Measuring the switch-on/switch-off behavior of the numerous power voltages in modern CPUs or FPGAs is challenging. The different supply voltages must be applied with specific time delays ranging from a few nanoseconds to several milliseconds depending on the specific device. In addition, each voltage has recommended minimum and maximum ramp-up times that range from a few microseconds to several milliseconds. Consequently, slew rates range from a few V/┬Ás to several V/ms. During ramp-up, the difference between particular voltages should not exceed defined values.
