GenRad 1693 Precision LCR Meter (RLC Digibridge)

The GenRad 1693 LCR Meter Bridge gives you the best combination of features, in an LCR meter, to meet your most demanding testing requirements. It’s a versatile, flexible instrument with a full range of programmable test frequencies, speeds, and voltages. An easy to understand display show both primary and secondary measurement parameters. The Digibridge is an excellent choice for metrology applications requiring accurate and repeatable measurements. The 1693 is also widely used in production testing, incoming inspection, component design and evaluation, process monitoring or dielectric measurement applications.

The 1693 Precision Impedance Bridge is a sophisticated, patented microprocessor controlled tester that brings new levels of flexibility, simplicity and accuracy to RLC measurement. It’s testing automation at its best with a range of programmable test frequencies and test voltages, as well as automatic limit comparison, automatic parameter selection, remote programmability, automatic binning, and automatic zeroing.

The 1693 Precision Impedance Bridge provides a powerful combination of features designed to maximize productivity in all testing environments.

• 0.02% Accuracy for RLC measurements and 0.0001 Accuracy for DQ measurements.
• Programmable test frequencies from 12Hz to 200kHz for maximum testing versatility.
• Programmable test voltages from 5mV to 1.275V permits testing at exact manufacturer- specified voltage levels.
• Full range keyboard-selectable test speeds: Variable up to 19 measurements per second
• Two selectable measurement modes: Continuous and Triggered with averaging available in each ensures stable repeatable measurements
• Optional IEEE-488.2 Interface enable remote programming
• Wide choice of measurement parameters allow you to work with familiar units.
• A full, five-digit LED display for RLC measurements and a four-digit readout for D and Q testing, simultaneously display both test results for each measurement, automatically.
• Guarded Kelvin measurement techniques protect measurement integrity.
• Automatic self-test and diagnostic check maintain reliable, error-free operation.

GenRad 1693 vs. 1689M
The 1693 and 1689M Impedance Bridges are very similar instruments. However, the 1693 offers 2 major advantages over the 1689M.
1. Max Frequency of 200 kHz: The 1693 has a max frequency of 200 kHz, while the 1689M has a max frequency of 100 kHz
2. 11 Impedance Parameters. In addition to the 1689M measurement parameters of R/Q, L/Q, C/R, C/D (series or parallel), The 1693 can also measure R/X (series),G/B (parallel), Z/Angle or Y/Angle

GenRad 1693 Impedance Bridge Additional Uses

• Impedance measurements (inductance, capacitance, and resistance) to characterize the performance of a variety of electrical components and materials.
• To test resistors, capacitors, inductors or any type of passive component
• Testing sensors

GPIB/IEEE Interfaces on the Digibridge Series
IET has an excellent application note on the difference between the new style 1689-9640 GPIB Interface Card and the older style 1658-9620 1689-9620 or 1689-9630 ieee interface cards. This also covers communication with both cards via NI Max. Understanding IEEE/GPIB Interface Cards on the Digibridge Line of RLC Meters
