An enhanced measurement speed option for its E4990 impedance analyser has been introduced by Keysight Technologies. With the added option, the low-frequency models of the analyser are now as fast as the flagship 120MHz E4990A model. Today’s passive component manufacturers face constant pressure to reduce cost, and speed overall test time; a difficult challenge given the realities of production.
During inspection, manufacturers may have to measure many devices in a day. Or, to accurately evaluate devices like resonators or inductors, they may have to measure many points per device. These tasks are all the more challenging when those measurements are performed in impedance at low frequency.
The new enhanced measurement speed option addresses these challenges by allowing manufacturers to realise fast sweep speeds at low frequency using the affordable E4990A impedance analyser.
They can use the option with the 10 MHz (Opt. 010), 20 MHz (Opt. 020), 30 MHz (Opt. 030) or 50 MHz (Opt. 050) low-frequency options to the E4990A analyzer to enable a measurement speed improvement that’s up to 10 times faster than what’s currently available on the market today.
The impedance analyser is designed for R&D, quality assurance, production and inspection engineers characterising and evaluating passive electronic components, semiconductor devices and materials.
It has a frequency range of 20Hz to 10/20/30/50/120MHz and provides an industry best 0.045 percent (typical) basic accuracy over a wide impedance range, with a 40V built-in DC bias source.
An equivalent circuit analysis function supports seven different multi-parameter models and enables engineers to simulate their own equivalent component parameter values.
