Canberra Lynx - Acquisition Modes

Acquisition Modes
The Lynx™ supports several acquisition modes:
PHA Mode
The PHA (Pulse Height Analysis) mode acquires energy-correlated data. Each chan
-
nel, defined as an energy window, is incremented by one count for each event that
falls within the window, producing a spectrum which correlates the number of energy
events as a function of their amplitude.
DLFC Mode
The DLFC (Dual Loss Free Counting) mode of operation allows real-time acquisition
of events, and will produce two spectra. One spectrum contains live time corrected
counts, and the other produces the normal uncorrected counts. Each spectrum may be
viewed from the web display via the memory groups. Memory group 1 displays the
corrected spectrum. Memory group 2 displays the uncorrected spectrum.
MCS Preset Mode
The MCS (Multichannel Scaling) mode acquires time-correlated data. Each channel is
sequentially allocated a dwell time (a specified time period) for accumulating counts
until all the memory has been addressed.
MSS Mode
The MSS (Multispectral Scaling) mode, also called “ping-pong” mode, alternately
collects PHA data in two separate memory groups, quickly collecting many spectra
with extremely low latency between acquisitions.
List Modes
In Standard List mode, each energy event is stored sequentially in memory, one
word per event.
In Time-Stamped List Mode, the time of arrival of each energy event is tagged
with the time of arrival. The list data can then be read using standard spectral data read
utilities and energy and time-correlated spectra can then be created from the data.
Auxiliary Counters
Auxiliary Counters are supported. If using the Lynx Programming Libraries, heed the
Caution statements before Enabling Counters. See MCA Settings | Counters.
Digital Storage Oscilloscope (DSO)
Lynx incorporates a multi-trace digital and analog oscilloscope. This mixed-signal os
-
cilloscope is included for system performance optimization and flexibility.
Single Channel Analyzer (SCA)
The Lynx supports up to eight programmable SCA's.
