ELVIRA Signals Analysis Workstation |
The ELVIRA Signals Analysis Workstation
provides sophisticated signal acquisition, processing, and
analysis capabilities for the IBM® PC. ELVIRA contains
preconfigured applications for the survey and processing
of common FDM, PCM, and RF signal types in a low-cost, portable
package. In addition, the ELVIRA rapid application development
environment allows users to build custom solutions by using
a variety of specialized signal processing tools. The wide
array of applications and simulated signals also makes ELVIRA
an effective communications training tool.
ELVIRA is ideally suited for signal
research and target development at the channel and emitter
levels. Users of the Models 120, 128, and 115 find the ELVIRA
network analysis and VGC content recognition particularly
helpful for configuring these complex devices. Model 320A
or Model 320B users supplement automated recognition
algorithms with ELVIRA's wide variety of analysis tools,
which identify channel contents that would otherwise be categorized
as unknown.
This inexpensive software is a very
flexible signal analysis and survey tool. Various configurations
are available: workstation, laptop, rack-mounted PC, and
software licenses.
