Hi. Yes, it caught my eye right away. I enlarged the picture I took earlier.

Hi. Erik, thanks for the reply. For a few hours tinySA ULTRA was turned off and when I restarted it, this information appeared on the screen (Pictures attached to the letter). The only way to get

*if you have a look to the copper pattern of the ribbon cable you can see that it is not centered - you can also see that the size of the isolation area at the edges is different -? and also on the

Lithium Ion batteries have almost zero self discharge. So providing there is no current draw they should remain charged anlmost indefinitely. Having said that, it’s kinder to the battery to not

Hooray for the tinyVA battery.? I had not used my unit in over a year, turned it on, and the battery was at almost full charge.? To me, that is an outstanding shelf life from a quality rechargeable

Hi Dave, Lots of useful info there. Thanks. I will also write separately to you. -- Julian

Yes You have to switch the signal generator LOW OUTPUT to ON to get the correct output signal

Could it be alingment or some solid particle? I had issues like those with expensive connectors. [email protected]> wrote:

Hi. Erik, did you design the printed circuit board ? Before I started to disassemble the device, I decided to check if the signal generator was working. A picture of this menu is attached to the

1) For those who didn't bother to look at the diagram, it shows specifically 35 kHz. Enough said..... THE REST: I as well come from a physics background. Be extremely careful with those power

Indeed, the display test failed also. This indicates bad communication over the SPI bus. Can you open the case and try to reseat the LCD cable? Maybe that will solve the problem -- Designer of the

Thank you. Are the attenuators specific to your design of tinySA or are they are standard fitting device available from various outlets? One other point; what feature of a single loop (of 2mm tinned

It looks like the MCU can't read data through the SPI interface. if it still doesn't work after removing the SD card, the MUC's SPI port may be faulty. the SD card, LCD, and RF chip are all mounted on

When you are probing with a loop antenna you can start at large distance (two meters) and reduce the distance if there are no strong signals. Unless you are exiting the coil with a LOT of power, then

The tinySA Basic (0.3.1 model) will actually work well down to 10 kHz but you lose some dynamic range -- Designer of the tinySA For more info go to https://tinysa.org/wiki

What about the issue of potentially damaging the SA? How can I work out the dB of the fields surrounding the coils to best protect it? I do have one of those cheap field meters for elec and mag

Yes, an important question. 10kHz - 20MHz I think is reasonable. I know the tinySA is not accurate below 100kHz but I have heard that by making some Config adjustments then it will detect
