BACKGROUND
What is a Pulsar?
rotating neutron star that emits a beam of electromagnetic radiation
Think of a lighthouse

BACKGROUND
the world's largest fully steerable radio telescope.
Operates 0.1-116 GHz Discovered three new
millisecond pulsars
Green Bank Telescope

PROBLEM STATEMENT
Over the years, analytical systems have been updated.
Limited time for testing
Solution: Artificial Pulsar

CURRENT ARTIFICIAL PULSAR
Does not accurately represent real pulsar Bandwith is too small No pulse dispersion Standard signal generator

NEW ARTIFICIAL PULSAR
Larger Bandwith – (100MHz-1000MHz)
Command Line Interface
Adjustable pulse amplitude
User selectable pulse width and period
Polarization of pulses
Independent noise floor
Sub pulses and interpulses
