AD2: Using both WG channels for 0-10V

[mjacome 0]

Hello,

I see in the manual that the WG has + and - supplies, though the supplies are limited to 5V.

Is it possible to use both WG outputs in sync to do a ramp from -5 to +5V? I want to do a 0-10V sweep.

Hi @mjacome

You could use V- or W2 at -5V as virtual ground for your circuit and generate with W1 ramp from -5V to 5V. This relative to -5V would be 0 to 10V.
Note the W1/2 can drive up to 10-50mA !

Here Scope 1- (negative input) is connected to W1 W2 -5V

 

Generating ramp up and down differentially is -10 to +10V

Thank you!

To achieve these results I had to connect scope 1- (negative input) to W2 AND scope 1+ (positive input) to W1.

Hi @mjacome

Yes. I wanted to say in the above example 1- to W2 and 1+ to W1.
