Hi, I have a basic DAQ question - sorry it may sound silly ...
If I am using an optical chopper and a lock-in amplifier (LIA), say optical chopper is working at 3kHz. At the output end of LIA, may I use a sampling rate higher than 3kHz? for example, may I use a DAQ card at 300kHz to read it? Will it cause any problem (such as accuracy, precision etc)?
Thanks.
