Checking modulation

#feature_request

Kurt Poulsen All Messages By This Member #138 开云体育 Hi Luis Sure. I Got two off them ? I have not experaince with it apart form the who wrote about the combo. I will of course fire it up. I will however mainly compare to my R&S CMU200/CRTU-RU above 10MHz which has BW down to 10Hz Kind regards Kurt Fra: [email protected] <[email protected]> P? vegne af CT2FZI Sendt: 9. maj 2020 00:01 Til: [email protected] Emne: Re: [tinysa] Checking modulation #feature_request ?

Leif M All Messages By This Member #135 All true. I would check FM, DSB and what ever there is. Modulation would be easier understand with a suitable SA.
Erik Kaashoek All Messages By This Member #134 ?Use any web sdr. Most have a waterfall option.

ajparent1/kb1gmx All Messages By This Member #130 To measure close in products you need a much narrower RBW typical is 30-100hz, maybe 300hz.? You also need to insure the carrier if any is not overloading the input of the SA. If true SSB source and no distortion there is only one signal that being the sum or difference of the carrier and some carrier leakage which for any competent system should be at least -40dbc or better. Its easy to do but you need a suitably narrow bandwidth system. Allison ----------------------------------------- Please post here, direct emails go to a dead letter box.

Leif M All Messages By This Member #124 How close to a carrier I can get? Many Hams, educators and me would like to see and check their modulators. That is, can I see what does spectrum of? SSB with 1kHz modulation look like. Or 300Hz and closer.
