Product features:

The optical attenuation and optical power output can be set quickly and accurately, and the optical power control stability time is less than 200 ms.

Multi-channel attenuator is set at the same time, and multiple ports are measured simultaneously, which saves a lot of measurement time;

Built-in high-precision optical power meter ensures the stability and accuracy of power monitoring;

Simple operation, intuitive graphical user interface, multi-channel data preview, test status at a glance.

Small size, compact structure, two 4-channel devices cascaded, can be identified as an 8-channel device to use.

Specification

Note: U8741 is single-channel, U8742 is dual-channel, and U8748 is 8-channel.

Principle of attenuator:

An attenuator is a circuit used to introduce a predetermined attenuation within a specified frequency range. It is generally indicated by the number of decibels introduced and the number of ohms of the characteristic impedance. Attenuators are widely used in cable TV systems to meet the level requirements of multiple ports. Such as amplifier input, output level control, branch attenuation control. Attenuators Passive attenuators and active attenuators two types. The active attenuator is combined with other thermal elements to form a variable attenuator, which is used in an amplifier for automatic gain or slope control circuits. Passive attenuators have fixed attenuators and adjustable attenuators.
