The 40-180 Programmable Attenuator Module is available with either one or two independently programmable attenuators in a single width 3U PXI module. Each attenuator uses high reliability mechanical switches to operate binary weight attenuator pads, providing attenuation values from 0 to 63 dB in 1 dB steps. Attenuator operating time is typically just 5 ms, ensuring fast setting times.
Main product Features:
- DC to 3 GHz attenuator
- 1 dB attenuation resolution ideal for optimising signal levels in measuring systems
- Maximum attenuation 63 dB
- Single or dual version in one PXI slot
- Use of switched resistive attenuator pads ensures high linearity and true DC coupled operation
- Input and output connectors savers easily replaced if damaged
The module is ideal for conditioning the signal levels from devices under test and ensuring that other 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 attenuators 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 40-180 Programmable Attenuator Module is ideal for conditioning the output level of special to type sources, saving the systems integrator the time and effort of providing a variable output level. The use of a PXI solution for variable attenuation requirements minimizes the need for components and cables located outside the PXI chassis, saving time and development costs for systems integrators.
The input and output connectors of the attenuators can be interchanged and the design allows the user to change the front panel connectors quickly and easily in the event of damage occurring. The attenuators can be connected in series to increase the total available attenuation.
