Fig. 3 Current output 100 μA and Sync Out.
Screen shot from a standard oscilloscope triggered on the Sync Out pulse (see "Measuring output
signals with an oscilloscope"). Cyan trace = current output (+I), yellow trace = inverted current
output (I), green trace = TTL output from the Sync Out.
Setup suggestions for current mode
The following illustrations show circuit diagrams of suggested setups. Please note that for current
stimulation, you should use shielded cables to protect your setup against electromagnetic
interference. The experimental ground can be, for example, the amplifier's ground or a Faraday
cage.
