Description
Model 75PM-027-XX consists of 75 Ohm manual attenuators mounted to a 19 inch rack mountable panel. The number of attenuators in the assembly can be selected from 1 to 8. Depending on the number of attenuators the panel height is either 1RU or 2RU. The manual attenuators used in the assembly have attenuation range 0 to 50dB by 1dB steps and operate DC-1500 MHz.  The attenuators are rated for 1 Watt average RF power. The attenuators are dual rotary type (i.e. two manual knobs). The small knob is 1dB step. The large knob is 10dB step. Available with 75 Ohm coaxial RF connectors: BNC, F or N female.
1RU Example Models
75PM-027-02 SMAÂ Â (2 attenuator)
75PM-027-04 SMAÂ Â (4 attenuators)
75PM-027-03-1EP SMAÂ Â (3 attenuators, 1 empty position)
2RU Example Models
75PM-027-06 SMAÂ Â (6 attenuators)
75PM-027-08 SMAÂ Â (8 attenuators)
75PM-027-06-2EP SMAÂ Â (6 attenuators, 2 empty positions)
Empty Positions for Future Expansion
The panel mounted attenuator assembly can be ordered with empty positions (i.e. -EP) that will allow the mounting of additional attenuators for future expansion. The outline drawings show several examples of models that are fully populated with attenuators and models with attenuators and empty positions.
