QUADTECH’S Model 1715 LCR Digibridge component tester, available from Power Parameters , is suitable for the production testing of inductive, capacitive and resistive components.

It can be integrated into automated test environments with features including an RS232 interface and optional IEEE 488 and handler interface. Measurement speed is selectable between 25 measurements/sec, 8 measurements/sec and 2 measurements/sec.

Test frequency is selectable from 100Hz, 120Hz, 1kHz and 10kHz with measurement initiated by internal, external or manual trigger and trigger delay variable between 0 and 9999 ms.

Source impedance is automatically selected depending on the device-under-test, from 25Ω, 100Ω, 1000Ω, 10 kΩ or 100kΩ. Components can be defined through 11 parameters (series/parallel L, C and R, dissipation factor D, quality factor Q, impedance modulus Z, series reactance X and phase angle.

The Quadtech 1715 is provided with comparators permitting binning on three levels: primary nominal, primary Hi/Lo limits in %-age terms and secondary Hi/Lo value limits. The results are formatted by value, deviation, %-age deviation, and bin number. Set-up parameters are stored and are automatically recalled on instrument power-up.
