The Agilent 85029B verification kit contains a set of precision 7 mm devices, with data traceable to NIST, used to verify the calibrated performance of an Agilent 8753 measurement system. Measuring known devices, other than the calibration standards, is a convenient way of verifying that the Agilent 8753 measurement system is operating properly. The devices have precision 7 mm connectors and include a 20 dB pad, a 50 dB pad, and a mismatch attenuator. The verification process requires only an Agilent 85031B calibration kit, and an Agilent 85029B verification kit. Option 001 is intended solely for use with the Agilent 8702B lightwave component analyzer. Option 001 adds verification data that is compatible with the Agilent 8702B.
