Erik,
? I'm not sure what serial console in the FW you are referring to.? There is a serial console function in tinySA-App for sending console commands, but on the PC side space should not be an issue.

Using the .dfu file the command line is even shorter
dfu-util -a 0 -D tinySA.dfu

For updating using linux there is a program call dfu-util

It also runs under windows, this is my commandline
c:\work\DFU\dfu-util? -a 0 -s 0x08000000:leave -D c:\work\VNA\tinySA\build\tinySA.bin
under linux this should be something similar

remember: you can NOT brick a nanoVNA or tinySA. If the update goes wrong, worst case you have to open the housing and connect two contact while powering on and you always can try again

Hi,

I have a nanoVNA H4 and now 2 of the tinySA. I have been reluctant to install any of the "upgrades". I can now afford to risk one of the tinySA units to try installing the "new, improved, giant economy size" software. I am not using PC software for these yet and may decide to not use it. I will not have Windows in my home - actually my computer. So updates to exe files have no appeal unless they will run under WINE.

I will go to the files and WIKIs to get a handle on what to do.

New FW release
Version v1.1-9

Changes:
- Disabled serial console due to insufficient space
- Added THD measurement so MEASUREMENT/MORE menu

The THD measurement gives the % TDH of the signal that is under the first marker by summing the power of all harmonics of the signal under the first marker in the current scan
The maximum number of harmonics you can take into account is about 30 so with a full span in low mode you can measure the THD of the cal output at 15MHz and 30MHZ but not 10MHz or lower.
For lower frequencies reduce the span till the THD measurement appears.

Can someone check if the measured number is about correct?

Hi Erik

Now it works as designed!

Thank you very much.
Every new version makes the combo TinySA and the App. more useful.

That is the simplest answer. RF will go where it wants to go. What you have there is a very unbalanced antenna system. A USB isolator may help.

Oh, you are using the telescopic antenna at the input and then you connect a USB cable.
The USB cable is acting as part of the antenna and is picking up a huge amount of noise.

The same thing happens when you have a signal generator and a tinySA and both are connected to the computer with USB and the cable between the generator and the tinySA is not the lowest resistance between the two devices (because of bad cable or bad contact)

Hi Erik,

I regret to say that the localization problem still exist. I'm using comma as decimal separator in the Windows regional configuration and the program throws this error: "Range check errors" when trying to leave the program (it is due to live.csv file writing attempt). The same happens when trying to save any CSV file. The problem is also in v 1.0.240.3 where is was tried to fix.

I found another remaining text from the cousin program:? The Marker info shows S11 instead of tLevel when in Log Power(dBm). It is shown ok when in Lin Power (Watt).

Best regards,

Ignacio EB4APL

Release tinySA-App 1.0.240.4

Erik,
? The 'External Amp' setting is working on my installation.? In the screen capture below I have a 6dB attenuator attached between the 30MHz CAL out and the low port.? With -6dB entered in the tinySA-App 'External Amp' box, the tinySA 'Amp' status display is shown as -6.0dB and both tinySA and tinySA-App show a corrected value of -24.6dBm at 30MHz.

? ?

?The 'External Amp' value isn't transferred automatically from the tinySA to tinySA-App in the opposite direction, but the measured levels match, which is the important thing.

The 'Full Range' button seems to be mislabeled as it doesn't really change the tinySA-App sweep settings to the full range - unless the tinySA is set to the full range.

Make sure you install v1.1-7

New FW released
Version v1.1-7
Changes:
- Serial port integrated
- Offset console command added to support External Amp setting from tinySA-App

BTW it works fine if I do it on the TiniSA screen!

Hi
1.1-5 ge0ab998

And I see in the .ini file 'offset' according to the number I type in the box, but no change of scale ...
I'll try to re-flash the FW
TIA?? Joe.

Which FW du you run

Hi Erik
So for me it does not... (other things appear to work fine!)
Will wait for the next versions...

Thanks for all the great work on the HW and SW ( you and OneofEleven)

Hi Erik
Getting better and better...
Somehow I don't get the "external amplifier" gain to change the displayed gain ....(I just type in a number like 25 and 'enter', no units?...)

TIA Joe.
