User’s Manual xi
Preface
The Lynx™ Digital Signal Analyzer (DSA) is a fully integrated 32K channel signal
analyzer offering advanced signal processing filters and digital stabilization.
With its multiple counting modes, including PHA, MCS, time stamped list and
multi-spectral scaling, Lynx supports virtually every counting application right out of
the box. All current spectroscopy detector types are supported by the built-in tri-
ple-range dual-polarity HVPS.
This User's Manual is intended for the readers who will use the Lynx in their facility
to acquire spectroscopic data; the installer or technician who will initially set up the
system with other measurement and network equipment; and for the person who may
infrequently make a sophisticated adjustment to a parameter or setting. These may all
be one person or a staff. The complexity of the applications for which Lynx may be
used, and the setup and personnel involved, presumes a working level of knowledge or
ability for the different setup or options. We believe that this manual will serve each
required procedure or operation adequately with its descriptions.
Setup is designed to be simple, and its web-enabled set up and operation provide live
spectral display/control, energy calibration, and basic analysis. Online Help is built in
to guide you to the information you might need for your setup and operation.
Because the Lynx is designed to be operated in a diversified computing environment,
it supports multiple modern communications technologies using 10/100 Ethernet for
easy LAN or WAN access. USB, and Modem and wired RS-232 support are also pro-
vided for specialized applications and legacy support.
The User interface - an advanced Java-enabled browser-based design - allows interac-
tion with your Inputs from almost any terminal or computer device equipped with an
Internet browser, whether locally or remotely. This minimizes the connectivity re-
quirements for all users.
A separate Lynx Programming Libraries document is available. Ask your Canberra
representative for more information about the Programming Libraries, if required.

1. Introduction
The Lynx™ Digital Signal Analyzer (DSA) is the most advanced, full-featured
Multichannel Analyzer (MCA) ever offered. It is a 32K channel integrated signal ana-
lyzer based on advanced digital signal processing (DSP) techniques.
This manual describes the capabilities of the Lynx DSA and its Web-browser-based
control software. Setup and interaction with the Genie 2000 software is reviewed, as it
relates to the Lynx MCA. System setup details for the Lynx system are provided, and
User instructions for data acquisitions is also described.
Comprehensive online help is provided by the Lynx system through its user interface.
Select the Help link on the webpage you are viewing for context-sensitive informa-
tion. Quick-Start and Setup steps gloss over details, as a mere 'refresher'.
Quick-Start Information
New, Out-of-the-Box system? Follow the Quick Setup Summary in Appendix B
A User (you) may do the following to quickly access the Lynx (in most cases):
•Connect and set up the Lynx for a network connection; see Appendix B. Then,
from your computer, launch your Internet browser (e.g., Internet Explorer).
•Enter the URL for your Lynx DSA : _______________________________
The default URL of http://10.0.0.3/ is factory preset. If you still cannot
access the Lynx, STOP, and contact your Lynx administrator.

Key Features
The Lynx includes a full complement of control interfaces for the following: sample
changers, acquisition, external start/stop, coincidence gating, and auto pole/zero.
•Support for virtually all detectors used in gamma, x-ray and alpha spectroscopy
with up to 32K channels of spectral memory.
•Dual user interfaces:
–Full featured acquisition/analysis capability through CANBERRA's
Genie™ 2000 and Apex®spectroscopy software.
–Live spectral display, acquisition control and calibration via built-in web

4 Lynx™ Digital Signal Analyzer

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.
