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.
