#SNAsharp - Twitter Hashtag

over 3 years ago

le principe est de générer un signal PWM ( à 65khz) avec un arduino Nano, il est filtré en passe bas et on récupère un joli sinus entre 20hz et 30khz à la sortie. Ensuite la mesure de transmission se fait avec un ampli-log. ça se pilote avec #snasharp (PC/Linux)

@F8BXI Merci d'avoir relayé la nouvelle version de #SNASharp, c'est un petit évènement, la dernière remontait à 19 mois en arrière :)

New version of #SNASharp +Huge improvement on layers display, now the soft work fine (and fast) with latest version of Mono. + A lot of new analyzer supported + Some minor bugfix Please RT https://t.co/vl3C2KVe10

@gmagiros If you have a NWT500, NWT300 or NWT70 scalar analyzer, you can use #SNASharp to caracterize your crystal. Some details here : https://t.co/1GbrJ9AENX

@trc_wm Hi Niels, You can also use #SNASharp and a compatible scalar network analyser to fastly determine crystal motional parameters. Additionaly the program compute loading capacitors and impedances matching values for a given bandwith. This is the results for a color burst crystal.

Version 2019_07_08_0 of #SNASharp is available. + Fix a regression ( with D6 analyzer only) sadly added in previous revision + Swap F1 et F2 hotkey ( now F1 decrease and F2 increase zoom range) + Save / Restore VFO frequency ==> https://t.co/vGvO1xHaKi
