vide fault status outputs or control an external
relay or status lamp. Series 2280S supplies can
be controlled via their built-in GPIB, USB, or
LAN interfaces. The USB interface is test and
measurement system (TMC) compliant. The LXI
Core compliant LAN interface supports con-
trolling and monitoring a Series 2280S supply
remotely, so test engineers can always access
the power supply and view measurements, even
if they’re located on a different continent than
their test systems.
To facilitate production test software develop-
ment, native National Instruments LabVIEW™
drivers, IVI-C and IVI-COM drivers are available
on the Keithley website, www.keithley.com.
