Precision LCR Meters

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 offers 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 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 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 different 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 different tests in sequence can

be performed with a single push of the

start button. Each test can have different

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.
