Amplifier Input & Signal Output Connections
The SPP-100 utilises a dedicated SPP-100-HS Preamplifier Headstage and this
must be connected via the 4-pole Lemo socket on the left-hand side of the front
panel. When inserting, ensure the key-way marked with the red dot is aligned
correctly.
On the right of the front panel is a BNC socket which outputs the amplified signal
in the range ±10V.
This output should be connected to an ADC input on your chosen DAQ interface.

Headstage Electrode Connections

Where possible, it is recommended that micro-electrodes are attached directly to the
headstage input so that the lead length between the headstage input and the electrode is
minimised; even a few centimetres of lead may result in substantial mains interference
(pick-up).

Metal Micro-electrodes

Metal microelectrodes may be connected by using an electrode holder (part no: NL04 or
NL08).
