PHAHardwarePresent=0
This Boolean option specifies whether PHA baseline and window voltage control hardware is implemented. Enter 0 for none or any non-zero value if present. The default is 0 for no PHA baseline and window hardware interface.
PHAHardwareType=0
Specifies the PHA acquisition type. The default is zero for the traditional PHA acquisition (scan baseline and window voltages across the voltage range). If PHA multi-channel analyzer hardware is available (JEOL 8230/8530 and Cameca SX100/SXFive), set PHAHardwareType to “1” for fast MCA PHA acquisition.
PHAHardwareType = 0 for traditional PHA hardware acquisition (the default)
PHAHardwareType = 1 for PHA acquisition using multi-channel analyzer (MCA)
PHAGainBiasPresent=0
This Boolean option specifies whether PHA gain and bias voltage control hardware is implemented. Enter 0 for none or any non-zero value if present. Note that the Gain and Bias interface may be enabled even if the Baseline and Window interface is not. This is to allow the user to leave the PHA baseline and window parameters "wide open" and instead utilize the microprobe's gain and bias adjustments to keep the pulse height properly adjusted. This method is actually preferred for the best quantitative results.
PHAGainBiasType=0
Specifies the PHA gain and bias hardware type. Not used at this time.
PHAInteDiffPresent=0
This Boolean option specifies whether PHA integral/differential control hardware is implemented. Enter 0 for none or any non-zero value if present.
PHAInteDiffType=0
Specifies the PHA integral/differential hardware type. Not used at this time.
PHADeadtimePresent=0 ! SX-50/51/100 only
This Boolean option specifies whether PHA deadtime control hardware is implemented. Enter 0 for none or any non-zero value if present. This flag is usually set true if the hardware interface supports an "enforced" non-extendable deadtime on the system.
PHADeadTimeType=0
Specifies the PHA deadtime hardware type. Not used at this time.
PHACountTime=.5
Specified the default count time for PHA distributions. The valid range is .1 to 1000 seconds. The default is 0.5 seconds.
PHAIntervals=5
Specifies the default number of PHA measurements (intervals) for PHA distributions. The valid range is 5 to 500 intervals. The default is 20 intervals.
PHAAdjustPresent=0
Use this flag to specify if the hardware interface supports automatic PHA adjustment. Currently only the SX100/SXFive interface supports auto PHA adjustment (not currently implemented).
BiasScanCountTime=0.5
BiasScanIntervals=40
GainScanCountTime=0.5
GainScanIntervals=30
These parameters are used to set the PHA bias and gain scans performed in the PHA dialogs. See the parameters defined in line 36-41 in the SCALERS.DAT file for more information.
PHAFirstTimeDelay=0.0
This parameter is used to delay the program after the PHA parameters are set for the very first time. This can be used to deal with problems in the detector count rate and bias amplification response time when a large bias voltage change is applied. The default value is 0.0 (no delay) and the range is zero to 100 seconds. Note that this delay is only applied after the first time the PHA bias is set within the program for each spectrometer.
PHAMultiChannelMin=0.805 ; Cameca MCA PHA minimum x-axis voltage
PHAMultiChannelMax=5.637 ; Cameca MCA PHA maximum x-axis voltage
These parameters are for demo and Cameca interfaces only that support the multi-channel analyzer (MCA) PHA hardware. The default values are indicated above but might need to be modified to 0 and 5 volts if the instrument is a “newer” Sx100 or SXFive and has "dynamic baseline hardware”.
