This scope image shows the voltage (VSTR0) and current (ISTR0)
waveforms for string zero, and their turn-off fall times. Also shown
is the string power supply output (VLED), which shows very little
disturbance. For this photo string 0 is enabled with all other strings
disabled, and a 220pF capacitor in series with a 11Ω resistor in
series is placed from STR0 to GND at the device.

This scope image shows the voltage (VSTR0) and current (ISTR0)
waveforms for string zero, and their turn-on rise times and delay
from PWM rising. Also shown is the string power supply output
(VLED), which shows little disturbance. For this photo string 0 is
enabled with all other strings disabled.
