Stanford Research SR720 LCR Meter

The SR720 LCR Meter measures major (L, C, R) as well as minor (Q, D, R) parameters of passive components with 0.05 % accuracy. The meter can perform measurements at five fixed test frequencies ranging from 0.1 to 100 kHz and adjustable amplitudes from 0.1 to 1.0 Vrms. The device accepts up to 40 Vdc external biasing if the built-in 2 Vdc is insufficient for a measurement. Included in this rental package is an SR728 BNC adapter for connecting remote fixtures and other equipment. Three binning schemes (pass/fail, overlapping, and sequential) are useful for ensuring that groups of components have the same parameter values that are listed on their specification sheet within a programmable error. Computer control is enabled through an RS-232 or GPIB connection.
