Description of the MCA Communication DLL
Name MMCA_SET_GAIN
Description The function sets the amplifier coarse and fine gain.
Declaration
ERROR_FLAG CALLBACK MMCA_SET_GAIN(unsigned short unCoarseGain,
unsigned short unFineGain);
unCoarseGain
Coarse gain: 2, 5, 10, 20, 50, 100, 200, 500 or 1000
unFineGain
Fine gain: MCA166: 5000 ... 15000 * 0.0001 (if coarse gain=1000, max. fine gain=10000 )
MCA527: 5000 … 65000 * 0.0001
Return value See MCA_COMM function
Name MMCA_SET_OFFSET_DAC
Description The function sets the offset DAC of the MCA527.
Declaration
ERROR_FLAG CALLBACK MMCA_SET_OFFSET_DAC(unsigned short unValue);
unValue

Return value See MCA_COMM function
Remarks The function is only usable for MCA527.
Name MMCA_SET_MCA_INPUT_AMPLIFIER
Description The function sets the input to 'amplifier' (MCA166) or 'shaping' (MCA527).
Declaration
ERROR_FLAG CALLBACK MMCA_SET_MCA_INPUT_AMPLIFIER();
Return value See MCA_COMM function
Name MMCA_SET_MCA_INPUT_AMPLIFIER_POS
Description The function sets the amplifier input polarity to positive.
