The Agilent/Keysight 11574A is a verification kit designed for calibration and performance testing of LCR meters. This discontinued instrument provides standards and reference components to validate measurement accuracy across the operating range of four-terminal-pair LCR measurement systems.
Technical Specifications
The 11574A functions as a calibration and verification standard set, operating up to 13 MHz. It includes resistance standards, inductance standards, and open/short terminators to establish known reference points for LCR meter validation.
– Key Features
• Resistance standards for DC and AC impedance verification
• Inductance standards for frequency-dependent measurement validation
• Open and short terminator references for baseline calibration
• Operating frequency capability to 13 MHz
• High-accuracy reference values suitable for precision LCR meter certification
– Typical Applications
The 11574A serves quality assurance and metrological functions in environments requiring periodic verification of LCR measurement instruments. Calibration laboratories and manufacturing test facilities use this kit to confirm that four-terminal-pair LCR meters maintain specified accuracy throughout their service life.
– Compatibility & Integration
Designed specifically for HP four-terminal-pair LCR meters. The kit operates as a passive reference standard set requiring no external power or instrumentation beyond the LCR meter itself.
– Product Status
The 11574A is obsolete and no longer manufactured or sold by Keysight. Spare parts and support are unavailable.
