Re: TinySA Ultra screen misaligned
I received mine from R&L yesterday and immediately noticed the screen was mis-aligned with a tilt that cut off the upper left text.? What a relief it was to have this groups.io where I could learn that a) I was not the only one to have the issue and b) it is easily corrected.? And even better, after using the TinySA Ultra for a few minutes the display "fixed" itself, shifting into a straightened view.? I am assuming it must have just shifted a bit during shipping.
I already had the original TinySA, but this upgrade to the Ultra is worth every cent, and Erik deserves the equivalent of an academy award for bringing these powerful tools to the "radio table" for such a low cost.? I came very close to spending 20X the cost for an additional spectrum analyzer with a higher frequency range, had I not learned of the new Ultra version.

Re: TinySA ULTRA calibration reset error
Okay, Eric, I understand.
I'm gonna describe another little problem. Example:
I set the frequency to 50 to 100 MHz.
I click on the marker, the marker becomes active.
Then I execute: MARKER... MARKER OPS...CENTER
The action executes correctly, but after the action, a triangle
appears in front of SPAN on the bottom right of the display,
indicating that SPAN is active. However, Jog does not change the
value of SPAN where the triangle is, but changes the value of
CENTER.
But I think after the OPS CENTER action the marker should remain
active, Jog should still move the marker.

Should be ok now.
The generator and the SA use the same backup locations for
frequency and span so when switching between the modes the
frequency will always be reset.

Re: TinySA ULTRA calibration reset error
Hi, Erik,
I'm testing version 512 (TinySA reports it as 511). The bug with
the ultra band restoration seems to be fixed. Only when switching
mode to generator and back, the range is always set to 0 to 800
MHz in SA. Excellent work!

In the display driver you have to modify all occurrences of DISPLAY_ROTATION_* In the LCD configuration you have the switch the definition of LCD_WIDTH and LCD_HEIGHT In the touch_position function you have to switch x and y and then it's just a lot of work to make everything fit. ? --

I got mine today from R&L Electronics. This was a pleasant surprise as I had not gotten an email that it had shipped.

Mine just arrived form R&L Electronics. Ordered on 11/9/22. Now I just need to open it and play! It arrived just in time for our local amateur radio club meeting tomorrow (Saturday). It might make for a good show-and-tell.
Another thanks to all who brought this device to market!

Wouldn¡¯t it be a lot easier to just make a plastic or wooden clip to hold the whip at 90 degrees?

Is there a lot built on top of the assumption of horizontal orientation? I'm assuming I would then need to reorient touch input as well, possibly the jog switch. Would this still negatively impact display updates?
I'll admit I know very little about C or the limits of this hardware, but I've been looking for an excuse/project to learn. Currently browsing the source code downloaded from GitHub.

Re: TinySA ULTRA calibration reset error
Hi Erik, -Reading MirkD's description of his issue with the ULTRA, mine has exhibited the same behavior. Ran into issues requiring resetting of the Ultra Mode, even though it was checked, in order to set to a higher frequency than 800Mhz. I'll keep an eye on what you guys come up with regarding this.
Another issue I noted is in the interface of the Ultra with the latest TinySA -App, 1.1.20.1.I have updated the FW with the app with no issues whatever. However, if I use the instrument set up (four arrows on the left), the program loads the Tiny SA set up. If I import a frequency range from 0MHz (to whatever), the program will not display sweep. If I change the sweep range in the program, from .000001Hz (to whatever), the program sweeps normally. On the instrument, if I set a low frequency of .000001Hz (to whatever), the program imports this and sweeps normally.?Appears the program doesn't like the 0Hz (as the original setup on? the Ultra came from Zeenko).
I tried reloading the older FW in the instrument, no change, and tried an older version of the App, no change.
I tried my older Tiny SAs and found when I set the range to 0Hz (to whatever) the App uploaded the setup, but loaded the low frequency as .000001 Hz. The Ultra loads the low frequency as 0Hz. if set to that on the Ultra. Appears the low freq must be a frequency of at least 1Hz.?
Not a critical issue as long as the behavior is known.
By the way,as I work primarily in GHz range frequencies, using a 6GHz test generator, I find the instrument within 0.5dB of the generator output level and the frequency is very close as well. To get an accurate instrument at this price range that goes as high as 6GHz and that compares favorably with commercial instruments at 30X the cost, is a monumental achievement. Congrats to you and the team that developed this.? ----------------------------------------- From: "Erik Kaashoek" To: [email protected]Cc: Sent: Friday December 2 2022 6:11:03AM Subject: Re: [tinysa] TinySA ULTRA calibration reset error

Re: TinySA Ultra - Start Up Behavior
It does forget some advanced settings but that's no problem since one can save them in a preset.

TinySA Ultra - Start Up Behavior
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.

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

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