We are rather new to this device and have been getting to know it better that we might use it for the 3-omega technique in research, however, we have come across a stumbling block.
As a test, we set the lock-in in such a way that it takes the internal frequency it produces, transfers that frequency to a speaker, which then is relayed to a microphone, the signal from which returns to our lock-in through the A input.
We know that the voltage produced should be about .08V, but the voltage measured on the return is a laughable .008V! Any ideas on why this is happening?
Our setting are at 0 Degree Phase, 1 kHz, 1 V Amp, 1 Harmonic.
Any and all help would be appreciated, and thanks in advance!
