PWM signal with usb-6000 digital output

I see.  Thank you for the explanation.

I am trying to drive a ESC controller for a motor with pulse-width modulation.  I want to do this with a small circuit.  I have done some research and was wondering if I can do this with a pulse width modulator?  If so, do I need a MOFSET as well?

To keep things simple, all you need is an Arduino. If you want to test the ESC manually, you can buy a cheap $4 servo tester.

What is your end goal? to control the speed of a BLDC motor using ESC from LabVIEW? if yes, Arduino is the simplest way, or if you need a more professional solution, what is your budget?

As I mentioned in my original question, my end goal is to use an electronic circuit, not an arduino.  And yes I am trying to drive a BLDC motor.

I am much more interested in optimizing my current setup to be compact, which is why I don’t want to use an arduino.  I don’t have a budget per se, but I need to keep it pretty cheap.

If it matters at all, I work in a research lab, so I already have certain resources at my disposal such as basic electronic components, NI daqs, and power supplies.

Arduino or other Arduino-like development boards are very versatile and save you a lot of time and money.

If you want the absolute minimal circuit to operate an ESC, try the IC555 based circuit - https://elonics.org/servo-motor-controller-tester-circuit-using-555-ic/

Check for USB Servo Controllers like the range from Pololu - these are compact and can be automated using the computer.
