Description: AQ4303B white light source, very suitable for measuring the wavelength of the optical fiber and optical devices loss characteristics. This broadband high-stability light source, using a high-power halogen lamps, can provide continuous light or 270Hz square wave modulated light (adding the pulse modulator) in two ways. AQ4303B also added an optical filter, which can filter out the high-end optical components by switching operation Features: - High-speed, high stability output: AQ-4303B cover a bandwidth of 400 ~ 1800nm, providing a highly stable optical output power, power changes only is ± 0.05dB - 270 Hz pulsed light:. AQ-4303B uses a pulse modulator providing 270Hz square wave modulated light source, low power measurements provided for convenience only. - Can filter out high-end optical components: a simple B remote control: the switching operation can - GPI using the built-in optical filter to filter out high-end optical components, thus preventing their entry into the selected band. AQ4303B measurement system provides GPIB interface settings.
