Connecting Type-N and 3.5 mm Gauges
When making connections to the calibration modules, turn the coupling
nut on the male connector, never turn the module itself. Avoid rotating
connectors relative to each other during the connect/disconnect process
as this is the main source of connector wear.
1. Hand tighten the connection to be torqued.
2. Hold the torque wrench with your thumb and index finger behind
3. Tighten the connection until the handle begins to break loose. It is
4. Reverse the order to disconnect.
When making connections to ECal modules with 3.5 mm devices, hold
NOTE
one device stationary while torquing the nut on the other device or
cable connector. Use the open-ended wrench (HP part number
8710-1770) or the spanner wrench (HP part number 08513-20014). The
torque supplied by the torque wrench can change with use. Recalibrate
it at a schedule appropriate to its amount of use.
Type-F Compatibility
Male connectors
The precision type-F interface is compatible with the entire range of
type-F connectors as defined by the Society of Cable Television
Engineer's (SCTE) Interface Practices Sub Committee. Other type-F
connector standards, such as those used by the International
Electrotechnical Commission (IEC), may have different dimensional
tolerances. Check to see that your connectors are compliant with the
SCTE specifications before mating with the components in this kit.
Particularly, check to see that the center conductor falls within a range
of 0.56 to 1.07 mm (0.022 to 0.042 inches). For more information, refer
to SCTE document IPS-SP-401.
The male pin gauge (HP part number 85099-60005) attached to the
female connector on the module can be used to determine the diameter
of the male pin. The gauge can also be used to verify the chamfer on the
tip of the male pin.
