Slew rate bands are not programmable. When you program a slew rate value outside the indicated bands, the electronic load will
automatically adjust the slew rate to fit within the band that is closest to the programmed value. The slew rate accuracy specification is
only applicable to slew rates within the indicated bands. Additionally,
when the transition from one setting to another is small, the small
signal bandwidth of the load limits the minimum transition time for all programmable slew rates (see chapter 2 for more information).
Below 3 volts, the maximum bandwidth of the electronic load is reduced by a factor of ten to one. For example, in the current range for
Model N3302A, the maximum slew rate is specified as 2.5MA/s, below 3 volts the maximum slew rate would be 250kA/s. Any slew rate
programmed between 2.5MA/s and 250kA/s would produce a slew rate of 250kA/s. Slew rates programmed slower than 250kA/s would
still correctly reflect their programmed value. If you are using transient mode to generate a high frequency pulse train, a reduced slew
rate might cause the load to never reach the upper programmed value before beginning the transition to the lower programmed value. So
even though the transient mode is still operational at lower voltages, a fast pulse train with large transitions may not be achievable.
