The accretion of bandwidth of data center network becomes even more important to the applied demand of much territory. Pure raise speed of yuan of parts of an apparatus to cannot have satisfied afore-mentioned requirement, because this PAM-4 technology regards ordinary mail of a kind of many phone as your technology emerge as the times require, the data that can promote high speed number communica

Measure basicallyUse number oscillograph can carry out extensive measurement to weaveform. Metrical range and complex degree depend on the functional collect of oscillograph. Graph the 22 blank that those who show is oscillograph of Keysight 8000 series show. The measurement that notices screen is the leftest and listed pushbutton / icon. Can use a mouse to pull these icon weaveform to go up, meas

Alterable smooth attenuator is a kind of important smooth passive in fiber-optic communication parts of an apparatus, the real time that will realize pair of signal through transmitting smooth power damply is controlled. Say simply, in smooth module, fine attenuator can reduce use light to be piled up by accident rate (BER) . Pile up by accident to achieve rate, need reduces smooth power, need to

DCA-M sampling oscillograph: The pivotal tool of digital communication systemAs the rapid development of digital communication system, also increase increasingly to test and the requirement that analyse a technology. In this domain, DCA-M sampling oscillograph serves as a kind of high-powered instrument, producing main effect. It can capture and the weaveform of signal of number of analytic h

Our commonly used instrument appearance the prevailing prices such as analyzer of spectrum analyzer, radio frequency source, network is very for instance high, if radio frequency instrument is used undeserved also can cause very big effect to the job, and maintenance value is very expensive also, so how to use ability correctly to avoid needless breakdown to appear?One, power source breakdown caus
