Test-256MEA

Test Model Probe for USB-MEA256-Systems

GND

Signal source

Signal ground, internal connected
to the four GND points.

The provided test model probe simulates a 256MEA with a resistor of 220 k and a 1 nF capacitor
between ground and electrode. It can be used for testing the noise level of the electrodes of an
USB-MEA256-Systems for all 252 recording electrodes simultaneously.

GND = “bath” Pad = “electrode”

220 k

1 nF

For the intention to check the noise level of the electrodes of an USB-MEA256-System without
external signals, please connect “signal source” and “signal ground” sockets with a CB-GND cable
for a short circuit. All 252 recording electrodes are internally connected to the resitor-capacitor pair.

To feed in test signals into the USB-MEA256-System via the test model probe, please connect
the signal source, for example a STG, to the “signal source” socket, and the signal ground
via “signal ground” socket to the amplifiers ground.

For ground connection and for short circuit please use the provided cable CB-GND.

The impedance between signal source and contact pads averages 120 k at 1 kHz.

Warning: The Test-256MEA may only be used together with the USB-MEA256-System

!

from Multi Channel Systems MCS GmbH, and only for the specified purpose. Damage
of the device and even fatal injuries can result from improper use.
