Re: Request for help: can you measure and report the MCU frequency?

 

I get 191.761 MHZ divided by 4 = 47.94.? This was an average of 3 measurements using the center of the 3db points.

Re: Reset?

 

You can always redo the touch cal by using the jog switch

Follow these steps:
  1. Reset the device
  2. Press the jog switch once (Main menu should be visible)
  3. Push the jog switch six times to the right(selected item should now be on Config)
  4. Press jog switch once (config menu should now be visible)
  5. Press the jog switch again (touch call should be activated)
  6. Touch upper left
  7. Touch lower right
This completes the touch calibration. The touch menu should work again.
Reset?

 

Having trouble with menu not functioning but I think it's because I screw up the the Touch Cal.? Is there a way to reset this device?
Re: Request for help: can you measure and report the MCU frequency?

 

Worst case MCU clock range reported till now 48MHz +/- 110kHz
If you measure outside this range please report.

Erik,

I get 191.91 (drifting +/-.02), -88.6dBm = 47.9775MHz-- 

Cheers

The MCU clock frequency can be measured using these settings.
Reset tinySA

The small signal somewhere below -90dBm is the 4th harmonic of the MCU clock.
Please post the frequency of this signal divided by 4.

If you do not see an MCU clock spur you can try the 2nd harmonic (96MHz) or 3rd harmonic (144MHz)

Re: Request for help: can you measure and report the MCU frequency?

 

The frequency varies a little bit, the span is about:

192.18 MHz, -88 dBm, /4 = 48.045 MHz
192.24 MHz, -88 dBm, /4 = 48.06 MHz

Re: Request for help: can you measure and report the MCU frequency?

 

I see the peak at 191.571MHz, so a MCU clock frequency of 47.89275MHz

Erik,
I get 192.159/4=48.03975MHz
or
144.117/3 = 48.0390MHz

Re: Delay due to damage

 

Hi Erik,

Apart from dexuan510 I have noted the following all selling the tinySA on Amazon UK.
Riiai_EU, Elikliv_EU, ytrew.
All have different trade numbers and VAT numbers apart from ytrew which does not show a VAT number.
There is a great similarity between each seller, with identical pictures of the tinySA, including one showing a PC screen background behind the tinySA which I do not recognise. It is nothing like my nanoVNA saver screen.
There are, of course, a number of sellers on EBAY.
All the Amazon sellers are listing a time delivery from ordering to arrival of about 12 days maximum. All the above are selling to the UK with prices shown in GBP.

Thanks Erik for all you have done in design and development of the tinySA

Regards from Phil G3SES

Re: Delay due to damage

 

Hello All,

I am trying not to bore you but I wish to send details of my order of a tinySA from dexuan510 via Amazon UK. One other forum member, as well as myself, had received?the same message, that the instrument had been returned due to damage.

After an extended tracking time period ended, I contacted Amazon UK to ask for a return of money spent (48 GBP total).
Less than 24 hours later the tinySA arrived safely and undamaged. It has the tinySA trademark on both the instrument and the case and all accessories are present
I have contacted Amazon to cancel my refund.

My conclusion is that dexuan510 is a genuine supplier to UK hams although amazon UK is not listed on Eriks list of recommended suppliers. The total time from order to arrival was 14 days.

Now to switch on the tinySA and join the happy band of tinySA users.

Keep safe
Phil G3SES??

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.
Cancel my order.
Agree to wait longer for a replacement.
I agreed to the latter but do not know the? delivery date as yet.

Let us hope this situation is unusual and packaging will be satisfactory in future.

Re: Local/PC display sync

 

Most settings on CPU sended by console, apply and update on display after send to tinySA
Re: Local/PC display sync

 

OK, interesting, many thanks. I did notice at one point that the screens appeared to be synchoronised after a change but it seems it was just a one-off!
Re: Local/PC display sync

 

There are basically two levels on which you can interface between PC and tinySA. High level where the intelligence is in the tinySA and you give "user level"? commands, or you use a low level interface which enables skipping overhead and thus allows faster scanning. Some PC SW communicates on high level, other on low level.
This low level communication may be confusing and I guess that is why Gabriel decided to disable the nanoVNA-V2 screen once connected to the PC.
I have no good solution yet,
Local/PC display sync

 

Just successfully updated to 99 and the new NanoVNA SW.

I may have missed something somewhere but is the display on the device intended to update along with the PC software display when you change parameters or not?

Using my VNA and the nanosaver SW I get correlation between both VNA and PC displays but not when using the SA in the same way (or at least not necessarily).

This is nothing to do with 99 because the "issue" has always been there from the beginning. It's not necessarily a big deal but just a bit confusing. Maybe I should have set something up?

Hi Erik

Will do if you send the firmware to kurt@...

Kind regards

I'm implementing user settable frequency for the AM and FM modulation but I have no means to measure the frequency of modulation.
Is there someone willing to receive a test firmware and measure the modulation frequency for AM and FM for at least two modulation frequencies?
