RLC Measuring Instrument

Informatie

The 1659 RLC Digibridge is a microprocessor- controlled, automatic, programmable RLC measuring instrument that provides accurate measurement, convenience, speed, and reliability at low cost. Limit comparison, binning, and internal bias are provided; four test frequencies are available for selection. With an Interface option, the Digibridge tester can communicate with other equipment and respond to remote control. The verstaile, built--in test fixture, lighted keyboard, and informative display panel makes the Digibridge tester 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 and 4 full digits for D and Q. The basic accuracy is 0.1 %. 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 account for any change of test--fixture 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 (supplied), receives any common component part (axial-lead or radiallead), 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 1659 (which has a built--in test fixture, but requires extension typically for bulky components or parts in an automatic handler). Limit comparisons facilitate sorting into 8 GO and 2 NO-GO bins. Selectable test conditions include: 4 Test frequencies (100 Hz, 120 Hz, 1kHz, and 10 kHz) Measurement speeds up to 8 per second. Measurement routine with averaging of 10 measurements. Displays: measured values, GO/NO-GO, binning. Automatic output of value, bin number, via IEEE-488 bus when this option is used. sliding a switch to connect an external Voltage Source (up to 60 V). The IEEE/Handler option 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 para 2.8, in Section 2.) A separate connector also interfaces with component handling and sorting equipment. 1.2 GENERAL DESCRIPTION 1.2.1 1659 RLC 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 1659 instrument stands on a table or bench top. 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 removable power cord and the convenient linevoltage switch. Safety is enhanced by the fused, isolating power transformer and the 3-wire connection. 1.2.2 Interface Options The IEEE/Handler Interface option adds I/O capabilities to the instrument, enabling it to control and respond to parts handling/sorting equipment. Also (via separate connector) either option can be connected in a measurement system using the IEEE-488 bus. Either "talker/listener" or "talker only" roles can be performed by the Digibridge, by switch selection
