This symbol indicates that the power line switch is OFF or in STANDBY position. Safety Earth Ground This is a Safety Class I product (provided with a protective earthing terminal). An uninterruptible safety earth ground must be provided from the main power source to the product input wiring terminals, power cord, or supplied power cord set.
General Information General Information Description The X281C, P281C, and K281C adapters provide a convenient means of coupling between waveguide and coaxial systems. Power can be transmitted in either direction, and each adapter covers the full frequency range of its waveguide size. A step-like internal structure transforms the waveguide impedance to the 50 Ω impedance of the coaxial line. Option 006 Table 1 Option 006 adds two alignment holes to the waveguide flange.
General Information Option 012 Option 012 for the X281C offers a Type-N (m) connector to replace the standard 7-mm connector. Option 013 Option 013 for the X281C offers a Type-N (f) connector to replace the standard 7-mm connector. Option 013 is not offered for the K281C and the P281C. Instruments Covered by Manual The adapters covered by this manual have a two part serial number. The first four digits and letter constitute the serial number prefix.

Operation Operation Before connecting the adapter, note the precautions below. CAUTION Operating Environment Operating Procedures • Exceeding the energy and power levels shown in Table 1 may result in damage to the adapter or associated equipment. • Care should be taken to protect the face of the flange from any damage that would prevent close surface-to-surface contact. Any burring, denting, or scratching may increase RF leakage and the reflection coefficient of the waveguide connection.
Service Information Service Information Replacing the Center Conductor Contact Not all parts on the adapters are replaceable, but all of the adapters have a replaceable center conductor contact. When you replace the center conductor contact, observe the following precautions: • Before installing the new center conductor contact, apply Loctite sealant #222 to the threads of the center conductor. • Do not use excessive force when tightening center conductor parts.

Connector Types Connector Types Pin depth is the distance that the center conductor mating plane differs from being flush with the outer conductor mating plane. The pin depth of a connector can be in one of two states, protruding or recessed. Figure 4, Figure 5, and Figure 6 show a visual representation of proper pin depth for connector types for standard and option models.
