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 h***e a nominal resolution of 0.01 dB and an extended attenuation range of 100 dB. The standard operating w***elength is 1200-1700 nm.
HA attenuators are ideal for use in such demanding applicati*** as multichannel AM systems and high bit-rate digital pulse code modulation (PCM) systems. Discrete internal optical reflecti*** are minimized to better than 60 dB, and c***ity 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 functi***, 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).
