Example 1b: Current Mode: The green trace shows the current output (+I) with a load resistance
of 10 k
; and the pink trace shows the TTL output from the Sync Out that was used for
triggering the oscilloscope

Rise time with programmed 500 mV and 50 μA pulses, 10 k
 load resistance.
Rise time (10 % / 90 %) = 3 μs
Result of Example 1: The rise time is about 3 μs for the 500 mV voltage pulse,
and about 3 μs for the 50 μA current pulse.
