Protection
The 2281S provides several methods for ensuring that the source remains within certain values. This
helps to protect the device under test (DUT) from damage.
The protection settings that affect the source are:
(on page 2-101). This is the voltage at the instrument terminals.
(on page 2-102). This is the current at the instrument terminals.
(on page 2-104). This is the sourced voltage value at the device.
The 2281S also provides overtemperature protection to prevent damaging heat build-up.
