Lynx DSA User's Manual - 9240227J vii
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 triple-
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.
Figure 1: Front View of Lynx DSA
Setup is designed to be simple, and its web-enabled set up and operation provide live spectral
display/control, energy calibration, and basic analysis.
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 provided for specialized
applications and legacy support.
The Primary User Interface - an advanced browser-based design - allows interaction with your
Inputs from almost any computer device equipped with an Internet browser, whether locally or
remotely. This minimizes the connectivity requirements for all users.
A separate Lynx Programming Libraries document is available. Ask your local representative
for more information about the Programming Libraries, if required.
