2. TESTING CONDITION

   • 2.1 TEST SETUP
     VSWR measurement (S11): Use ROHDE & SCHWARZ ZV8 Network Analyzer with Harbour RG-142 coaxial cable: 1000mm length in free space.
   • 2.1.1 VSWR
     The table as below summarizes concern about Return loss measurement according to The frequency band is based on FWS design. The detail be shown as appendix that is from ROHDE & SCHWARZ ZV8 Network Analyzer

     VSWR Performance
     Freq(MHz)	2000	2500	3000
     Free space	1.3	1.2	1.1

   • 2.1.2 ISOLATION MEASUREMENT
     The isolation of the power divider was measured by ROHDE & SCHWARZ ZV8 Network Analyzer. The way to measured isolation is connect output ports and the other ports mount with 50 ohm matches respectively. The table as below summarizes concern about isolation measurement according to The frequency band is based on FWS design.

     isolation Performance
     Freq(MHz)	2000	2500	3000
     Isolation(dB)	-31.8	-38.9	-21.4

   • 2.1.3 INSERTION LOSS MEASUREMENT
     The insertion loss of the power divider was measured by ROHDE & SCHWARZ ZV8 Network Analyzer. The way to measured insertion loss is connect input and output port and the other ports mount with 50 ohm matches respectively. The table as below compared with S₁₂ and S₁₃ insertion loss measurement according to The frequency band is based on FWS design. The table as below have already reduced 3 dB of measurement.

     Insertion loss Performance
     Freq(MHz)	2000	2500	3000
     Insertion(S12) dB	-1.7	-1.3	-1.2
     Freq(MHz)	2000	2500	3000
     Insertion(S13) dB	-1.5	-1.2	-1.2

   • 2.1.4 PHASE MEASUREMENT
     The method to measured phase variety of power divider is connect input and output port with ROHDE & SCHWARZ ZV8 Network Analyzer. Other ports mounted 50 ohm matches respectively. The table as below compared with S₁₂ and S₁₃ phase measurement according to The frequency band is based on FWS design.

     Performance
     Freq(MHz)	2000	2500	3000
     Degree(S12)	109.6	-9.6	54.6
     Freq(MHz)	2000	2500	3000
     Degree(S13)	108.1	-8.7	56.3
