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 10V/s or as fast as 100V/s. Small voltage transitions can be pro-
grammed to rise and fall as fast as 1000V/s.
Figure 6. Programmable slew rates permit controlling voltage rise and
fall rates, preventing undesirable transients during power up
of capacitive loads.
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 sim-
ple 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.
Figure 7A. Create an output sequence using the List setup screen.
Figure 7B. Use the list mode to step the output voltage automatically
through a series of levels. The voltages were created by the list shown
in Fig. 7A.
