9.3.2.2 Mask example for MCD5
The *.reg CounterChannelMask entry for a MCD5 type ’PHOIBOS 100 MCD R5c’ looks
like:
A 5 channel MCD has following mask ’00000000 00011111’ or as hexadecimal ’00 1F’.
Please note that the first ’1’ from the left is channel number 1 and the last digit on the
right side is channel 5 respectively.
Therfore all channel means
[HKEY_LOCAL_MACHINE\SOFTWARE\Specs\Hsa3500Analyzer\Phoibos-Hsa3500\100 R5c]
"CounterChannelMask"=’01 1F’
To achieve that a 5 channel detector only use channels #1,2 and 4 you have to change
to 0000000 00011010 or ’ 01 10’, i.e.
[HKEY_LOCAL_MACHINE\SOFTWARE\Specs\Hsa3500Analyzer\Phoibos-Hsa3500\100 R5c]
"CounterChannelMask"=’01 10’
