Ovo je jako dobar software.

Cudo funkcija i merenja ima! Ima i signal generator u sebi.

Probao sam ovaj programčić sa nekim malim šugavim mikrofonom i evo šta sam dobio na onom malom TDA2030A...

Probaću još jednom sa 50% snage, ali kad izađem iz sobe.
Ovo je brutalno za uši....

Evo ponovljenog testa:

Da li je ovo ok?

o ovom programu moglo bi se pisati u novoj temi. mislim da je potrebno baždarenje sistema prije bilo kakvih mjerenja. i još,pretpostavljam da se ovde mjeri i distorzija same zvučne karte...

Kuku, šta će ti mikrofon Smile

Izlaz pojačala na ulaz zvučne (Line in), preko razdelnika ako treba mada nije neophodno za napone amplitude manje od 1V.

Ne daju mi da se igram...

u svakom slučaju treba dobro pročitati svih 163 strane ako se želi dobro iskoristiti cijeli program... Smile

Jedan kanal izlaza možeš direktno da spojiš na jedan kanal ulaza, a drugi kanal propustiš kroz to šta testiraš pa možeš da meriš i fazni pomeraj, isto ovako nacrta grafik.


Princip je valjda isti i za ovaj program kao i za druge tog tipa Smile Sad vidim da ovaj manual ima i pomalo teorije, lepo Smile

Daj neku skicu toga, da bi bio siguran da sam te dobro razumeo...

Izmenio sam samo sliku iz manuala, pogledaj šta tamo ima Smile

Shvatam...
Hvala. Probaću ovih dana čim nahvatam malo vremena da pripremim aparaturu i pročitam par stranica... Smile

Raspored sa oznacenim elementima i vodovima bi trebalo da bude dovoljan da se u nekom programu iscrta pcb... ako bude nekih nejasnoca pitajte...zvucnik se iskljucuje pri ubadanju slusalica zato sto je pojacalo namenjeno prvenstveno za kucnu upotrebu, preklopnik za distorziju nemora da bude za print montazu, moze standardni klip-preklopnik koji se zicama spoji na pcb...

Pretpostavljam da bi ova dva elektrolita trebala biti ovako polarisana?

Ja sam pratio prema TDA2030...
3 i 5 pin preko otpornika...
Nema razloga da bude drugačije...

@TDA Sad pogledah temu … Za ona merenja sa zvucnom karticom, naravno trebas da ides na direktnu vezu (atenuator i sl).
Sa mikrofonom je neka totalno druga prica u pitanju, prvo za to ti treba specialan kalibracioni mikrofon + prava "gluva soba" + ozbiljna zvucna kartica koja ima adekvatan pre-amp za mikrofon.

@mikikg
Možda ću danas imati vremena da probam.
Mislim da sam te jednom već pitao za atenuator kad je bilo reči o Wien-Bridge oscilatoru, ali nije na odmet da pitam još jednom.
Koliki maksimalni napon smem da dobijem posle atenuatora i koliko snažni otpornici trebaju da budu?

Mislim da sam završio precrtavanje pločice za gitarsko pojačalo sa TDA2030A. Evo par sličica, pa ako neko bude imao malo vremena bilo bi lepo da ih uporedi sa orginalnim nacrtom da li mi se omakla koja greška.

Ukoliko nekom bude zanimljivo okačiću i Sprint fajl.

ako može stati po pitanju veličine slobodno okači - ja bi volio da imam ovo u magacinu. usput,mogao bi i baciti oko na to što si uradio pa makar i metodom slučajnog odabira.

Zaboravio sam dodati APEX na PCB.
Kada Mile bude potvdio da je sve ok dodaću njegov potpis i otvoriću novu temu...
