5.3 Insufficient Power
You see no signals or strange artifacts on all channels. This behavior can be caused by an
insufficient supply power, indicated by a flickering or dark power LED. Please see the PGA data
sheet for more information on the supply power requirements. If the voltage drops beyond
a critical level, the amplifier cannot operate properly, resulting in artifacts or in a saturation
of the amplifier. MCS standard cables with a total length of up to 3 m and the isolated power
supply IPS10W are recommended for operating the PGA.
Possible causes:
? Loose cable or bad contact. The power distribution from the IPS10W in the connected computer
is obstructed.
 Unplug and reconnect the 68-pin MCS standard cable connecting the PGA with the data
acquisition computer. Make sure the connectors are properly plugged in and not tilted.
? The output power of the power supply is too low for operating the amplifier. This is especially
likely if you use a custom power supply, or the power supply has a technical defect.
 Please check the output power of the power supply and compare it with the PGA data sheet.
Contact your local retailer, describe the problem and your hardware configuration, and ask
for a power supply that is suitable for your amplifier.
