Can I read the signal sent to a analog output?

[bmc74]

I'm using Labview 7.0 and a scc2345. I send a waveform to an analog output and simultaneously read a signal from a digital input. I need to use the waveform (output) with the detected signal for lockin detection. How can I directly read that output? At the moment I connected the output to another dig. input but I would like to avoid that.

You could use an analog input of the DAQ device (thru the SC-2345) to read the analog output. There are SCC analog input modules for the SC-2345 that you use to wire the analog output to and then read in via LabVIEW. This would be the best option. I've included a link below to the SCC-AI modules that you could use in the analog input sockets of the SC-2345.

I hope this helps.

Actually that is more or less what I was doing (wired externally to a SCC-FT01 module) but isn't there a way to use that waveform directly from the software, without using any analog signal at all? (because of the lockin detection, any noise due to this signal is easily detected).
Thank you for your help.
