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
63 dB in 1 dB steps. Attenuator operating
time is typically just 5 ms, 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 behaviour that might
degrade the signals being measured.
