要想學(xué)會測試, 首先要學(xué)會校準(zhǔn)
1. 是德科技 (原Agilent)網(wǎng)絡(luò)分析儀校驗過程
按 prest → 選 ok → start(設(shè)定起頻 0.5 G or 2 G) → stop (設(shè)定始頻 2.5 G or 3G 6G 8.5G) → sweep(掃描?) setup → points → 輸入效驗點(diǎn)數(shù)(201x1 401x1 901x1)→ Display → Num of Traces (1-8) 選擇 → Allocate Traces(選擇顯示界面) → Format → Tr1 SWR Tr2 SWR → MeasTr1 s11 Tr2 s22 → Cal → Correction(on) →Calibrate → 2-port cal或4-port cal → Reflection → port1(open) →port1(short) → port1(load) → Return → Transmission(對接) → port 1-2 Thru → Return →Reflection →port2open) →port2short) → port2(load) → Return → Done(完成效驗) → Save/Recall → Save State →選擇State 01-08 的任意一個將驗好的波形保存在里面。
2. 是德科技 (原Agilent)網(wǎng)絡(luò)分析儀設(shè)定規(guī)格
選擇需設(shè)定規(guī)格的窗口 Tr1 Tr2 or Tr3 Tr4 → Analysis → Limit Test →Limit Test(on) →Limit Line(on)
