1 OSR 10-19 will set the ADC in 2x mode with the same parameters of OSR 0-9, this will approximately double
the unit’s measurement rate.
2
ADC noise increases by approximately √2 when OSR is decreased. Note that this is not the unit
measurement noise levels.
3 Values based on 1000 data points per measurement.
6.2.3 Voltage Source and Measurement Specifications
Warning: Do NOT attach external voltage sources to either SMU module as this may result in
damage to the unit.
6.2.4 Current Measurement Specifications
The current measurement of the Ossila Source Measure Unit is spread over 5 ranges. Each range has
a different maximum current, accuracy, and resolution. As the range number increases, the maximum
measurable current decreases, but the accuracy and resolution increase.

5 ± 20 μA ± 10 nA 1 nA 100 pA < 10mV
1 Accuracy has been measured at the maximum current of that range.
2 Noise measurement at the highest OSR (9).
