Chopping Enabled: This mode provides very low noise with lower output rates. Chopping does not eliminate the offset error and drifts caused
by input resistors. Noise performance depends on the selected analog input range and the chopping mode. The analog input is always operated with
chopping mode in order to optimize the offset drift and to allow a better noise performance. When starting an acquisition, input data rate (Samples
per second) can be selected according to the needs of each test. Higher data rate provides higher RMS noise. Analog inputs are reversed and then
calculated as an average of two conversions in order to reduce the offset error.

Effective resolution for linear mode at
±
10 V input range. Input resolution is 16 bits (0.152 mV). Lower data rates provides higher effective
resolution. The lock-in mode allows higher effective resolution. In this case, effective resolution is higher than RMS noise for every listed frequency.
