RA-31 STEPPED ATTENUATOR (7 dB)
The RA-31 consists of three high-power attenuators that can be manually switched in or out. This allows the attenuation to be increased in 1-dB steps, up to a maximum of 7 dB. It is useful for stepping the output level of a gated amplifier for nonlinear measurements. The RA-31 is capable of handling pulse power in excess of 5 KW and an average power dissipation of 5 Watts. Attenuation characteristics are maintained up to about 50 MHz with an accuracy of approximately 5 percent.
