the test system is built by using transmission lines, calibration kit, and temperature control system 利用研制的傳輸線、校準(zhǔn)件及溫度控制系統(tǒng),組建了測試系統(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測試端口連接的問題,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。
