Example 2b: 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 5 V and 500 μA pulses, 10 k

 load resistance.

Rise time (10 % / 90 %) = 3 μs

Result of Example 2: The kinetics and the rise time of the 5 V voltage pulse are comparable
to the 500 mV pulse. The approximate 3 μs rise time of the 500 μA current pulse is not higher
than the rise time of the 50 μA pulse.
