An analog output used as the reference voltage of another analog output

[flybing]

Because the waveform must be equal interval quantizing, and the amplitude should be easily changed, so I want use an analog output as the reference voltage of the other analog channel. How can I realize this?

Greetings,

The following example program was designed for this exact purpose:

Increasing Analog Output Resolution -- E Series

Good luck with your application.

Thanks a lot!
I've solved the problem with your answer and the example:Continuously Generating a Waveform and a DC Voltage on Multiple AO Channels.
Thus my application is perfect.
