The HA
series attenuators are high-resolution, extended-range, programmable attenuators
ideal for testing power meters and for general test and laboratory work.The HA
attenuators have a nominal resolution of 0.01 dB and an extended attenuation
range of 100 dB. The standard operating wavelength is 1200-1700 nm.
HA
attenuators are ideal for use in such demanding applications as multichannel AM
systems and high bit-rate digital pulse code modulation (PCM) systems. Discrete
internal optical reflections are minimized to better than 60 dB, and cavity
effects are virtually eliminated. All HA attenuators are offered with high
return loss and low spectral ripple for CATV AM systems.
The inherently
linear design of these attenuators, combined with built-in calibration and
offset functions, allows the user to match the display to an optical power meter
over a wide power range. This feature is useful in tests requiring control of
the absolute optical power source for the test device. The built-in beam
blocking switch provides fast access from any attenuation setting to infinite
attenuation (> 90 dB).
