Acquisition Modes and Acquisition Units
Lynx II DSA User's Manual – 7096089 5
Acquisition Modes and Acquisition Units
Note:
As described below, memory groups are not supported in the web browser
interface. They are only available through the Genie interface. However, if
Compare Spectra is checked in Preferences | Miscellaneous the spectrum
from Memory group 2 will overlay Memory group 1 in the web client interface
when Combined Adv Coincidence, Combined Adv Anti-Coincidence, or Dual
Loss Free Counting (DLFC) mode is enabled. To view separately or in more
detail, please use other applications like Genie-2000 which supports displaying
multiple Memory groups.
The Lynx II supports several acquisition modes:
PHA Mode
The PHA (Pulse Height Analysis) mode acquires energy-correlated data. Each channel,
defined as an energy window, is incremented by one count for each event that falls
within the window, producing a spectrum that correlates the number of energy events as
a function of their amplitude. The energy resolution of the spectrum (number of
channels) is determined by the Input Size setting. Its range is from 256 to 32768
channels.
Input #1 must be set for PHA mode. Acquisition can be directed into either of two
memory groups. The memory groups are identical in size. Each group can store the
spectrum data and the acquisition times independent of the other group.
Spectrum data and acquisition times are stored in persistent memory, meaning that
cycling power to the Lynx II will stop any acquisition in progress but will not lose data
already accumulated.
Spectrum data is cleared by the Lynx II when changing acquisition modes for Input #1.
DLFC Mode
The DLFC (Dual Loss Free Counting) mode of operation allows real time acquisition of
events and will produce two PHA-type spectra. One spectrum contains live time
corrected counts, and the other produces the normal uncorrected counts. Memory group
1 displays the corrected spectrum. Memory group 2 displays the uncorrected spectrum.
Input #1 must be set for DLFC mode. Acquisition is automatically directed into both
memory groups. The memory groups are identical in size. Acquisition Real times for
both groups are identical when in DLFC mode.
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.
Input #2 must be set for MCS mode. Acquisition can be directed into either of two
memory groups. The memory groups are identical in size. Each group can store the
spectrum data and the elapsed sweeps independent of the other group

Chapter 1 Introduction
6 Lynx II DSA User's Manual - 7096089
MCS and PHA acquisitions are independent of each other. Spectrum data and elapsed
dwell values are stored in persistent memory, meaning that cycling power to the Lynx II
will abort any acquisition in progress but will not lose data already accumulated.
MCS acquisition always begins at spectrum channel #1 and progresses linearly through
the end of the spectrum, accumulating the residual data from previous sweeps.
MSS Mode
The MSS (Multispectral Scaling) mode, also called “ping-pong” mode, alternately
collects PHA data in two separate memory groups based on a preset condition,
collecting many spectra with extremely low latency between acquisitions. Spectra are
stored internally along with their acquisition times until requested and/or consumed by
the client application.
Input #1 must be set for MSS mode. Acquisition is automatically directed into both
memory groups.
In MSS mode, the Lynx II can be set to automatically stream (or push) data out to
listening clients at the completion of each acquisition cycle or can be set to concatenate
spectra in its internal buffers until requested by the client, or buffers run out. If data is
not requested and buffers run out, the current acquisition cycle will be extended to
prevent data loss.
If using MSS mode through a custom application, please see the important note in
Using the Programming Libraries on page 7.
List Modes
The Lynx II supports Standard List Mode (LIST), and Time-Stamped List Mode
(TLIST). Input #1 must be set to the appropriate mode to enable List mode.
In Standard List mode, each energy event is digitized by the PHA digital processor and
temporarily stored in a buffer memory, one word per event, until requested and/or
consumed by the client application.
Time-Stamped List Mode is similar to Standard List Mode, however, each energy event
is tagged with the time of arrival. Both the energy and time are temporarily stored in a
buffer memory, one word per event, until requested and/or consumed by the client
application. The resolution of the time stamp can be set to 100 or 1000 nanoseconds.
List data stored by the Lynx II in its temporary buffers can be read using the Lynx II’s
Programming Libraries and energy and time-correlated spectra can then be created from
the data by custom applications.
In List Mode, the Lynx II can be set to automatically stream (or push) data out to
listening clients at fixed periodic intervals or can be set to retain list data in its internal
buffers until requested by the client. If data is not requested and buffers run out,
eventually new data will be lost.
If using List or time-stamped List mode through a custom application, please see the
important note in Using the Programming Libraries on page 7.

Using Programming Libraries
Lynx II DSA User's Manual – 7096089 7
Auxiliary Counters
Auxiliary Counters count digital pulses supplied through a GPI/O \ rear-panel
connector. Up to two Aux counters are supported by the Lynx II.
Auxiliary Counters can operate completely independent from Input #1
(PHA/DLFC/MSS/LIST/TLIST) or Input #2 (MCS)
If using Aux counters through a custom application, please see the important note in
Using the Programming Libraries on page 7.
Digital Storage Oscilloscope (DSO)
Lynx II incorporates a multi-trace digital and analog oscilloscope. This mixed-signal
oscilloscope is included for system performance optimization and flexibility.
Single Channel Analyzer (SCA)
The Lynx II supports up to eight programmable SCA counters, each with its
independent energy window that restricts the counting of PHA events.
SCA Counters can operate completely independent from Input #1
(PHA/DLFC/MSS/LIST/TLIST) or Input #2 (MCS)
If using SCA mode through a custom application, please see the important note in Using
the Programming Libraries on page 7.
Using Programming Libraries
The platform-independent Lynx II Software Development Kit (SDK) provides a set of
functionalities in a programming library for writing a custom application where
capabilities beyond those of the supplied software are required. One such example may be
the analysis of the time-stamped List mode data from multiple detectors.
Important: When accessing the Lynx II from a custom program that consumes
data from MSS, LIST, TLIST, SCA, or Aux Counters, do not access
the Lynx II with equivalent functionalities from the web browser, as
doing so will likely result in loss of Library data because the
application running in the browser is another data consumer and will
remove buffered data to display it. This removed data will then no
longer be available to the programming library.
Ask your local representative for more information about the Programming Libraries, if
required.
