E4990A impedance analyzer now has an enhanced measurement speed option. Low-frequency models now reportedly as fast as 120MHz E4990A model. Can use the option with the 10MHz (Opt. 010), 20MHz (Opt. 020), 30MHz (Opt. 030) or 50MHz (Opt. 050) low-frequency options. Reportedly increases measurement speed up to 10x. Analyzer has a frequency range of 20Hz to 10/20/30/50/120MHz and provides 0.045% basic accuracy, with a 40V built-in DC bias source. Equivalent circuit analysis function supports seven different multi-parameter models and enables simulation of equivalent component parameter values.
