Agilent / HP 85029B

The 85029B 7-mm verification kit has been designed to check the performance of 85044A, 85046A, 85047A, 8753, or 8720D and its test sets.

The frequency range covered by the Agilent 85029B verification kit is 300 kHz to 6 GHz. The system must be calibrated before performing a system verification.

The 85029B kit contains three verification devices which are 7-mm 20 dB attenuator, a 7-mm 50 dB attenuator, and a 7 mm mismatch attenuator.

A tops-down verification is a procedure in which the devices in a verification kit are
measured on the 8753A/B system. These measured values are then compared with the NBS traceable data that Agilent supplies with each verification kit.

NIST traceable magnitude and phase data is provided with the 85029B verification kit at specific frequencies from 300 kHz to 6 GHz for all four S-parameters.

The uncertainty limits provided with these verification devices are the worst case sum of the measurement uncertainties of the factory 85029B production test system, plus the measurement uncertainties of the system being verified.

If the measured data for the verification devices falls within the supplied uncertainty limits, then the measurement system passes its performance verification.

The 85029B allows the user to periodically record measured data. This history data is
useful for statistical quality control of instrument performance. Also, unusual deviations from historical data can warn the operator of possible degradation in instrument or verification kit performance.

The storage case is supplied to protect the devices from damage that will degrade accuracy. Place the devices in the case immediately after use. Measured data and uncertainty limits are supplied on disc.
