Description:
The GenRad 1693 RLC DIgibridge provides the best combination of features designed to optimize productivity in all testing environments. This bridge features highly accurate measurements of 11 impedance parameters and testing versatility through selection of a wide-range of test frequencies, speeds, and voltages. Its easy-to-read, dual display shows both primary and secondary measurement parameters.
The 1693 RLC Digibridge is controlled by a microprocessor, allowing for many automated functions including:
• testing
• parameter selection
• test frequency and voltage selection
• limit comparison
• binning
• zeroing
The automated capabilities of this meter can be further extended with the addition of an optional IEEE-488 interface, which allows for remote operation, programming, and data acquisition.
The combination of its high-accuracy, wide range of impedance parameters and test conditions, and automated functions make the 1693 Digibridge ideal for production testing, component design and evaluation, process monitoring, and dielectric measurements.
