2.7 Materials Needed
The following list represents the materials that may be used for the various field installs.
Not all materials are required for every installation.
• Coupler, Mini Circuit, ZFDC-10-21, 50 ohm BNC, Harris part number 620-2969-000
This coupler is used when a spare sample is not available. It is place in line at the
measurement point and the coupled port used for the feedback.
The coupled port has a 10 dB attenuation from the input.
• Splitter, two port, Mini Circuits, ZFSC-2-2, zero phase, 50 ohm SMA, Harris part
number 620-2964-000
This splitter is used to split a feedback signal to two exciters.
• The following three splitters are used as needed to split or combine an RF signal.
Splitter, two port, Mini Circuits, ZFSC-2-2, zero phase, 50 ohm BNC, Harris part
number 620-1563-000
Splitter, three port, Mini Circuits, ZFSC-3-4, zero phase, 50 ohm BNC, Harris
part number 620-3038-000
Splitter, four port, Mini Circuits, ZFSC-4-1, zero phase, 50 ohm BNC, Harris
part number 620-2833-000
Used as needed to split or combine an RF signal.
• Adapters, N female to BNC male, Harris part number 620-0128-000
Used to connect a BNC coupler directly to the N connector on the RF system.
• Adapter, BNC female to N male, Harris part number 620-0547-000
Used to connect the original RF system cable to feedback coupler.
• Adapter, BNC male to BNC male, Harris part number 620-0564-000
Used in Platinum transmitters to connect the feedback coupler directly to the RF sam-
ple coupler.
• Adapter TNC female to BNC male, Harris part number 620-2967-000
Used in Sigma to connect the feedback coupler directly to the breakaway couplers.
• Adapter, BNC female to TNC male, Harris part number 620-2821-000
Used in Sigma to connect original breakaway coupler cable to the feedback coupler.
• RF Cables, the number and type of each depends on transmitter type and installation.
Depending on installation, other lengths and connector combinations may be needed.
