The 1920 is a high performance LCR Meter designed to perform fast, automated impedance measurements on a variety of electronic components and materials. The instrument has a basic accuracy specification of 0.1% for accurate test results over a wide frequency range, from 20 Hz to 1 MHz. Besides 15 impedance parameters the 1920 is also capable of measuring DC resistance as well as monitoring the voltage across or current through the device under test. The unit incorporates a distinctive sequence test mode, allowing up to 6 uniquely different tests to be performed quickly on a single start command. Additionally, the 1920 includes IEEE-488, RS-232, and handler interfaces, all standard.

20 Measurement Parameters
Measure and display any two of 15 impedance parameters simultaneously, with a basic accuracy of 0.1%. Additionally the 1920 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
Over 27,000 user programmable test frequencies to fully characterize devices over the range of 20Hz to 1 MHz

Automatic Test Sequencing
For increased productivity and throughput the 1920 can perform up to six different tests in sequence with a single push of the start button. Each test can have different measurement parameters, test conditions and limits.

DC Bias Voltage
The instruments internal DC bias voltage source, programmable from 0 to 2 V in 1 mV steps, allows capacitors to be tested under real DC bias conditions.

The test operator has the ability to store and recall, from internal memory, up to 30 single test setups and 10 sequential setups (six tests in sequence). The front panel can be locked out, with password protection, to ensure that procedures are run the same way every time.

Substantially improves instrument accuracy by allowing the operator to specify the value of a known standard, measure it, and apply a correction to ongoing instruments.

The operator is able to set instrument source impedance at 5, 25, 50, or 100 ohms, an important feature when comparing measurements to those made on other testers. Measurement results can vary substantially based solely on the source impedance of the tester being used.
