Basic Source-Measure Operation

Load regulation – The voltage specification for V-source mode load changes is
0.01% +100µV. This means that on the 200mV range, the load current can be
changed from zero to full scale with less than 1.02mV of error. Calculation:
error = (0.01%
×
0.2V) + 100µV
= 0.02mV + 100µV
= 0.12mV
Assuming a 0 to 100mA change in current, the output impedance equates to 1.2m
Ω
(0.12mV/100mA = 1.2m
W).
This level can only be achieved using 4-wire sensing.
Compliance limit
When sourcing voltage, the SourceMeter can be set to limit current (from 1fA to 105mA).
Conversely, when sourcing current, the SourceMeter can be set to limit voltage (from 200µV to
210V). The SourceMeter output will not exceed the compliance limit.
Table 3-1 summarizes compliance limits according to range. See Section 5 for more details
on compliance limits.
