MONITORING UNIT
The monitoring unit shows the selected channel, gain or corner frequency as a DC voltage.
(
9
) CHANNEL monitor connector
BNC connector providing the monitor signal for the selected channel for reference
(range: -8V…+7V) , e.g. channel 0 is monitored by –8 V or channel 9 is monitored by +1V.
In single ended mode the monitor output is +9V.
(
10
) HIGHPASS monitor connector
BNC connector providing the monitor signal for the selected corner frequency of the highpass
filter (range: +-8V…+7V).
(
11
) GAIN monitor connector
BNC connector providing the monitor signal for the selected gain (range: +1V…+10V).
(
12
) LOWPASS monitor connector
BNC connector providing the monitor signal for the selected corner frequency of the lowpass
filter (range: -8V…+7V).
(
13
) OUT connectors
BNC connectors providing the extracellular recorded signal. The signal is filtered with the
selected corner frequencies and amplified with the selected gain. In referenced recording
mode one channel shows the reference voltage.
Important
: The signal of the reference electrode at the OUT connector is filter and amplified
as well. In contrast, the difference between signal at the recording electrode and signal at the
reference electrode is formed from the raw signals. The raw signals are not available.
