41-180-022 Pickering PXI Dual DC to 3GHz Programmable Attenuator Module

The Pickering 41-180 PXI DC to 3 GHz Programmable Attenuator Module is manufactured with either one or two independently programmable attenuators in a single width 3U PXI module. The attenuators use high reliability mechanical switches to operate binary weight attenuator pads, providing attenuation values from 0 to 63dB in 1dB steps. Operating time is typically just 5ms, ensuring fast setting.

The module is ideal for conditioning the signal levels from devices under test and ensuring that measuring instruments are operating close to their optimum operating point for noise and linearity. The use of mechanically switched attenuators ensures broad operating bandwidth and freedom from non-linear behavior that might degrade the signals being measured.

The attenuator can be used for back-to-back testing of RF products, allowing the signal levels to be adjusted to quantify the path loss that can be inserted before the communication efficiency degrades, providing a quick indication of receiver sensitivity.

The use of a PXI solution for variable attenuation minimizes the need for components and cables located outside the PXI chassis, saving time and development costs for the systems integrator.

The design allows the user to change the front panel connectors quickly and easily in the event of damage. Attenuators can be connected in series to increase the total available attenuation.
