本扫频源采用3mm返波管并参考英国Marconi—Sander公司的6600A/1系列进行研制,由于3mm返波管较8mm返波管有较大的差异,因此著者沿用了该公司新主机对较长波段分机的兼容设计思想。此外,采用了直观的数字显示和便于程控的GP—1B接口。数字显示不仅直观,而且可提高频率直接读数的精密和准确度,从1%提高到0.5%以上,这一点是由读数字显示分辨率提高后,可以更准确地调整整形网络的结果,75—110GHz范围内输出功率在15mW以上,在高频段可达到30mW以上。
The sweep source using 3mm backwave tube and the reference to the British Marconi-Sander company 6600A / 1 series developed, the 3mm return tube than the 8mm backwave tube are quite different, so the author followed the company’s new host comparison Long-band extension compatible design ideas. In addition, the use of intuitive digital display and easy to program control GP-1B interface. Digital display is not only intuitive, but also improves the accuracy and accuracy of direct readings of frequencies from 1% to over 0.5% as the readout figures show that the resolution of the shaping network can be adjusted more accurately and the results of the 75- Output power in the 110GHz range of more than 15mW, in high frequency can reach more than 30mW.
