It is usable for dc I see on this page also, I do not understand why the filter in the power supply is not sufficient?
see page in dutch Zelfbouw Filter voor de IC706
A easy and cheap filter will do the job and the company that builds the power supply especially from a network analyzer is not...
Hi you mean like this?
**broken link removed**
Isn't that a mains filter for alternating currents?
I have dc out of a switching power supply. Having problems with noise.
I do not know if I can call the output floating, mybe if the psu does not have a connection betweet to the case, the negative...
so by adding a inductor before the capacitor I can make a better filtering then alone a capacitor? Never thought at that! very nice
And how about a high pass to ground?
No it is a stock power supply in a nearly 20 year old vector network analyzer.
I have to measure what noise is coming out, it is a long time ago I did measure that!
Tomorrow I can not do that, becouse I am away.
But I think it will mostely be the switching frequency of the supply that is maybe...
I would say buy a couple of opamps they cost nothing and try it out they are very easy to use, like ne5532 orso.
If you need more current then a small opamp can deliver that is like your microcontroller, you have to make use of 4 mosfets with a couple of resistors as driving circuit...like a...
Question I have problems with a switching mode powersupply with multiple different voltage outputs like a computer PSU.
How can I get the output as clean as possible? that is very important for me.
I have a couple of options I think normally it uses a very small form factor 10.000uf capacitor at...
