Description

Model 50P-1976 is a 50 Ohm relay programmable attenuator with attenuation range 0 to 127dB by 1dB steps.  It operates DC-1000 MHz and is rated for 2 Watts of RF input power.  This step attenuator is available with BNC, N, SMA or TNC coaxial RF connectors.  The attenuator has seven individually controlled steps:  1dB, 2dB, 4dB, 8dB, 16dB, 32dB and 64dB.

+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 5dB setting, the 1dB/4dB control lines must active.  For the 15dB setting, the 1dB/2dB/4dB/8dB 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).
