Keysight Technologies manufactures electronics test and measurement equipment and software. It is an innovation leader in areas such as 5G, automotive, Internet of Things, network security, and more. Although the offer was reduced from its HP/Agilent days, Keysight continues to offer a number of optical test products.
At Simbol Test Systems we have been servicing and calibrating HP, Agilent and Keysight products since our foundation in 2000. We have extensive repair knowledge of the HP/Agilent branded Tunable Laser Sources (TLS) and Optical Spectrum Analyzers (OSA). We also revive 8164A, 8163A, most of the modules that fit those mainframes and many other optical test products. Email us with a description of the problems you need solved and we'll quote.
