MCA166-USB
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
MCA Detector Power Commands:
Name MMCA_SET_PREAMPLIFIER_POWER
Description The command sets the preamplifier power.
1. Parameter Preamplifier switch integer value 0X80 -24V
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 -
20 The high voltages will ramp up or down by the MMCA.
