I do not use the STORE AS STARTUP function after CLEARCONFIG, the behavior is OK.

Mirek

Will see if I can replicate this and find the cause.

Thank you for the very quick reply, Eric!

I did CLEAR CONFIG according to your advice and the behavior is as it should be, it is ok!

But it is OK only until I set the range from 1 to 100 MHz and save it as STORE AS STARTUP. After that, the behaviour is the same as before, i.e. bad.
So I must not set the lower band range as STARTUP.
Thanks for the help!

Mirek

Can you do a CONFIG/MORE/CLEAR CONFIG and do the tests again so see if anything changed?
