Abstract :
We report the development of a self-contained multi-band dual-polarization receiver system, simultaneously sampling signal voltages in 10 tunable bands across 100-1500 MHz wide spectral span. The primary motivation is to use this receiver with a single large aperture to enable full-Stokes tomographic probe of the pulsar emission cone, also opening attractive possibilities for other astronomical investigations. The tests and observations carried out using this system at the Green Bank Telescope (GBT), and the preliminary results from pulsar observations using GBT will be presented. (On behalf of the RRI-GBT Multi-Band Receiver Team).
