It goes away with Spur Removal in the Config menu.

I remember I saw the same signal when checking some 10 MHz standards using the tinySA (basic) It is very weak but still there. (nothing on the Ultra). This is from my V0.3 Not a problem. André

Where did you buy it?? Perhaps it is a clone..... Roger

I initialized it again and restored the initial value, showing -95dBm

Hello, I just checked my original TiySA like yours, not an ultra, and did not show any unknown signals like you posted. I would remove the case and check the two shields to make sure they are in place

I just checked my ULTRA. I enabled the preamp and set it to span from 5 through 15 MHz. I did not detect any spur at 10 MHz down to a reported -116 dBm. Dave - W?LEV @groups.io> wrote: --

Hi everyone, I have used my tinySA basic version for several years and it has passed the self-calibration. When I set the 10MHz test and connected nothing, it would appear in the spectrum. I have also

I got everything to work as I wanted! Thank you again Erik! Your help was very much appreciated :)

The impact of the RBW on a power measure is relevant when the RBW is small with respect to the bandwidth of the signal, since only a piece of the signal is taken in each measurement. The

The tinySA can do channel power measurements. You can use a channel wide enough to capture all the spectral components and it will give you the total power. -- Designer of the tinySA For more info go

It has to do with whether the IF bandwidth is sufficient to capture all of the spectral components, and also with the fact that the SA is calibrated to respond correctly to a CW signal, not power,

Thanks for this Don, so FM, nFM and AM will all have their power level impacted by a change to RBW, is there any formula for this ? Or is it a fairly minimal impact? Or it is more to do with the

That filter is the same I am using looking at our 6GHz STL, it works well. John

The power level of a *CW* signal should remain the same with RBW changes.? Modulated signals (which are noise-like) and noise signals (like the baseline noise level) will change with RBW changes. 73,

Thanks Guys, I’ve been using one of these: https://www.minicircuits.com/WebStore/dashboard.html?model=VHF-6010%2B It seems to be doing a good job at backing everything else off. Is there a better

Make sure you have a high pass or band pass filter in line when measuring with an antenna like this at those frequencies.I normally use Mini circuits high pass filters they are good enough to suppress

Need to look into this Yes > > > -- Designer of the tinySA For more info go to https://tinysa.org/wiki

Thanks to Erik and All devs for a wonderful device, also thanks to Ian for his great python work (the app) Just wondering about expected behavior of the 407 when working close to 7.3g, I'm doing some

G in AF formula is the Linear Gain of the antenna

I will first try with PCTEL OP451 omni wb antenna and will also take into consideration at least a log antenna. Already calculated all required info, specially AF (needed as input into TinySA -
