Product information is subject to change
without notice.
Scope of delivery:
1 Test Model Probe Test-256MEA
1 CB-GND cable (CB-GND cable with a length of ca. 50 mm and 0.76 mm connectors at each end).
Test-256MEA
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.
!
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.

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.
