Impedance Analysis Interface: Impedance Analyzer

PSM series accessory for LCR test

The PSM1700 and PSM1735 can provide LCR measurements in either 'passive mode', where an external shunt is used for current detection or with optional impedance measurement accessories available from N4L.

Passive mode

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

LCR Active Head and Impedance Analysis Interface

The LCR Active Head and IAI convert the PSM1700/1735 units into high performance LCR meters with true 4 wire Kelvin connections that are taken directly to the component under test without the need for external shunts. Buffering, amplification and selectable shunts provide LCR measurements over a wide frequency and impedance range.
