Amplifier advice for simple waveform <500Hz

[lidu8]

Hello,

I would like to generate simple wave forms below 500 Hz, to generate electric fields of one tesla via a coil.

I will use a USB DAQ for this.

What kind of amplifier should I use on its output? There's a few forum discussions on this but I can't seem to find one that could be programmed through an API as well.

Any help would be very welcome 🙂

You should post to Multifunction DAQ.

This forum is for Signal Generators (aka Arbitrary Waveform Generators or Function Generators aka products that are controlled using the NI-FGEN driver).

You would probably need to create your own amplifier to feed into a tesla coil. What are your voltage and current requirements to drive the tesla coil?

Typically, DAQ output signals are limited in current drive ability and typically not more than 10mA. To drive the primary of a Tesla coil I bet you need at least an order of magnitude more than 10mA.

Thank you for your answers!

@kirsch I have moved it to the forum you suggested, thanks!

@santo_13 I have quite a lot of reading to do to be able to answer your questions, including the form of the coil/antenna required, and was hoping to find some controllable hardware first, to make it easier to learn while doing... I don't think it's realistic for me (or the most productive approach) to start building an amplifier at this stage!... 🙂

We use BEAK amplifier and drive them with an analog output.

If you look for a full software featured source for <500 Hz maybe a SMU will do the job? 

Some more information would be needed to suggest a specific unit.

Power range?

Load conditions?

Dynamic range?

Noise?

So for a start maybe look for a simple analog amplifier (if you already have an analog output) 

1 Tesla sounds like a little more current,  and since your frequency range isn't so high, a DC power supply with an analog control input?
