I recently bought the 2205A scope. It works fine but I bumped into a limitation of the AWG. The output voltage range is ±2V. For my application i need a square wave of a least ±50V. Can you recommend additional hardware or suggest electronic circuits how to amplify the square signal from the AWG?
I tried your suggestion with a standard audio amplifier to see how it would perform. It did not do well. Even at low frequencies (<1kHz) the square waves lose their sharp edges and become distorted sine waves. Tube amplifiers might be more suitable but the cost and that they are not "success garanteed" made me decide to look for other alternatives first.
I came across the possibility of using MOSFETS to switch DC voltages to square waves. Is it possible to use the AWG to trigger the MOSFETS? Could you (or someone else) help me with the circuitry? I don't want to blow up my AWG.
Be aware that a square wave of 1 kHz has higher harmonics running into several hundreds of kHz even MHz.
So that is why you lose the flanks on a audio amplifier.
I you want to make a square wave of 60V or something then i would suggest using mossfets.
After some online research I found that I need a MOSFET+driver but the circuitry is still unclear. I might skip de AWG and use an Arduino + two MOSFET driver modules. I will have to write the code for the waveforms but it's a lot cheaper than amplifying the AWG: flcelectronics.com/a600.html ($5.000+)
Attached some screenshots of the output.
Default amplification (without modification) is 30 times.
There is no DC decoupling, so if you supply a signal 0 to 1 V, the output will be between 0 and 30V
And if you supply a signal between -1 and 1V the output is between -30 an 30V
There is about a 2V drop-off from the supply voltage.
