6.4 Artifacts on All Channels
You see strange artifacts on all channels. This behavior can be caused by an insufficient supply
power. Please see the Technical Specifications section. If the voltage drops beyond a critical level,
the amplifier cannot operate properly, resulting in artifacts or in a saturation of the amplifier.
Possible causes:
? The cable connecting the amplifier to the power supply, that is, the MCS high grade cable
leading from the amplifier to the data acquisition computer if you have a MEA-System,
is too long. The applied voltage is not high enough for operating the amplifier.
 Use a shorter cable, if possible, or try another power supply with a higher output power.
MCS high grade cables with a total length of up to 3 m and the isolated power supply IPS10W
are recommended for the MEA-System.
? You have connected too many amplifiers to your power supply. The isolated power supply IPS10W
that is integrated in your data acquisition computer if you use a MEA-System can supply power
for up to three standard MEA amplifiers .
 Use an additional power supply for operating the amplifiers or reduce the number of amplifiers.
? The supply power is too low for operating the amplifier. This is especially likely if you use a custom
power supply.
 Contact your local retailer, describe the problem and your hardware configuration, and ask for
a power supply that is suitable for your amplifier.
