to allow a better noise performance. When starting an acquisition, the 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.

1Effective resolution for linear mode at ±10 V input range. Input resolution is 16 bits (0.152 mV). Lower data rates
provide higher effective resolution. The lock-in mode allows higher effective resolution. In this case, the effective
resolution is higher than RMS noise for every listed frequency.
