Re: My internal 602540 LiPo battery not holding a charge.

 

There is no limit on mAh, the max charging current is limited so a large mAh battery will load slow.

My internal 602540 LiPo battery not holding a charge.

 

What is the max mAh battery @3.7v rate can I mount outside of case to get user time without damaging the TinySA?


Re: Just a thought¡­

 

For all the wishful asking for enhancements: Put your money where your mouth is!? Would you pay ~ $250 ~ $300 for all your wishes and more with a 4" display and a decent waterproof case????? Would you wait a year for the free development of this, or pay upfront to help with the costs?? ?
This would still be a tremendous value, so put up or shut up!
And to many more asking for assistance, read a book about radio technology!!? Many excellent free ones available, though some might want to ask for a particular type font to suit their whims.? If you had a support contract with Siglent or Rigol, not to mention HP-Agilent-Keysight you would be paying more for each month than the cost of the TinySA and have way slower and lousier support!

Erik, many thanks for your efforts, updates and patience with some people.? As you can tell, my patience has been worn thin.


Just a thought¡­

Erik has given us a jewel of a product, with a boatload of features, at a ridiculously low price. But with continual requests for more capability, I wonder if it will ever be finished. Bug fixes are one thing, but expecting him to add free enhancements until he runs out of ROM space doesn¡¯t seem fair. That said, it would be nice if it could¡­

Re: Ability to save High and Low output mode configuration and automatically recall it on power up #feature_request

 

The idea would be to have the possibility to save it as STARTUP (or as STORE 1, 2, 3 or 4), using the same memory location used to store the set of parameters that are currently?stored in each of these presets.?

Re: Ability to save High and Low output mode configuration and automatically recall it on power up #feature_request

 

I agree with this idea.
I've missed this a few times. mainly the external attenuator that I always use fixed and I always have to reconfigure.


Re: TinySA Signal Generator accurate enough to check sensitive FM receivers?

 

¿ªÔÆÌåÓý

Not certain which generator is being referred to here. We seem to have drifted off the TinySa onto another unit.

The FM modulation mentioned in previous comment, is that the modulation frequency or the frequency deviation? I haven't found the deviation level adjustment for the TinySA yet. I see the Tiny SA as primarily a spectrum analyser with a generator thrown in as an extra. The original question about using the TinySA to check "sensitive" FM receivers has become lost.

It has FM modulation - OFF,1,2,3 KHz.? It also has selectable DTMF code. Basic functions but does them well.
There are some downloadable 'instructions' but they seem to apply to a much much earlier version of the firmware and are nonsense.

Ability to save High and Low output mode configuration and automatically recall it on power up #feature_request

 

Hi,

I don't think this is possible at the moment, but I may be wrong, in which case can someone tell me how to do it ?

I have an application where I'd like to be able to set-up an output sweep configuration and store it in the TinySA, and then have the ability to automatically recall it on power up and for the output to be enabled.

The idea is that the TinySA could then be used as a stand-alone signal source or sweep generator, without having to set it up from scratch each time it is turned on.?

Regards,

Martin

White Screen : hard or soft bug #tinysa

 

Hello
I receive my tinsa; I use it : no problems ; After? many trials i upgrade the software ; ok it works. I use my tiny Sa and some times we are blocked on white screen. I need to turn it on and off many times to recover screen.? I make again solders around the LCD? flex : no improvements. i suspect some hardware issue : when I press some part of PCB , it works agains...After many solders I destroy the? flex contacts. Thus? I buy a new LCD screen ,and? i solder it again.? It works, buu issue is still there. Thus I connect usb for serial monitoring.: When LCD is white, ?C is still reponding to ''help'' command''.? If I send a simple ''reset'' , screen is ok again.
I suspect some solder issue..but not around the flex. I don't see nothing. If somebody could help. Many thanks.??Version : tinySA_v1.3-338-g42ce69a

Re: New FW release: Special fast scanning mode for noise sources

 


A quick try with a BG7TBL no(i)se source, a 50 dB att and a RTL-SDR FM band stopfilter.
Which looks very much like the specs and what the NanoVNA measures.



A typo Speedup misses an S.


Re: TinySA Signal Generator accurate enough to check sensitive FM receivers?

 

Hi Dale.

Yes!
The TinySA has? a sweep function!

Go to 'mode' select 'low output' and then 'sweep'

Very nice adjustable sweep!

Locked Re: #bug_report #bug_report

 

Exactly. It not only in the Measurement menu but also the Signal Generator Frequency setting.
(I also checked the NanoVNA which doesn't have this bug.)

Found this playing with a gpsdo from the HBTE group.


Re: New FW release: Special fast scanning mode for noise sources

Thanks Erik,

New version installed but will delay testing until tomorrow.

Geoff.

New FW release
Version V1.3345

Changes:?
- Removed wrong line under big number display
- Added special fast scanning mode for noise sources

The noise source scanning mode can be activated with DISPLAY/SWEEP ACCURACY/NOISE SOURCE and it reduces a full low input scan from 415ms to 118ms
This mode should only be used in combination with a noise source as used for measurement of filters or attenuators as in this mode scanning is done like in a VNA and it is possible small bandwidth sources are not seen.
Reducing the number of display points will further reduce the scanning time. Full range 101 points are scanned in 42ms. Great for tuning a filter.

Joe,

Does that RF Generator have a sweep function?

The guy seems very unfamiliar with both his SA and also the gen itself. But there is some interesting info.
One thing to note is the the signals he is seeing on 300MHz from the gen simply do not exist, they are somewhere in his lab.
Here is the gen at 300Mhz on the tinySA full band and notice there is NO 200/whatever spur.? He also doesn't seem aware of the modulation settings of dtc settings. but -- somewhat informative anyway here is the little gen to the tinySA at 300MHz. No issues. The noise floor of the tinySA is much higher here as we would expect.
