Re: #bug_report #bug_report

 

Did you use the latest FW?

#bug_report #bug_report

 

I noticed that if the parameter "leveloffset high output" is set positive (higher than zero), the behaviour of HIGH OUTPUT becomes dysfunctional: whatever the output level is set, the real output level increases automatically in steps up to +16 dBm.
In the video, in which I have used a 30 dB attenuator to avoid frying the tinySA receiver, you can see that when entering a high output leveloffstet higher than zero, the level rises in steps up to the top.?
This happens in my two tinySA (from Zeenko),?please test if this is the current behaviour. In this case I think it would be convenient to warn about until it is corrected.

Bob, Currently I'm not able to give an indication as other activities have higher priority

Erik,?

Thank you for conformation of the app not supporting high mode (because I just ran into that today).? Do you have an estimate of when you think the app may be updated (so I know when to check back for an update)???

AND thanks for such a great product!

Re: How we can use the CONFIG/EXPERT CONFIG/LEVEL CORRECTION/OUTPUT LEVEL?

 

When you activate the output level correction a 30MHz signal at -25dBm is generated and a keypad appears. You measure the level of this signal using another SA or a scope and enter the measured actual level

Many thanks. I knew it was probably me :)

Thanks Erik, but in this video we can see only that the input and output levels are the indicated, but no reference to CONFIG / EXPERT CONFIG / LEVEL CORRECTION / OUTPUT LEVEL. (?and how????CONFIG /??CONFIG /???/???and what this correction do, if it modify any parameter).

Merry Christmas,
Toni

Hi Erik,

Entering the actual level received in CONFIG / EXPERT CONFIG / LEVEL CORRECTION / INPUT LEVEL menu while being in LOW (or HIGH) input mode, this modifies the leveloffset low (or hihg) parameter so that the level shown by tinySA matches the actual level received.

??'?? and how????CONFIG /??CONFIG /???/?? and what this correction do.

Is there a video explaining it?
Thank you

Thank you Steve, but since I lost my arm and shoulder to cancer I will buy another one.? $60 US from RL Elect.

If I have to solder something, my wife has to hold the solder.

This TinySA is outstanding.? Erik is a genius.

Dave - I attempted to repair mine (you can buy the attenuator chips off of eBay).? The tools needed are a hot air rework station, solder paste, and a powerful magnifying glass.? Despite having all the tools needed and 40+ years as an electronics tech, I failed.? The attenuator chip is exceedingly tiny and the entire assembly fragile enough that the solder pads on the board couldn't survive the chip replacement.? These boards are built by robots.? If you have the tools it's certainly worth a try, though.? Worst outcome is a slightly bruised ego and you've got to proceed to buy a replacement.

Set your start freq to .5 MHz and stop at 5 MHz.

Re: Cal output 1MHz shows around 8MHz ?

 

That explains.The automatic peak finding has its limitations and in this case it did not find the maximum asit is too close to the zero Hz peak.
And measuring a signal at 1MHz with an RBW of 621kHz also does not make a lot of sense.
Set the maximum scan stop frequency anywhere between 2 and 20MHz and all will be well.

Hello Erik and good day.
Here are two images - I hope they are ok.. my phone is crap hihi :)

Re: Cal output 1MHz shows around 8MHz ?

 

I can't replicate this behavior. All is OK when I test.
Can you post a picture showing this?

Cal output 1MHz shows around 8MHz ?

 

Hi, quick test although I am probably missing a few brain cells :)?
Set cal output to 1mhz, then 'return to low in'? - IT shows around 8 Mhz - all other cal outputs seem to do as they say.
Any thoughts ?
