Phase Matrix


Phase Matrix, Inc.—a wholly owned subsidiary of National Instruments—designs and manufactures RF and microwave test and measurement instruments.  The company was formed in 1999 when former employees of EIP Microwave (a longtime manufacturer of RF and microwave test and measurement instruments) purchased a substantial amount of EIP's assets. The company continues to support the large installed base of EIP frequency counters and its family of PXI frequency downconverters.

In 2011, Phase Matrix was acquired by National Instruments.  Popular products such as QuickSyn frequency synthesizers and extensive line of oscillator-based components were re-branded to NI Microwave Components.
