SUMMARY
The output of the SR830 Lock-In Amplifier changes with sensitivity settings due to the amplifier's ability to handle noise signals. At a sensitivity of 10 nV, the output reads 5 nV/sqrt(Hz), while at 20 nV sensitivity, it increases to 10 nV/sqrt(Hz). The discrepancy arises because the amplifier may saturate at lower sensitivity, leading to incomplete measurement of noise signals. Thus, the higher sensitivity setting provides a more accurate representation of the noise level.
