Hi, I am trying out my friend's tinySA. I'm hoping to replace my RF Explorer if I can get this issue resolved. One thing I cannot figure out is how to get the traces off the SD card just by connecting the tinySA to my Mac via the USB C cable. Any advice on an easy way to do this? This is a dealbreaker for me because I really don't want to fumble around with micro SD cards while I'm working on site.

Hi, with the various options visible in the vertical bar on the left of the image below and after recalling a previously saved preset, in my TinySA Ultra with firmware v1.4-196 there is a problem with the spacing of the text of the various onscreen options that causes the date to go under the green icon representing the Sd card, as visible in this screenshot: This results in the date and time not being readable and, sometimes, when trying to press the green icon representing the Sd card, the screen for changing the date appears instead of saving the current image visible on the screen. The problem sometimes does not occur as visible in the picture below: I report this here in the hope that the problem can perhaps be resolved with the next firmware update. Bye

Be sure to check the cleanliness of your ultimate 1152 MHz LO. Remember LO noise will also degrade receive performance in direct proportion to the amplitude of the noise pedestal. In addition, the width of the multiplied noise pedestal will be multiplied by the SQRT of the multiplication factor, in this cast: by 3.5. -50 dBc is pretty noisey for a quiet LO. I set my signal generator to 1152 MHz and took pictures with both the HP8568 and the TINY SA with identical measurement parameters (you can read those from the images). See the attached images. Interesting (especially for Eric) that they both show about -70 dBc to the noise pedestal. I'm impressed with the TINY SA performance in this respect! Virus-free.www.avg.com-- Dave - W?LEV

I have created a Python Qt5 application to work with the TinySA Ultra that runs in Linux. https://github.com/g4ixt/QtTinySA Working Features: LNA on/off SPUR auto/off Theoretically unlimited points, but I have set the maximum to 15,400 for no particular reason. RBW control 4 different colour traces, all can be turned on/off and set to average, max hold or min hold Selectable averaging Amateur band frequency selection Start/stop frequency selection 4 markers. Each trace has 1 marker associated with it. Markers can be set to normal, delta, or one of the four largest peaks. The selected marker(s) can be set to sweep start frequency with a button, or can be draggged to any desired frequency. All standard pyqtgraph features, which are selectable by right-click on the graph display, including: Export as CSV, HDF5, Image file of various types, Matplotlib window, SVG 3D spectrum (very primitive) with measurements over time represented as a surface plot. Can be clicked/zoomed/dragged/rotated using the mouse.

The tinySA Ultra is level calibrated up to 6GHz but it will, with reduced dynamic range, go up to possibly above 10GHz. So I have this challenge for all tinySA Ultra users: Can you demonstrate a real application (not just a signal generator) where you use the tinySA Ultra above 5 GHz? As a first step I welcome a measurement of the 5GHz WiFi band in max hold with some channels active Maybe a ham can try to observe the 5.7 or 10GHz band? Anything else? -- For more info on the tinySA go to https://tinysa.org/wiki/

The NRSC (National Radio System Committee) in the US landscape, has published a study examining the effects of RF noise on AM radio reception in cars. See there : https://www.radioworld.com/news-and-business/nrsc-releases-details-of-am-band-rf-noise-study What is interesting is the fact that a TinySA is one part of the measurement system, as depicted below. It highlights once again that Erik's tools have also a place of choice in a professionnal field, congratulations ! The complete study report is also available there : https://www.nrscstandards.org/reports/nrsc-r102.pdf 73 - Jean-Roger

Extra QEX copy
4
Does anyone want a copy of the January/February 2025 issue of QEX? The ARRL sent me two copies. It has the tinySA tracking generator design article in it. Of so *respond to me privately* at kc0wjn at gmail dot com Responses to the list will be ignored. The magazine is free; shipping cost from 32754 USA to be paid to me by PayPal F&F (the shipping cost using USPS Media Mail is probably trivial). DaveD KC0WJN

Issues with TinySA USB Connection in C#
24
Hi, I'm writing a C# program to receive data from TinySA and analyze it. I need to retrieve data from these three commands every second: frequencies data 1 data 2 The issue is that, from time to time, TinySA does not return data over USB. After this happens, it stops responding to any commands I send over USB. I suspect this might be because I need to set the correct parameters during the connection process with TinySA over USB. Unfortunately, I couldn’t find the required parameters in the documentation to properly connect to TinySA using USB. Could you please let me know the correct way to establish a USB connection with TinySA? I've tried several methods, and the following setup has been the most stable so far: PortName = "COM3"; BaudRate = 115200; new SerialPortStream(portName, baudRate) { Parity = Parity.None, StopBits = StopBits.One, DataBits = 8, WriteTimeout = 500, ReadTimeout = 5000, Handshake = Handshake.DtrRts }; await serialPortStream.WriteAsync(commandBytes, 0, commandBytes.Length); Thanks in advance!

TinySA Ultra becomes unresponsive when touching the screen or using the toggle button to bring up the menu
Whilst using the TinySA Ultra to take signal measurements yesterday, the device became unresponsive. I have power cycled the device and we have updated the firmware, with no improvement. The device starts and launches the FFT screen with the attenuation and frequency marker which can be moved with the toggle. However, the amplitude is not shown on the grid. If the toggle is pressed, the menu opens and the device becomes unresponsive. If the screen is touched, the device becomes unresponsive. Has anyone had any experience with this?

I just did a firmware update same way I have done it many times in the past. Powered the SA Ultra off and back on and screen flashed several times and now the touch screen is not working, cannot get a menu and no scan trace on the screen, Just the grid and all the information/items showing on the left side of the display. Any suggestions would be appreciated, did a search for this issue but did not see a solution. Already removed the back and disconnected the battery and did a factory reset with the jog wheel and power on button.

How to get a quick EMV approval with tinySA Ultra?
29
Hello. I bought my tinySA ULTRA in 2023 to do self-certifications of developed hardware and/or to find out if my hardware will meet requirements for approval. Though, I did not have any success yet. The ULTRA is calibrated and tested, but I have no idea on how to use it for this purpose in best way. Is a video tutorial available, showing the usual way/process of doing that? I am working to 100% on Linux (have a Linux workstation running openSUSE 15.5 x64). It would be great if a program is available, generating a report with needed details by controlling the tinySA ULTRA over USB and finally generating a printable report for archiving. It would be great if somebody can help. Thanks in advance!

Spectrum Analyzer / RF 101 and consultants
5
I apologize in advance if this is a dumb question but I need guidance. I have a Tinysa spectrum analyzer but I am completely new to radio frequencies and the spectrum world but NEED to learn as soon as possible. All the book search results I have found so far seem advanced because I am not even familiar with the terminology. Can anyone tell me where to start? I am not a techie. Any beginner’s resource for dummies will help. Also, are there people/consultants out there who you can pay to advise you on how to set your spectrum analyzer based on what you are trying to capture and who will interpret the results for you? If so, what are they called (so I can search the web), and/or where can I find a reputableone? Thank you very much.

I have an Elecraft XG3 signal source that I use for troubleshooting radios. It outputs a square wave full of harmonics that can be set for -107dBm,-73dBm, or -33dBm. I have attached some screenshots from my Oscilliscope and the tinySA. When I was using the tinySA with the windows app the app measurement did not agree with what I see on the screen. So basically none of my readings agree. The scope measurements kind of bother me because they are pretty far off. This is not a lab quality scope (Hantek DS02D15) but I did not think it would be this far off. Just wanting some input on how to resolve these differences. thanks.

Hi, I am am since a year a radio amateur, and i am learing moren and more but also finding interference issues here and i want to find them and if possible eliminate them. For this i ordered the TinySA as tool. I am suffering of a disturbance signal over the 2m and 70 cm band, it seems it is extreem strong and has a lot of harmonics toe. The idea is to make analyses during lets say an hour and find out of the interference is time driven or nog, and how wide this interferance is over the bands. On my SDR i can only see a part of it. Attached some of the sreenshots i made, and if someone recognise it, please tell me what it could be, it is day and night... An approach, or point out documents and or youtube recordings that could help me are welcome. in the filename is de date and time, it seems the issue is every 10 minutes but i am not 100% sure, this is also something i would like to learn if i could make a recording of the spectrum and that way find the spikes in time. Thanks for your suggestions Eelco de PD1EG

I don't want to force a standard 3.5mm 3 conductor jack all the way into my TinySA Ultra and take a change of breaking it. Has anyone tried using a two conductor jack and, if so, did it make the channel connections despite not being fully seated? Thanks,

TinySA Ultra Interval trigger still not working
2
Hi Erik, Back in 2023 I reported that the Interval trigger feature you implemented for me on the TinySA was not working properly on the TinySA Ultra. Today I upgraded the firmware on my TinySA Ultra to tinySA4_v1.4-196-g1e9c187.bin and I tested the Interval trigger feature again and it's still not working properly. My test is to feed in a 60 or 120 Hz square wave (which is rich in harmonics) into the TinySA Ultra, set the TinySA Ultra to Zero Span mode with a frequency of 1.8 MHz, set the display sweep time to 20 msec, select interval trigger with a time of 16.66 msec and I should see spikes that are stationary (very little movement left or right) but I do not get stationary spikes on the TinySA Ultra whereas I do on the TinySA when doing this same test. Sure would be nice to get this feature working properly on the TinySA Ultra as the TinySA Ultra has the built in LNA as well as expanded frequency coverage. I'm sure your buried with the new TinySA Ultra Plus (congrats) but please put this on your to do list if possible. Thanks, Don (wd8dsb)

A feature request: Zooming with two fingers

My Android smart phone has that feature. You can zoom/enlarge the screen image by spreading two fingers on the screen. Is this possible with TinySA in the future?
