How to outout two analog voltage at the same time in two analog output channels?

[photoszzt]

I use the BNC 2110. I want to output two analog voltage at the same time at two analog output chanels. Do I have to use multithreading? And how to do that? Thanks.

Hi,

The BNC 2110 is a connector block, not a DAQ device.

What type of DAC device are you using and what programming language are you writing with?

There is a function generation on the board and I use that to generate the signal. I use that to control a microscope.

Hi,

I don't know if these apply to whatever hardware you're using, but try these examples

Actually this does not work on my computer. It just output on one physical channel. What I want is to output on two physical channel.

Hi photoszzt,

I was able to get the example provided by Curt C to output on multiple channels. When selecting the channels in the example to use for analog output make sure to follow these steps:

1. Build and run the application

2. While the application is running press the arrow for physical channels to open the drop-down menu.

3. Press browse in the drop-down menu

4. To select multiple channels, hold the CTRL button and click each channel to be used for analog output
