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 -

If you are interested in knowing the field strength at your location, you only need to consider the equipment at your end. It makes no difference how the field happened to get there. If you are

So, I asked ChatGPT and gave me this answer: Is "shortcut formula" good enough for my use-case?

Thank you. I think I found the line in the code to edit. Thanks again.

The source of the tinySA is on github. You can change this value in the code and build a new FW -- Designer of the tinySA For more info go to https://tinysa.org/wiki

The selftest shows that U22 needs to be replaced, no problem But I see D4 at the RF input. Is this a real diode? There is no recognizable marking on the part. Because if so this tests blown also. What

Thank you all for recommending affordable log periodic antennas! The PCTEL OP451 ( 450 MHz – 6 GHz, vertical polarization) I found is around $90 (used, not new). Is it worth that price tag? As I

Hi Erik, I have tried to all options that I know of to get the TinySA Ultra ZS405 to auto save traces as fast as possible. The best I can get is every 30 seconds. There seems to be a hard cutoff in
