Acquisition Modes and Acquisition Units
Lynx DSA User's Manual - 9240227J 5
Acquisition Modes and Acquisition Units
The Lynx 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 which 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 32678 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 will stop any acquisition in progress but will not
lose data already accumulated.
Spectrum data is cleared by the Lynx 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. 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.
Input #1 must be set for DLFC mode. Acquisition is automatically directed into
both memory groups. The memory groups are identical in size. Acquisition times
for both groups are identically 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
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 will abort any acquisition in progress but will not lose data
already accumulated.

Chapter 1 Introduction
6 Lynx DSA User's Manual - 9240227J
MCS acquisition always begins at spectrum channel #1 and progresses linearly
through the end of the spectrum, accumulating to 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 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’s 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 important note in
Using the Programming Libraries on page 7.
List Modes
The Lynx 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 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 buffer memory, one word per event, until requested and/or consumed
by the client application. Resolution of the time stamp can be set to 100 or 1000
nanoseconds.
List data stored by the Lynx in its temporary buffers can be read using the Lynx’s
Programming Libraries and energy and time-correlated spectra can then be
created from the data by custom applications.
In List Mode, the Lynx 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
important note in Using the Programming Libraries on page 7.

Using Programming Libraries
Lynx DSA User's Manual - 9240227J 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.
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 important note in
Using the Programming Libraries on page 7.
Digital Storage Oscilloscope (DSO)
Lynx 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 supports up to eight programmable SCA counters, each with its own
independent energy window that restricts counting of PHA events.
SCA Counters can operate completely independent from Input #1
(PHA/DLFC/MSS/LIST/TLIST) or Input #2 (MCS)
If using List or time-stamped List mode through a custom application, please see
important note in Using the Programming Libraries on page 7.
Using Programming Libraries
The platform-independent Lynx Software Development Kit (SDK) provides a set of
functionalities in a programming library for writing 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 from a custom program that
consumes data from MSS, LIST, TLIST, SCA, or Aux
Counters, do not access the Lynx 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 in order 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.
