Introduction
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.
Description
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 20 Hz 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.
Setup Storage/Recall 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.
Load Correction Substantially improves instrument accuracy by allowing the operator
to specify the value of a known standard, measure it, and apply a correction to ongoing
measurements.
Programmable Source Impedance 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.
