Re: updating the firmware using a bin file and dfu-util in Win10
That TinySaUltra ?document ?is excellent!
?Is there an updated ?version for the TinySa at the latest available FW (version 1.4-175)? ?What I currently have is dated March 2021.

Re: Max input signal at 10GHz.
John, simple rule.
Subtract the EXT GAIN value from the max rated input power and keep the tinySA measured power below that value
This works for both attenuators and amplifiers.
With ext gain of -30 dB your max rated power at the input of the external attenuator goes 30 dB up
With 20 dB external gain the max level at the input of the external amp goes 20 dB down

Re: Max input signal at 10GHz.
Thank you Eric,
?
This answers the question. I just wanted to make sure since it is an easy trap to fall into especially using pre amplifiers.? A reading of 0dbm after an amplifier offset of 20db is dangerous to the TinySA.
?
Something to keep in mind buying the amplifiers at Zeenco and using them in front of the ZinySA.

This is the latest Menu Tree Chart.? Hopefully it has all of the latest changes up to firmware v1.4.104.? Please let me know if it needs any changes. ?

Re: Continuously logging to CSV file using python
There is a simple python program here:
Note sure it that is what you are looking for.?
Its a good way to learn to use the serial port without getting into
the additional learning curve of Qt programming.?

I
would like to continuously log the frequency along with the
associated signal strength (in dBm) into a CSV file using
python, but I am unsure of the appropriate method to achieve
this. I have explored the USB interface for Wi-Fi, but there
are many different commands (like scan, scanraw), and I am not
sure which ones to use. Could you recommend some tutorials or
provide guidance on the commands needed to accomplish this
task?

Re: Cannot exit Mode menu
Problem solved. It was an OSI layer 8 problem (layer in front of the gadget/computer/...) .
Thought I could leave via touching an empty area but had to select "Spectrum Analyzer" instead.
?
Did a touch test just to make sure and it behaves similar to my nanoVNA.

Thanks and sorry for the spam

Re: Max input signal at 10GHz.
In other words:
"The TinySA Ultra +6dBm max input specification is not merely a suggestion, it's the law." :-))
There is some sort of inaccurate factory calibration up to 10 GHz. It was created using a constant power signal over the harmonic range. Most losses in harmonic mode are happening in the mixer.
Please do not exceed maximum input level, even at 10 GHz as you otherwise may kill the mixer, the input attenuator, the switches, or even the LNA due to leakage in the switches at 10 GHz

Max input signal at 10GHz.
Gents,
?
?With the input of the TinySA basically being an attenuator at 10GHz. and pre-amplifiers available for that frequency did anyone ever tried to find out what the maximum input signal at that frequency is?
?
As an example, lets assume a 30db gain amplifier, the offset to a known good signal? is ...say... -5 db? i.e the TinySA? with the current calibration reads 5db low. Then I can set the gain/loss offset to 25db? instead 30db and have a correct reading.? But, if I use a -10dbm? input signal, and the TinySA would read -10dbm, the actual signal at the input of the TinySA connector would be +20dbm.
?
Would that not exceed the input capability? Or do I miss something?
?

Re: Cannot exit Mode menu
Can you do a touch test to see how far off the touch calibration is?

Re: Reverse sweep direction?
No, I am connecting TX/RX from ESP32 UART 0 directly to RX/TX of the tinySA. Both are 3.3V.? On the RF side I could connect the tinySA directly? to the receiver input and have it tracking the receiver frequency. Then I won't have to worry about reversing sweep. But it goes only to 350 MHz and is slow when I change frequency. And yes, the code will be published.

Hi
It should be : STM device in DFU mode

You have to look? how to get the correct driver and change in windows.

Re: updating the firmware using a bin file and dfu-util in Win10
Hi Tom & josephlevy,
?
Thanks for pointing to the correct location of the file.? Apparently, the wiki's instruction to look for the file at is either wrong or outdated.
?
Subsequently, I copied the DFU_LOAD_BIN.bat file to the same folder as tinySA.bin. However, when I ran the program in Windows command prompt, it returned the below error message.?
?
Prior to running the aforementioned DFU_LOAD_BIN.bat, I think I have placed the tinySA into its DFU mode by powering up while pressing the jog switch. The tinySA screen is blank. Below was what Windows Device Manager reported when the tinySA was plugged into the USB port. Is the message "STM32 BOOTLOADER" an indication that Windows has detected a DFU device??
?

After upgrading to the latest version from v1.4-99 my tinySA Ultra will not let me exit the Mode menu. It has been small problem before as well. I had to touch the screen at the very, very right but now it just selects whatever is on the left.
I would have thought that touching the screen in any empty area will get me back.
The only way to get out of it is by flashing between v1.4-177 and my old firmware. Doing a Touch Cal didn't change things either.
?
Any help is appreciated

Re: Reverse sweep direction?
Very nice project. Please publish your ESP32 code when you have things working. ?I assume you are using a USB-C to TTL serial converter for interconnect?

Re: What to do when a selftest fails
Erik, I just got my SA Ultra from R&L and I think I damaged it. It fails self test 3. The carrier comes in 50dB low. In my excitement, I hit it with 35 dB of UHF for a few seconds and forgot to attenuate it.?
?
Is it cooked?
