Group: LCR Meter
Description: RLC Tester
Information:
                                    The two Digibridge(R) precision RLC testers, GR1689 and
GR1689M, are microprocessor-controlled,
automatic, programmable RLC measuring instruments that
provide high accuracy, convenience, speed,
and reliability at low cost. Limit comparison, binning, and
internal bias are provided; both test frequency
and voltage are selectable. With an interface option, each
Digibridge tester can communicate with other
equipment and respond to remote control.
The versatile, adaptable test fixture, lighted keyboard, and
informative display panel make
these Digibridge testers convenient to use. Measurement
results are clearly shown with decimal points
and units, which are automatically presented to assure
correctness. Display resolution is 5 full digits for
R, L, and C (4 full digits for D, Q, Rs with Cs, and Rp with
Cs). Notice that Rs is also known as ESR
(equivalent series resistance).
The basic accuracy is 0.02%. Long-term accuracy and
reliability are assured by the
measurement system, which makes these accurate analog
measurements over many decades of
impedance without any critical internal adjustments.
Calibration to ..ccount for any change of testfixture
parameters is semiautomatic; the operator needs to provide
only open-circuit and short-circuit
conditions in the procedure. The Digibridge tester normally
autoranges and automatically identifies the
principal measurement parameter.
The test fixture, with a pair of plug-in adaptors, receives
any common component part (axiallead
or radial-lead), so easily that insertion of the device
under test (DUT) is a one-hand operation. True
4-terminal connections are made automatically. Extender
cables are available for measurements at a
moderate distance from the instrument. They are optional for
the 1689 (which has a built-in test fixture,
but requires extension typically for bulky components or
parts in an automatic handler). They are
necessary for the 1689M, which has no built-in test fixture.
Limit comparisons facilitate sorting into 13 GO and 2 NO-GO
bins.
Programmable test conditions include:
Test frequencies from 12 Hz to 100 kHz
Test voltages from 5 mV to 1.275 V; bias (2 V)
Delay (before data acquisition) from zero to 99999 ms
Measurement speeds up to 45 per second (with 1689M) or 30
per second (with 1689)
Multi-measurement routines with automatic averaging and/or
median taking of
2 to 765 measurements.
Displays: measured values, percentages, differences,
ratios,GO/NO-GO, binning
Automatic output of value, bin number, bin summary and other
results via IEEE-488
bus
Bias can be applied to capacitors being measured, either by
programming the selection of an internal
supply (2 V) or by sliding a switch to connect an external
voltage source (up to 60 V).
A choice between two interface options provides full
"talker/listener" and "talker only" capabilities consistent
with the
standard IEEE-488 bus. (Refer to the IEEE Standard 488-1978,
Standard Digital Interface for Programmable Instrumentation. See
paragraph 2.8, in Section 2.) A separate connector also
interfaces with component handling and sorting equipment.
1.2 GENERAL DESCRIPTION
1.2.1 Basic 1689 Digibridge
Convenience is enhanced by the arrangement of test fixture
and controls on the front ledge, with all
controls for manual operation arranged on a lighted
keyboard. Above and behind them, the display panel is
inclined and recessed to
enhance visibility of digital readouts and indicators. These
indicators and those at the keyboard serve to inform and
guide the operator in
manipulating the simple controls, or to indicate that remote
control is in effect.
The 1689 instrument stands on a table or bench top. The
sturdy metal cabinet is durably finished, in keeping with
the longlife
circuitry inside. Glass-epoxy circuit boards interconnect
and support high-quality components to assure years of
dependable
performance. Although intended for bench-top use, this model
can be rack mounted, using a type of mount that slides
forward for
convenience.
Adaptability to any common ac power line is assured by the
removable power cord and the convenient line-voltage switch.
Safety is enhanced by the fused, isolating power transformer
and the 3-wire connection.
1.2.2 Basic 1689M Digibridge
The essential front-panel features of the 1689 are provided
on the vertical front of the model 1689M. These include the
keypad,
display, and the power ON/OFF button. The set of four BNC
connectors for connection to the test fixture is supplied on
the front panel, but
can be relocated to the rear if that is preferred. The
displaypanel and keyboard indicators serve to inform and
guide the operator in
manipulating the simple controls, or to indicate that remote
control is in effect.
The 1689M instrument also stands on a table or bench, where
the bail provided under its front edge can be used to tilt
it back
for operator convenience. This model goes particularly well
in a rack, with its vertical front pane] and cable
connection (from either front or
rear) to a suitable test fixture. The sturdy metal cabinet
is durably finished, in keeping with the long-life circuitry
inside. Glass-epoxy circuit
boards interconnect and support high-quality components to
assure years of dependable performance.
Adaptability to any common ac power line is assured by the
remo
able power cord and the convenient line-voltage switch.
Safety is enhanced by the fused, isolating power transformer
and the 3-wire connection.
