1900 Series Precision LCR Meter
20 Measurement Parameters
The 1900 series can measure and display any two of its 15 impedance parameters simultaneously with a basic accuracy of 0.1%. Additionally, these meters can measure the DC resistance, or display the current through or voltage across a test device ensuring the operator of the real test conditions. Wide Frequency Range The 1900 series off ers over 27,000 user- programmable test frequencies to fully characterize devices over the range of 20 Hz to 1 MHz. The 1900 series consists of high- performance LCR Meters designed to perform fast, automated imped- ance measurements on a variety of electronic components and ma- terials. These meters have a basic accuracy specifi cation 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 resis- tance as well as monitoring the volt- age or current in the device under test. The units incorporate a distinc- tive sequence test mode, allowing up to 6 uniquely diff erent tests to be performed quickly on a single start command. Additionally, these me- ters include IEEE-488, RS-232, and handler interfaces, all standard. Features:
- 20 measurement parameters
- Frequency range: 20 Hz to 1 MHz
- Basic measurement accuracy: 0.1%
- Measurement speeds up to 40/sec
- Displays voltage and current measurements
- Wide measurement range with 5-digit measurement resolution
- Four-terminal kelvin connections to maintain measurement integrity
- Programmable dc bias voltage, 0-2V
- Constant voltage (voltage leveling)
- Automatic test sequencing: up to 6 individual tests in one pass
- Menu-driven interface for user-friendly operation
- Autoranging measurements or manual hold
- Averaging measurements: up to 1000
- Interfaces: IEEE-488.2, RS-232, and Handler
- Open/Short zeroing and cable- compensation
- 14 Pass/Fail bins
- Load correction Automated Test Sequencing For increased productivity and throughput, up to six diff erent tests in sequence can be performed with a single push of the start button. Each test can have diff erent measurement parameters, test conditions, and limits. Programmable Source Impedance Measurement results can vary substantially based solely on the source impedance of the test instrument being used. To compare measurements made on other test instruments, the 1900 series can have its source impedance set at 5, 25, 50 or 100 Ω.
1910 Model
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.
1920 Model
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.
