3-4 Basic Source-Measure Operation 2400 Series SourceMeter
®
User’s Manual
The full range of operation is explained in Section 6, “Overheating protection” and “Oper-
ating boundaries.”
NOTE Output transient recovery — The time required for the V-source to recover to its
original value (within 0.1% plus load regulation errors) after a step change in
load current is <250µsec. This does not include the response time of autorang-
ing or the second order effects on loads that are not purely resistive.
Load regulation — The voltage specification for V-source mode load changes is
0.01% +1mV. 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% x 0.2V) + 1mV = 1.02mV
Assuming a 0 to 1A change in current, the output impedance equates to 1.02m
Ω
(1.02mV/1A = 1.02m
Ω
). This level can only be achieved using 4-wire remote
sensing.
