Is there an output switch at the analog front end of PXI-6723 and PXI-6713?

Question

I was reading the analaog output user manual and i could not find this. Is there any output switch just before the analog output of each channel for PXI-6723 and PXI-6713? I am would like to have total isolation between when these output are not needed. If yes, is there any specification to refer to?
Thanks.

Hello Chris,
     I would recommend having a look at the examples in the LabVIEW
example finder to start with. In particular i would look at 'Cont Gen
Wfm-Ext Clk.vi' This is a basic example that allows you to output a
waveform through the card and source an external clock source to do
this. I would recommend exporting the sample clock that you wish to use
from the 4462 on one of the RTSI lines and then setting this as the
sample clock source for the Analog output card.
Another good example to look at is the 'Cont Gen Voltage Wfm-Int Clk
non regeneration.vi' This does not regenerate the same waveform in the
buffer but instead creates a new waveform to output after the previous
one has been written to the buffer.
It should be noted that there may be some gliltching if you are
updating the waveform. This is because the buffer will already have a
waveform in there to output before you input the new one so a new
frequency may not have an exact number periods that fit into the
pre-defined buffer. If you are looking to generate dynamic waveforms
then the best option for the best results would be one of our arbitrary
waveform generators here.
Good Luck,
