360B/37XXXA/B Series Vector Network Analyzers

Coaxial Performance
The V Connector? (1.85 mm) was developed as an extension
of the industry standard 40 GHz K Connector? (2.9 mm). The
V Connector exhibits mode-free operation to 67 GHz. It is
assembled using procedures that are similar to those used on
K Connectors. V085 semirigid coaxial cable is manufactured
using microporous Teflon to provide a low loss, phase stable
cable for test applications.
The Anritsu Model VNAs: 373XXA and 360B/362XA Test
Set were designed for measurement of active devices. They
provide programmable step attenuators for controlling Port 1
Power as well as Port 2 test signal level. Power levels as high
as 1 watt can be measured. Internal bias tees provide dc bias
on the test port center conductor.
The test port coupler design utilizes air dielectric stripline and
offers excellent uncorrected directivity and test port match
over the entire 40 MHz to 67 GHz frequency range. Figure 2
shows a time domain display which highlights these
parameters and shows both to be greater than 20 dB. This
performance is important to the user as better uncorrected
parameters make the system less sensitive to cable/wafer
probe loss and provide a better match for the test device.
