Screen shot from a standard oscilloscope triggered on the Sync Out pulse (Please see "Measuring
output signals with an oscilloscope"). Green trace = voltage output (+U), red trace = inverted
voltage output (-U), pink trace = TTL output from the Sync Out.
Voltage output 1 V and Sync Out.
The time lag between the Sync Out output, the trigger, and the voltage output
is approximately 15 μs (+/- 2 μs)
Setup suggestions for voltage mode
The following illustrations show circuit diagrams of suggested setups. Please note that you can
use unshielded twisted pair cables (wires twisted round each other) instead of a shielding
to prevent the amplifier from picking up noise. The experimental ground can be, for example,
the amplifier's ground or a Faraday cage.
If you use the stimulus generator together with a standard MEA amplifier, you can also use the
provided 3-polar cable for directly connecting the stimulus generator to the electrode inputs
of the MEA amplifier. Please note that a shielded cable is generally not necessary if you use a
MEA1060 amplifier with blanking circuit. For more details on the recommended setup for this
amplifier type, please refer to the “MEA1060 Amplifier with Blanking Circuit” manual.
