Multi band and Measurements
The first measurement that will support multi band functionality is IMD (as it was the simplest)
Signal generator was set to generate 2nd harmonic at -30dBc and 3rd up to 5th harmonic at -40dBc This is what you get without using the multi band option The measurement range of the harmonics is limited by the noise floor You can improve the dynamic range by manually setting the RBW to 1kHz but the scan time will be 800 seconds Using multi band IMD measurement you only?enter the frequency of the fundamental (11MHz) and the span to be used when viewing the fundamental/harmonics (20kHz) and you get this in 2 seconds with an automatic RBW of 1kHz More to come. -- For more info on the tinySA go to https://tinysa.org/wiki/ |

Re: TinySA Ultra Menu-Tree Chart pdf file in landscape mode
I greatly appreciate Kurt's continuing work on this document I started at the beginning of this year.? I've been distracted for the last several weeks with some other projects (a new "toy" called a radiosonde) and our daughter's wedding coming up in a couple months.
Adobe Acrobat can rotate the pages to either landscape (which is how Kurt and I work with the document in Microsoft Visio) or portrait but I didn't realize the Acrobat Reader (not the full version) was unable to rotate the pages. I'm glad I bought the TinySA Ultra last December. I had no idea at the time I bought it that I'd be using it to look at the 1.68GHz signal from a 49 year old radiosonde transmitter I found on surplusshed.com!? It only lasted about two minutes before an old paper capacitor apparently shorted out and wiped out the resonant cavity tube (or valve as they say in the UK).? Should have changed the capacitor out before applying power because now I just have a radiosonde paperweight!? Anyway, here is a screen shot of the signal from one meter away from the antenna before the capacitor damaged the tube. |

开云体育Hi Terry Your offer is most welcome, it requires the blessing of David which are the owner of all rights. You correction must be clearly visible for me to correct the Visio file. I have attached an image of all the export formats and I just tried to generate the Webside file (a html file and a folder with all the graphics) and it was a nice surprise to watch as a left column contains the page text clickable for fast selection. Kind regards Kurt Kurt ?? ? Fra: [email protected] <[email protected]> P? vegne af Terry Perdue ? This is a work of art! Once the Ultra’s menu structure is finalized, this could become a product similar to the ‘Nifty Manuals’. I think it could be a big seller and help reward those responsible for all their hard work. There are, however, many spelling and grammatical errors in the charts. I’d be happy to help with those if you’ll PM me. Terry K8TP
