5、网分用法

时延测试：

Format ->Delay

Scale Ref -> AUTO SCALE

Marker Search -> TRACKING【ON OFF】这样以后把Marker 调到子带上

增益测试：

Formate ->Gain

Marker Fctn -> marker search[max] -> tracking[on off]-> search max

边带抑制：

先把Marker1打到边带，再打Marker2打到距离Marker1 400K处。

All off -> marker -> marker1[freq] -> all off ->marker2[freq];

All off -> marker -> marker1[freq] -> all off ->marker2->mode menu -> ∆REF1->相对偏移频率

带外抑制不够

射频波动：

增益过高：
