Re: Delay due to damage

 

Hi Erik and Herb

This is a copy of what I received via Amazon UK.

I had held back from buying a tinySA until it was advertised on Amazon UK as I prefer buying items that way. Erik mentioned a few weeks ago that Amazon would be a source?for the?tinySA at the end of August. . The only Amazon seller was the one I used, that is dexuan. I followed the tracking which?said the tiny was in transit. The expected delivery date was Sept 18th to Sept 23rd, a very short?time. The attached information arrived today Sept 17th.?
The order was made on Sept 12th. and it?went?through Amazont smoothly.

I have decided to wait for a new tinySA and hope this arrives one day.

I just this is all genuine. What do you think?

Re: Serial over USB command list started

 

The wiki list is complete for now.

As you can see many commands are identical to those used in the nanoVNA.

Re: Delay due to damage

 

Philip,
I assume you did see the "where to buy" page on the wiki


and here you can see how the tinySA sold directly from Hugen are packaged


The seller Dexuan is unknown to me.


Delay due to damage

I ordered my first tinysa via?Amazon UK on Sept 12th.

The seller is Dexuan.

Today I received an email from Dexuan to say that the case was damaged and they have given me two options.

Serial over USB command list started

 

I started adding the serial over USB command list (console commands) to the wiki

Any feedback if this information is sufficient for someone that wants to use this?

Just send the content to me and I will add it.

Thanks for the info, Herb.

Will try the serial interface. ?

The display should not be a problem but you may have to solder some resistors to get the X/Y touch input in the right state (e.g. not touched)
Never has been tested

This can be implemented but you will also lose any change in setting you did after starting with the measurement so that is not perfect.?
The other alternative is to only do a limited deactivation of the measure setup. Which still may be difficult to understand.
How do other SA deal with this?

Come to think of it after completing automated measurements on a HP8568 I had to push the <instr preset> button to return to normal operations.? That is actually pretty much what you are doing now.? I also stored my settings in a register on the HP8568 prior to running an automated measurement so that I could recall them.

Probably the primary issue was lack of the 'back' button for exiting the measure menu.

in your first sentence about keeping it 10 dbm maximum ..is it minus 10 dbm or a normal 10 dbm which is 10 milli watts thanks

This is with 0dB internal attenuation. If you increase attenuation these numbers can go up with the attenuation but do not fry the internal attenuator.?
With 30dB attenuation the tinySA will survive a +30dBm signal for a couple of seconds.?
With attenuation on automatic you are perfectly safe and you can expect good measurements of you stay below +5dBm
But to give the attenuation some spare I suggest to always stay below 0dBm at the input. This will allow you to use the internal attenuation most effective


display delete?

 

I'm a bit too lazy to pull out the soldering iron, so I'll ask:? Will the SA firmware run correctly if it doesn't see the display and touch input?? I'm thinking about flying one under a hex-copter and every gram counts.

Thanks!

Hi Erik,

I thought that was the case, but I didn't want to suggest an 'unofficial' suppler to others who were interested in buying one, as the development team(s) would possibly suffer as a result.

Regards,

Martin


Re: Official or Unofficial sellers on Amazon ?

 

I have a few TinySAs from Maggie's Alibaba store that I can ship USPS Priority Mail. Contact me off-list if you are interested.

Re: New FW release: Added frequency grid indicator

 

Indeed!
I added too much measure menu options so the back key is no longer visible
Will be corrected in next FW

I have the frequency set to start 0 and stop 200Mhz.
If I select "measure" incorrectly, any of the available options will not allow me to return without disturbing the setup.
Even the "off" option returns the setup as default (0 - 350Mhz).

Erik,
? Igor is correct.? If you accidently select the measure menu there is no way to back out of it without losing your settings.? There should either be a 'back' button (intuitive) or selecting the 'OFF' button should act as a 'back' button (not as intuitive) that sends you up one menu level without loosing your settings.

? I usually store my current set-up in one of the four store locations before using the measure menu so that I can re-load it after a 'measure' operation, since I know exiting the 'measure' menu defaults to start-up settings.? Maybe as Igor suggested the behavior after exiting the 'measure' menu should be to return to the previous user set-up.

thanks for the reply i found on the main site that minus 30 dbm is reasonable is preferrably below ..but it does say for a short period of time 20 dbm will be ok useing the low band of the sa..once again thanks for the info nice little annalyzer for the price..

"with an external ittenuator what is the maximum input the spectrum annalyzer would handle 1dbm or 2 dbm or even lower any chance could u give me a accurate reading"

? ?Scott that's kind of a loaded question because it depends on the level of the signal you are measuring and the attenuator you are using.? See this page for maximum input ratings for both the LOW and HIGH inputs,??.? For best measurement accuracy Erik recommends that you choose an external attenuator that reduces your signal to -20dBm on the low port and -30dBm on the high port.? Use the LEVEL->EXTERNAL AMP setting to correct for the external attenuator.

"..also did u design this spectrum annalyzer?thanks for replying .."

? Erik is the proud designer of the tinySA and knows it backwards and forward.? He also maintains the firmware and the tinySA.exe software.? That is why he is able to respond so quickly to user input.? The tinySA is a result of almost a year of design work that originally started on the? Amatuer Radio Homebrew Test Equipment group.
