Canberra Lynx - Data Acquisition Modes

Data Acquisition Modes
The various acquisition modes (dependent on the capabilities of the input) are as fol
-
lows:
•
PHA - Pulse Height Analysis
•
MCS - Multichannel Scaling
•
MSS - Multispectral Scaling
•
DLFC - Dual Loss Free Counting
•
LIST - Records all ADC events
•
TLIST - Records all ADC events and time tags each one
Pulse Height Analysis (PHA)
CHANNELS – Selection of 256, 512, 1024, 2048, 4096, 8192, 16 384, or 32 768
channels. Support for two memory groups of up to 32 768 channels each.
DIGITAL OFFSET (zero to full scale) – Specifies a number of channels to offset the
data. The offset shifts the memory assignments of the device's conversion to the left
(e.g. an offset of 4096 would shift channel 4096 down to correspond with channel zero
of the memory).
PRESET – Real or Live Time timers are 48-bit, clocked at 1 MHz, setting with 100 ms
resolution.
CONTROL – Internal or External Start/Stop control.
DIGITAL DELAY – An adjustable digital signal delay for timing applications (coinci
-
dence counting) is supported. This feature is used in place of a delay amplifier and
supports delays of 0 to 100 µs in 0.1 µs steps.
Multichannel Scaling (MCS)
INPUT SOURCE – SCA (w/pileup, SCA (w/o pileup), Discriminator, or TTL IN.
CHANNELS – Selection of 256, 512, 1024, 2048, 4096, 8192, 16 384, or 32 768
channels. Support for two memory groups of 32768 or less channels.
DWELL – Internal or External - 2 µs to 1000 s
PRESET SWEEP COUNTER – 0 to 232 sweeps.
CONTROL – Internal or External Start/Stop control.
