Description
Model 50P-1953 is a 50 Ohm relay programmable attenuator with attenuation range 0 to 120dB by 10dB steps. It operates DC-2500 MHz and is rated for 1 Watt of RF input power. This step attenuator is available with BNC, N, SMA or TNC coaxial RF connectors. The attenuator has five individually controlled steps: 10dB, 20dB, 30dB, 30dB and 30dB.
+12Vdc Controlled
Each of the attenuation steps has a corresponding solder feedthru where the control Voltage is applied. Applying +12Vdc to a solder feedthru will turn on the attenuation for that step. The internal relays are failsafe to their thru path setting (i.e. failsafe to 0dB setting). An open circuit (or Ground) on a solder feedthru will turn off the attenuation for that step. Activate multiple steps simultaneously to set combinational attenuation values. For a 40dB setting, the 10dB/30dB control lines must active. For the 50dB setting, the 20dB/30dB control lines must be active. To set the attenuator to the insertion loss state (i.e. 0dB setting), all control lines must off (i.e. Ground or Open Circuit).
