Precision 1 MHz LCR Meter

  • Product No:QUADTECH 1900 Series
  • Manufacturer:IET LABS, Inc. 

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 1920 Precision LCR Meter adds bias voltage capability from 1mV to 2V. The bias voltage feature is used for testing capacitors or providing reverse bias for testing junction capacitance of diodes and similar components.
