Analog Output Signals
75
Current output 200 μA and Sync Out.
The time lag between the Sync Out output and the current output is approximately
15 μs (+/- 2 μs) if continuous mode is enabled and 50 μs (+/- 2 μs) if continuous mode
is disabled.
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.
