Re: A CLOSE LOOK TO LOW COST NOISE GENERATORS

Sorry again Roger, you are happy to write a lot of extra which not helps anybody but please must admit that in your first post you mislead me and all and after you write a lot to cover up making a big book of it. Best regards In my first post on this device I gave a link to a review of the BG7TBL n...

Re: A CLOSE LOOK TO LOW COST NOISE GENERATORS

Sorry again Roger, but you first made a big fuss about nothing. In your first post about the noise generator you only posted the guy telling the thing is junk and not to buy. If nobody commented about this and listened to you nobody buys the noise gen and nobody does any test. Then later you write ...

Re: A CLOSE LOOK TO LOW COST NOISE GENERATORS

Sorry Roger, first you write the noise gen is no good, you give a reference that says it is a Chinese junk and we must not buy it, now you say it is better and we can use it. All this very confusing to me. It seemed that glovisol did a good job using it. So must I buy or not buy. Must I buy and mod...

In this thread I wish to look deeper into this matter. This is fruitless polemising to me and this is my last post on the subject. I am surprised ...

Re: A CLOSE LOOK TO LOW COST NOISE GENERATORS

One does not have to spend $600 USD for a quality noise source. Units that are properly designed and don't have heat problems are available for under $100 USD. These products have specifications for the product and correction curves for receiver sensitivity for some models. You can see the specs and...
