MCA Stabilisation Commands:

Name	MMCA_SET_STABILISATION
Description	The command sets the peak stabilisation.
1. Parameter	Stabilisation flag	Integer value	0	turns stabilisation off
			1	turns stabilisation on (keep peak at current position)
			>1	stabilisation channel (move peak to the stabilisation
				channel and hold peak at the stabilisation channel)
2. Parameter	Peak ROI begin	Integer value	LLD<= begin < end
3. Parameter	Peak ROI end	Integer value	begin < end <= ULD, (end-begin) < 250
Results	-
Return Code	see MMCA_RESET command

Name	MMCA_SET_STAB_PARAM
Description	The command sets the peak stabilisation parameters.
1. Parameter	Stabilisation time	Integer value	default 10 sec interval
2. Parameter	Stabilisation area	long value	default 25000
Results	-
Return Code	see MMCA_RESET command

				0X40	+24V
				0X20	-12V
				0X10	+12V
Results	-
Return Code	see MMCA_RESET command
Name	MMCA_SET_HIGH_VOLTAGES
Description	The command sets the detector high voltage and controls the HV-inhibit-signal.20
1. Parameter	High voltage	integer value		0 ... 3000
2. Parameter	High voltage inhibit	long value		i = 0	Inhibit off
				i = 1	”Canberra-/ DGF-mode”, HV shut down
					if inhibit signal high
				i =-1	”Ortec-mode”, HV shut down
					if inhibit signal low
Results	-
Return Code	see MMCA_RESET command

20 The high voltages will ramp up or down by the MMCA.
