The test system is built by using transmission lines, calibration kit, and temperature control system 利用研制的傳輸線(xiàn)、校準(zhǔn)件及溫度控制系統(tǒng),組建了測(cè)試系統(tǒng)。
The calibration kit used in high temperatures and transmission lines designed for different functions are fabricated and temperature control system is developed 然后研制了系統(tǒng)所需具不同功能的傳輸線(xiàn)及系統(tǒng)的校準(zhǔn)件,并研制了溫度控制系統(tǒng)。
In this design, the calibration and the test is done by switching the test channel . in the trl calibration, for solving the problem that one set calibration kit is not enough for three ports ’ connection, a new calibration step is added 在多端口測(cè)量系統(tǒng)的校準(zhǔn)中,為解決trl校準(zhǔn)件只有一套不夠三個(gè)測(cè)試端口連接的問(wèn)題,增加了校準(zhǔn)步驟,使得只用一套校準(zhǔn)件就能校準(zhǔn)多端口系統(tǒng)而校準(zhǔn)效果卻維持不變。
