The Keysight Agilent HP 71400C light wave signal analyzer combines Keysight Agilent HP's highest performance RF spectrum analyzers with a sensitive, wide-bandwidth optical-receiver for analyzing light wave communications systems and components.
Bandwidths from 100 kHz to 22 GHz and wavelength operation from 1200 to 1600 nm, the Agilent Keysight Agilent HP performance on single-mode optical fiber. The Keysight Agilent HP 71400C can achieve a displayed average noise level low enough (< 65 dBm optical) to observe and measure intensity noise and RIN produced by semiconductor lasers. Coupled with a built-in attenuator that enables lasers with up to 1 watt of power to be tested, the light wave signal analyzer provides you with outstanding measurement range.
