Episode 1325 New $120 spectrum analyzer 4" screen 100kHz to 800MHz frequency range and up to 6GHz in ULTRA mode 200Hz min. resolution bandwidth Specifications: tinysa.org/wik... Buy: tinysa.org/wik... Be a Patron: / imsaiguy
I’ve owned the original TinySA for a while, and in that time I’ve found it invaluable from a hobbyists point of view. I’ve preordered the Ultra primarily for its increased frequency range. I use a lot of 5GHz devices and to monitor them I’ve relied on my HackRF1 and a PC, this Ultra will permit a much simpler work flow, especially when out in remote locations.

Thank you for the information one month before Christmas. To try out my spectrum analyzer I bought cheap microwave motion detectors in the range of 5.8GHz, 10.525GHz and 24GHz which serve a simple sources and receivers. The motion detectors can be tuned (slightly) by the supply voltage and one of the the 24GHz modules even has an internal divider to measure the frequency with normal instruments at 3MHz. Together with LNBs receiving at 10GHz and using harmonics to reach their input range one can play around in the frequency range with tubes, resonators and shields. (Of course with limited power.)

@BigEars2011 @rickeaston3228 Gheesh people. The man spends his own money on equipment and his time on setting up and presenting this material without asking us for a dime and you have the gall to criticize him for not creating a professional quality presentation. If you want "Reality" TV slickness then break out your wallet and send the man some cash so he can hire script writers, directors, camera operators and such. Personally I prefer this unscripted first look over a professional presentation as the real part of reality comes through unfettered.

It appears they mandated people go to the website to get a 'password' in order to force them to read about what the limitations were of the Ultra mode before they enable it. The designer clearly understood that there are many KZitemrs who don't know what they're doing who would buy one of these, never read about how to use it and what its limitations were in Ultra mode, then do a video badmouthing the units because of the trade-offs that have been made in order to create a $120 SA that displays frequencies in the multi-GHz range. I think the designer was very wise for doing that, and I'm quite pleased with my Ultra that arrived yesterday. The only thing that bothers me is that it has so many features I have to learn how to use. :) BTW, the rudimentary PC software they have available to run with it has multiple sample-averaging you can use to help kill noise. Of course, that slows things down, but for $2, who cares?
@IMSAIGuy

Noise floor comparison is not fair because: The reference instrument had a 10dB attenuator inserted, the smaller instrument had no attenuator. The reference instrument had a faster sweep than the smaller one. Do do a comparison, the attenuator and the sweep settings must be the same. BTW, even if it cannot compare to a real spectrum analyzer, this is still a very good instrument.

He reads 100. kHz as 10. kHz. If he continues to use that pencil eraser to operate the "tiny ultra" the abrasives in the rubber will wind up scratching that plastic screen into foggyness. That is why the manufacturer included that guitar pick in the tool bag. I don't understand why he didn't compare some FM radio station's signals and what the jumping modulation does to the displays. 88-108 MHz. Ron W4BIN

I've seen the latest 2.8 screen versions listed as "Upgraded Version: ESD Protection Diodes" the frontend load ratings are lettered on the front as +10 dBm 10 VDC Max. I see listings for the Ultra (4'' Screen) that state the higher load ratings on the front. I know one US Seller had the higher rating front end image posted on their store site but have changed it back to the image of an Ultra with +6 dBm 5 VDC Max. " Would you know anything about this? or is there any hearsay circling about upgraded ESD protected Ultra units looming in the future?

Something like PCB antennas and RF routing for WiFi / BLE is what on my mind.

The noise floor comparison showed about 15dB difference. This should have been expected as the RBW of the HP was at 3MHz and the RBW of the TinySA Ultra was 850kHz. That's a difference of about 4 to 1, so there should have been about 6dB or so difference between the two. Not sure where the other 9dB came from.
