We describe an ultra-wide-bandwidth, low-frequency receiver recently installed on the Parkes radio telescope. The receiver system provides continuous frequency coverage from 704 to 4032 MHz. For much of the band ( ${\sim}60\%$ ), the system temperature is approximately 22 K and the receiver system remains in a linear regime even in the presence of strong mobile phone transmissions. We discuss the scientific and technical aspects of the new receiver, including its astronomical objectives, as well as the feed, receiver, digitiser, and signal processor design. We describe the pipeline routines that form the archive-ready data products and how those data files can be accessed from the archives. The system performance is quantified, including the system noise and linearity, beam shape, antenna efficiency, polarisation calibration, and timing stability.

用于帕克斯射电望远镜的超宽带宽(704 至 4 032 MHz)接收器

我们描述了最近安装在帕克斯射电望远镜上的超宽带低频接收器。接收器系统提供从 704 到 4032 MHz 的连续频率覆盖。对于乐队的大部分人( ${\sim}60\%$ ),系统温度约为 22 K,即使存在强移动电话传输,接收器系统仍保持线性状态。我们讨论了新接收器的科学和技术方面,包括其天文目标,以及馈源、接收器、数字化器和信号处理器设计。我们描述了形成存档就绪数据产品的管道例程以及如何从存档中访问这些数据文件。系统性能被量化,包括系统噪声和线性度、波束形状、天线效率、极化校准和时序稳定性。
