tinySA-App uses scanraw thus ensuring no gaps and 50% overlap. This displayed step size is for information only -- For more info on the tinySA go to https://tinysa.org/wiki/

I have also noted that AM depth cannot be set beyond 50% without the screen showing a "depth error" message.

Well, counterfeiting Cisco routers is more profitable than doing it with TinySA's? given the market size involved. In other way, the case of the guy selling them to U.S. DoD shows how stupid these

I have received my Ultra a few days ago and was just looking at the Signal Generator function. It seems not possible to set the modulation frequency greater than 1KHz on FM (OK on AM). Whatever I try,

I don't know. But I have a guess: These people are moonlighters who, in their day jobs, they do similar jobs that are bigger, harder, and more even more evil.

Erik, Is that also true when using tinySA-App? I notice step-size is calculated in the app status panel based on frequency span and number of points selected. Herb

I can’t fathom how anyone can produce clones of something so soon after the release of a product like this. Case tooling, pcb layout, parts acquisition, reverse engineering the firmware, testing,

This is always guaranteed in the tinySA If you choose a any amount of measurement points and span the tinySA will insert hidden measurement points to ensure step size <= RBW/2 if needed. -- For more

Bob, For final compliance testing using the specified CISPR-16 RBW is mandatory but for pre-compliance testing, when using a spectrum analyzer versus an EMC receiver, you can get away with a 10k or

All stores with "tool" in their name have been either selling clones or buy and resell at a profit. Please only buy the tinySA Ultra from listed stores. -- For more info on the tinySA go to

Hey, What do you think about these following sellers ? Are they safe places ? https://www.aliexpress.com/item/1005004970582571.html??? (Geek Selected Tools Store)

Bob, The RBW is implemented by the chip manufacturer in embedded DSP code that can not be modified and there? is only a limited set of parameters you can modify to steer this code. I will have a look

Hello Eric, The CISPR 16 RBW requirements are quite specific. Since RBW is implemented in software, it would be relatively easy to implement on the the TinySA and/or the ULTRA. You and Hugen a

Hello John and Herb, We really should have started a new thread for this TG discussion... But have I missed something here? I am not sure of the TinySA ULTRA architecture, but my understanding is that

If you are getting 90dB or more isolation with your design, you might want to share the details and see if Erik can produce a tracking generator accessory for the tiny SA/tinySA ultra. Herb

Not really, if you use the low level output and amplify it with low noise MMIC you have recovered your signal and have plenty of reverse isolation to have full dynamic range.If you set the LO output

The LO output (977 MHz??) is directly available at the CAL output at a much higher level by selecting CONFIG->MORE->LO OUTPUT.? The leakage you observed limits the dynamic range of tracking generator

Mike, Think of the tinySA Ultra as two separate pieces of test equipment depending on the selected mode. AM/FM are found in the signal generator mode after selecting MOD (modulation). In the spectrum

Thanks Herb, now I just need to navigate my way back to that screen where I found the 'AM, FM etc.' in the first place. Mike C. Sand Mtn GA
