I'm recently reading the code of Neuroscan, in the preflight part of this signal source module, it checks a parameter called 'LSB' like following,

PreflightCondition( fabs(Parameter( "SourceChGain" )( ch )-LSB)<(1E-3) );

Is anybody know what LSB is short for?

Thanks~

Lynn,

LSB stands for least significant bit and corresponds to the conversion factor from A/D units into micro Volts. You can get the correct factor using the NeuroscanGetParam program that comes with BCI2000.
