I have see this KB before.
But I don't understand the simultaneous sampling.
"E-Series Data Acquisition Cards multiplex all acquired signals to a single A/D converter. This introduces a slight phase delay between the acquired signals. In the case of the Lock-In Amplifier, the signal to be analyzed would then be phased relative to the acquired reference signal. That phase delay would adversely affect the phase accuracy of the Lock-In Amplifier."
It mean I still can use E-series DAQ card, but the phase maybe not the real phase?
If I can use the E-series DAQ card for a Lock-in Amplifier, what should I change the Lock-in amplifier start-up kit?
Thanks
