Impedance Analysis Interface: Impedance Analyzer

P seri accsory for LCR tt

TheP1700andP1735can provide LCR measurements in either 'pive mode', where an external shunt is used for current detection or with optional impedance measurement accsori available from N4L.

Pive mode

In this mode, an external shunt is placed in seri with the component under tt, then CH1 is used to measure the voltage across the component under tt while CH2 is used to measure the voltage across the shunt. From the voltag and their relative phase angle, the P units compute impedance and all LCR functions.

LCR Active Head and Impedance Analysis Interface

TheLCR Active Headand IAI convert theP1700/1735units into high performance LCR meters with true 4 wire Kelvin connections that are taken directly to the component under tt without the need for external shunts. Buffering, amplification and selectable shunts provide LCR measurements over a wide frequency and impedance range.
