5
PRESETLENLO
Low word of preset run length
6
PRESETLENHI
High word of preset run length
7
PRESET
Preset type (0: no preset, 1: real time, 2: live time,
3: output events, 4: input events)
8
RESETINT
Reset time in microseconds
9
TAURC
Preamplifier RC decay time in microseconds
(unused for reset preamplifier)
10
AUTOSLEEP
Auto sleep mode, as defined in command 0x46
11
SLEEPDELAY
Delay before entering sleep after end run (in
seconds)
12
SLEEPMODE
Manual sleep mode, as defined in command 0x47
13
STATSMODE
Sets the response to the 0x06 “Read Run
Statistics” command. STATSMODE=0 (default)
yields the short response (21 bytes).
STATSMODE=1 yields the long response is (29
bytes, including UNDERFLOWS and
OVERFLOWS).
14
WAKEDELAY
Delay before exiting sleep (10 ms units)
Appendix C. GENSET Specification
Five GENSET tables each define an MCA format. See §2.42.3 for details.
ID
Parameter
Description
0
NUMGENSET
Number of GENSET parameters NOT including
NUMGENSET and GENVERSION (used
internally)
1
GENVERSION
Version of the GENSET (used internally)
2
MCALEN
Number of spectrum bins
3
MCALIMLO
Lowest spectrum bin (allows offset spectrum)
4
MCALIMHI
Highest spectrum bin
5
BASEBINNING
Number of bins baseline values combined into
one bin in baseline histogram (power of 2)
6
BLCUT
Baseline cut value, in percentage of peak value in
baseline histogram. Standard value is 5%.
Expressed as x * 32768.
7
BINMULTIPLE
MCA bin size in terms of the minimum.
8
BINGRANULAR
Bin granularity (as defined in command 0x84: 0
== very fine, etc.)
9
GAINBASE
16-bit base gain setting. (Higher value == higher
gain). This value is modified per-peaking time by
the GAINTWEAK table in the PARSET.
10
SWGAIN
The discrete switched-gain value corresponding to
GAINBASE
11
DGAINBASE
The 16-bit unsigned mantissa of the digital fine
gain trim corresponding to GAINBASE
12
DGEXPBASE
The 4-bit signed exponent of the digital fine gain
trim corresponding to GAINBASE
13
NUMSCA
Number of active SCA windows
