spHvSource
short spHvSource
(
short
sHvSource
)
Sets the source of high voltage.
sHvSource can be 0 for External high voltage
control, or 1 for Software control
Zero A non-zero
number
spMonSource
short spMonSource
(
short
sMonSource
)
Selects whether to read the signal or to
monitor the high voltage.
sMonSource can be 0 for data signal, or 1 for
monitoring the high voltage.
Zero A non-zero
number
spSetAvg
short spSetAvg
(
short
sAvg
)
Sets the sample average.
sMonSource can be from 0 to 300.

spReadDataEx
short spReadDataEx
(
long
*pArray
)
Reads the data from USB port.
*
pArray points to a data address. Its memory
size should be one or bigger.
Zero A non-zero
number
Zero A non-zero
number
Reads the data saved in the Eeprom of the
interfacing USB board. The data are: High
voltage (HV), RC constant, Gain, Trigger
value, Trigger source, HV source, HV
control source, the firmware version, DC
power, and the sample average.
pArray[0...1] is the current high voltage,
where HV = pArray[0]*256 + pArray[1].
spReadInfo
pArray[2] is the RC time constant.
short spReadDataEx
pArray[3] is the Gain.
(
pArray[4] is the Trigger value.
short *sRdInfo
pArray[5] is the Trigger source.
)
pArray[6] is the HV source.
pArray[7] is either data or monitored HV.
pArray[8…9] is the firmware version in
the format of pArray[8].pArray[9].
pArray[10] is DC voltage indicator, where
0: not DC, 1: yes DC.
pArray[11…12] is the sample average
(SA), where SA = pArray[11]*256 +
pArray[12].
