The 1900 series consists of highperformance LCR Meters designed to perform fast, automated impedance measurements on a variety of electronic components and materials. These meters have a basic accuracy specification of 0.1% for accurate test results over a wide frequency range, from 20 Hz to 1 MHz. Besides their 15 impedance parameters, the 1900 meters are also capable of measuring dc resistance as well as monitoring the voltage or current in the device under test. The units incorporate a distinctive sequence test mode, allowing up to 6 uniquely different tests to be performed quickly on a single start command. Additionally, these meters include IEEE-488, RS-232, and handler interfaces, all standard.
The 1910 Inductance Analyzer adds bias current capability from 1mA to 1A. The addition of bias current makes the 1910 ideal for measuring inductance of power inductors under actual operating conditions.
