11.5 Comparison of Output Signals in Current Mode
To show the different behavior of the output signals in current mode, there are some examples
to get an idea how the stimulus generator will deliver the stimulus pulses. The screen shots are
from a standard oscilloscope triggered on the Sync Out pulse
Example 1: Influence of the length of a current pulse 100 μs versus 20 μs with an amplitude of
1600 μA, which is at the maximum capacity of the STG3000 series (constant amplitude and load
resistance).
Example 1a: Current pulse with programmed 1600 μA for 100 μs and 20 μs interval and 10 k

load resistance.
The pulse is biphasic, and 1600 μA which is the limit of the maximum capacity of the STG3000
series. Green trace = current output (+I), pink trace = TTL trigger output from the Sync Out.
