Hello all, I ordered a NanoVNA but amazon sent me a SAUltra on accident (which I planned on ordering too anyways) But it fails the self test and the calibration too. I fed in the 30MHz cal signal and it reads way low. My old SA reads the cal signal fine. When I connect an antenna, the FM broadcast band is faint to say the least. Any tips?

Looking for beta testers for a new product
2
For a new product I'm looking for a number of testers, preferably in Europe The product is tiny and has a high resolution dual time stamping and frequency/phase measurement capability Frequency/time/phase reference can be external or internal using a built in gpsdo. The accuracy is less then the tinyPFA but it has much more functionality No specific test equipment availability is required but it's important to have a project that can benefit from the above functionality to ensure actual usage. If you are motivated to join the testing and do have sufficient time to frequently load, test and report on firmware updates, please send me a private reply with some info on your project and how you intend to use the product. If available, you can add some info on your experience and relevant test equipment Replies to the list will be ignored. -- Designer of the tinySA For more info go to https://tinysa.org/wiki

Good day All. I'm trying to restore/align an old FRG7 Com-radio, have a TinySA that have been using as an RF sig gen and a Zeewiie DSO1151g scope that 'should' run past 100Mhz, well lets just say 30Mhz is about its limit, this means I'm unable to look at signals in RF range. My question, attached are sample alignment procedures for the RFG-7. Given that I dont have a fit-for-purpose scope (have three scope probes) but do have a TinySA and a NanoVNA (on the way) how should I then perform the alignements that require use of a scope, so what modifications do I make to testing and how should I review the results. Scopes, Im happy with using. SA and VNA interpretation, I'm not familiar with and no option to buy a higher bandwidth scope. Thank you. Br John.

tinySA App #Feature Request
#Feature
tinySA App does not display the RBW or attenuation when they are set to AUTO; perhaps they could be displayed on the status bar along the bottom. I also do not see a control nor display for VBW. Having all 3 displayed on screen shots would be valuable for documentation purposes, VBW control/display would be more "nice to have" as most leave it untouched. Thanks and best regards, Don Brant

How to stop or abort an ongoing scan or scanraw command?
3
Hello there, I am using the Tiny SA Ultra+ (ZS-406, firmware 1.4-196) and sending scan and scanraw commands to retrieve spectrum data, however I was wondering Is there any way to stop or abort an ongoing scan or scanraw command before it completes? From my tests, it seems that once the command is sent, the device continues the process until completion. But in certain cases, I would like to interrupt the scan early (e.g., if the user cancels the operation in my application). Thanks in advance! Juan, M0WWA

Thanks for DFU-Buddy Software
2
Thanks to chri5k for adding DFU-Buddy to the files section. I wasted about 20 minutes trying to get my windows machine to recognize my TinySA. Windows wouldn't even recognize the SA or let me install the DFuse drivers. Then I remembered seeing DFU-Buddy I had seen when I was browsing the files section. I grabbed my Mac and installed the software (you do have to go into system settings and give permission to install the software) and the rest was easy. Opened the software, found my TinySA, selected the dfu file I had downloaded and installed the firmware. Done and dusted in way less time than I had fought with the PC. Terry

Battery of my Tinysa Ultra expired & no new available ! Does "smart" power bank is compatible ?
7
Hello. I have Tinysa Ultra (1st hardware version), & using it as panadaptor to my ICOM7100 ...... It's built-in lithium battery is expired & I searched in my country, Iraq, for new original replacement but I couldn't find ! I found original power bank of smart type that has "smart" charging controller & support multiple types of voltage output (5V, 9V, 12V, 15V, 20V, 5 - 11V) with maximum power output of 85W. The "smart" power bank "automatically" determine needed voltage for the device .... I asked about it & one of my friends (YI6AT) asked me to never using it to power my Tinysa Ultra or my antenna analyzer because it can destroy such devices ! Due to my failure to find original replacement for battery of my TinySA Ultra & because the "smart" power bank is original & of high quality I prefer to ask about it's safety to be used with my TinySA Ultra. So, please help me about this. Data about power bank: - CUKTECH Power Bank - 20000mAh 85W Specifications (from it's paper user manual): - Model: PB200 - Battery Type: Lithium-ion cell - Battery Energy (Rated/Typical): 72Wh/73.44Wh 14.4V 5000mAh/5100mAh - Rated Capacity: 11000mAh (5V DC 3A) - Input Port: Type-C - Output Port: USB-A/Type-C - Input: IN1(Type-C1) 5V DC 3A, 9V DC 3A, 21V DC 3A, 15V DC 3A, 20V DC 3.25A - Output: 85W MAX (The maximum output peak power is 85W (OUT1 20V DC 3.25A OUT2 9V DC 2.22A), subject to the actual testing method adopted by CUKTECH lab. * OUT1 (Type-C1) 5V DC 3A, 9V DC 3A, 12V DC 3A, 15V DC 3A, 20V DC 3.25A, 5 - 11V DC 6.1A 67W MAX * OUT2 (Type-C2) 5V DC 3A, 9V DC 3A, 5 - 11V DC 3A 33W MAX * OUT3 (USB-A1) 5V DC 3A, 9V DC 3A, 5 - 11V DC 3A 33W MAX * Multi-Port: 5V DC 3A (OUT1 5V DC 1A OUT2 5V DC 1A OUT3 5V DC 1A) 9V DC 6A (OUT1 9V DC 3A OUT2 9V DC 3A) 12V DC 3A 15V DC 3A 20V DC 3.25A www.cuktech.com https://cuktech.com/collections/frontpage/products/cuktech-15se-power-bank-20000mah-85w-max Can I use this power bank to power my TinySA Ultra while I'm using it connected to my ICOM7100 ?? (we added IF output port for this station: YI1ZQ made such customization for his STN & for my STN) Any help is appreciated !

Any chance to have a analog output representing RSSI level in Zero span mode? And/or level at cursor point on analog output. Like a RF-detector, just much better since Rx bandwidth can be set and much high sensitivty than typical diode-RF-detectors.

There is a problem with this firmware. вт, 11 февр. 2025 г., 20:11 Erik Kaashoek via groups.io <erik@...>:

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
