Analog Fast Steering Mirror Controller

[lorry1234]

Hi 

I have an analog fast steering mirror controller and a NI PCI 6221 card. I am trying to control the x-axis and y-axis, so i can use it to scan anything. The file is my code to generate the signal and introduce to the x+ command on the mirror controller, but it seems like the mirror controller doesn't get the signal. When I use oscilloscope to read the voltage is only like 8 mV. I am not sure is my code wrong or my connection. Below is how i connect the NI PCI 6221 card to my mirror controller. 

(Connect the DAC0 output to X+ command, DAC1 to Y+ command.  Connect X- and Y- command to DAC ground.

Connect X & Y position out to Analog inputs.  Connect Analog ground to FSM ground (any pin))

Hey,

Have you checked your steering mirror controller current ranges? It is possible that the minimun current for this device inputs is more than the current that the analog inputs from the PCI 6221 can output.

Can you check on the minimun current required for the controller's x and y inputs?

Hello, have you solved your problem? If you did, I would really appreciate it if you shared how you solved this problem, because I have a similar problem now.
