The HP/Agilent 11613B Calibrator is a precision instrument for calibrating and verifying scalar network analyzers in the 8757 and 8756 series. It supplies a 27.778 kHz frequency source, precision attenuators, and calibration standards necessary for accurate reference plane calibration and S-parameter verification. The system includes control software that verifies and adjusts internal calibration parameters stored in nonvolatile memory, restoring measurement accuracy across the supported analyzer platform.
