Hi Lacertae,
Unfortunately, the PCI-MIO-16E-1 (PCI-6070E) does not allow you to generate two individual analog signals. There are two factors that make controlling two output channels impossible.
First, E-series boards rely on the DAQ-STC chip to provide the timing for the board. In the E-series devices, only one Analog Output update clock exists to control the timing of the analog outputs. What this means is that when you start the output on Channel 0, the update clock for both channels is started. There is not a second update clock available to control the start of the second channel independently.
Second, there is a limitation in the NI-DAQ drivers that only allow you to configure one output group. Therefore you can only specify properties for one group
and all channels that you wish to use must be in that one group.
With that said, you can program your analog data generation to appear as though there are two analog signals generated independently. This is described in a knowledge base document on our website:

The only way to truely achieve independent control of two analog output signals is to split up the two output channels between two separate E-series boards.
