Normal attenuator can only introduce and display an attenuation value, you need a separate power meter to measure or adjust the output power value of attenuated optical signal. Working like a combination of attenuator and power meter, OVA-50 Output Power Control mode enables direct setting of precise optical power level and can automatically stabilize output level without any interference by variations of input power.
Features:
● Attenuation range: 2.5-60dB
● Direct output power control
● Working modes
● Output power control
● Absolute/relative attenuation setting
● Program (10 preset frequently-used attenuations)
● Adjust at step of 0.05/0.10/1.00/10.00 dB
● PC control via USB
● USB power charging
● Backlight
● Over 30 hours continuous operation
● Handheld, light and easy-to-use
● CE FCC certificates
