Problem of two Series SAW Filter.

I was double check it and it didn't matter. At this test input power level (from signal generator) is -20dBm and use an attenuator in exactly SG output and with a cable connected to SAW1. So -40dBm achieve to SAW1 and SAW1 connected with thru SMA to SAW2 and SAW2 connected with cable to SA. The insertion loss in pass band is -55dBm and attenuation in stopband is about -135dBm.(80dBc attenuation).
All screws were closed.
Is it possible to conclude that it is not a leak?
 

Setup like following.
Connection of them without cable except for SA.

SG<->SAW1<->Att<->SAW2<->Cable<->SA

Observe level of SA with changing input level of SG.
Then plot SA level versus input level of SG.
 

Repeat last test with N type cable and achieve to 120dB attenuation.
It is rg316 leak and when use N type with shielding cable it is corrected.

thanks
