Series 2280S Precision Measurement, Low Noise, Programmable DC Power Supplies
Perform Semi-Automated Testing
Right on Your Bench
Test your design over its operating voltage range
automatically or study how it responds to DC output
changes by using the Series 2280S supplies’ built-in
List Mode function. Create and save up to 10 lists of
sequenced voltage levels with up to 99 distinct voltages
in each list. The duration of each voltage level can be set
as short as 1ms or as long as 60s. Create simple linear
ramps or any custom configuration from either the front

panel or an interface bus. A single trigger will automatically
execute the list once or multiple times.

them using a Measure Sub-screen.

Controlled Rise and Fall Times
Protect Devices Under Test
Are you working on a device or a system with a high in-
rush current? Series 2280S supplies allow programming
the voltage output’s rise time to slow the voltage ramp and
avoid voltage overshoot, which could potentially damage
the DUT. The voltage fall time can also be controlled to
prevent a fast ramp down of the output voltage. Voltage
rise and fall times can be set as slow as 10 V/s or as fast
as 100V/s. Small voltage transitions can be programmed
to rise and fall as fast as 1000 V/s.

through a series of levels. The voltages were created by the list shown
in Fig. 7A.
