Agilent Technologies now offers 6.5 and 14 GHz options to its E5071C ENA network analyzer. Both the 6.5 and 14 GHz options support 2- and 4-port configurations. The E5071C's new 2- or 4-port 6.5 GHz option features a frequency range of 9 kHz to 6.5 GHz without bias tees and 100 kHz to 6.5 GHz with bias tees. It is best suited for evaluation and testing of RF components in, for example, WLAN and WiMAX technology that uses carrier frequency up to 6 GHz. The new 2- or 4-port 14 GHz option features a frequency range of 300 kHz to 14 GHz with bias tees. It is best suited for 3GPP measurement requirements that call for evaluation of frequency characteristics in 3GPP components up to 13 GHz, according to the company.
