Agilent4287A rf LCR tester Agilent 4287 a radio frequency LCR tester in the 1 MHZ ~ 3 GHZ frequency range can provide accurate, reliable and rapid measurement, to improve the production line to test the quality and productivity of electronic components.Unlike reflection measurement technology, the use of dc voltage measurement technology can in large range of impedance for precise measurement.In 4287 a high productivity, quality and reliable, suitable for radio frequency range of electronic components for testing.HP4286A measuring very fast.In addition, in the small test current (100 mu) good testing repeatability can significantly improve the productivity, because the average process is very short.System to form a simple test head cable (1 m or using extension cable is 2 m) is easy to receive (element fixtures) measured near the junction, and won't make any increase error.Built-in comparator function, high speed GPIB interface and processor interface are used to simplify and element fixtures and the combination of the PC.Enhance the comparator function can make complex bin is suitable for multiple frequency or array chip testing.
