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 GPIB, 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 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.
