The 41-180 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.
The 41-180 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 63dB in 1dB steps. Attenuator operating time is typically
just 5ms, ensuring fast setting times.
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.
