ME-Systems
Select 1 dimensional if you are using a ME-System (generally used for in vivo or special in vitro
applications). ME-Systems are available with different channel numbers. Define the number
of channels provided by the data acquisition (MC_Card or USB-ME), and specify how many
electrodes (data amplified by the main amplifiers, for example, a MPA and a following filter
amplifier) and how many analog inputs (for example, from a temperature controller or
a microphone) are present. For the electrode channels, the original signal is calculated
automatically according to the gain settings in MC_Rack. Signals on the analog channels
are recorded "as is", with no respect to the gain.
Deselect the option Digital Input Channel, if you do not want to use the digital input channel.
One of the digital input bits can be used for triggering the recording on a TTL output of the
stimulator, for example. A typical configuration of a ME64-System would be 63 electrodes and
a digital channel. Please note that the use of the digital input channel is available on the cost
of an analog channel, that is, if you have an ME16-System and want to use the digital channel,
for example for synchronizing stimulation and recording, you could only use a maximum of 15
electrode channels. Make sure that you select the digital channel if you want to trigger the data
analysis and/or the recording.
Hint: Deselect the option Digital Input Channel, if you do not need a digital channel. Otherwise
the number of electrode recording channels is reduced by 1!
