Product Description

Product Description

Intended Uses

System Verification

Measuring the devices of this kit and comparing the results with supplied data provides a
tops-down verification of an Agilent 8753A/B network analyzer with a 7-mm 50 ohm
test-set. 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.

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

Residual errors of the measurement system are, in part, due to the characteristics of the
calibration devices used during system calibration. You should use the same calibration kit
that will be used when calibrating the system for actual measurements. Using a different
calibration kit can cause inconsistent performance.

As an example, a user calibrates the system with a calibration kit that is in excellent
condition and the system passes the verification procedure easily. The system is then sent
to production and is calibrated using a worn or damaged calibration kit. In this case, the
residual errors of the system could fall outside the allowable uncertainty limits.

Each 85029B verification kit is measured at the factory in a tightly controlled environment
using an 8753 network analyzer. The test system is calibrated with special NIST-traceable
standards, allowing the accuracy of the test system to exceed that of a standard 8753. This
system is verified daily, using a bottoms-up procedure that quantifies individual sources of
measurement error.

Refer to Table 1 on page 3 to see which measurements are the basis for system verification.

PASS/FAIL information is displayed only for the most useful measurements, as indicated
in Table 1. However, all four S-parameters are measured. Additionally, the uncertainties
calculated for each device are included in printed form.

Statistical quality control of instrument performance

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.

Application Systems

The 85029B 7-mm verification kit has been designed to check the performance of:

• 8753, or 8720D and its test sets

• 85044A, 85046A, and 85047A

Recommended Practices

To maintain optimum performance from this verification kit, observe these simple
precautions:

• Always place the verification devices back in the protective case between uses.

• Make connections carefully to avoid misalignment, leading to inaccurate measurements
of connector damage.

• Keep the connectors free of dirt and metallic particles.

• If you must clean the connectors, use clean compressed air first. NEVER use abrasives.
When cleaning connectors, use liquid Freon exclusively and apply with a plastic swab.
For more information, refer to Principles of Microwave Connector Care Quick Reference
Card (part number 08510-90360).

Recommended Recertification Period

Agilent recommends that the verification kit be recertified annually; contact Agilent
Technologies for details (refer to “Contacting Agilent” on page 6).

What This Kit Contains

Verification devices

The kit contains precision standard devices. 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. In order to get a hardcopy, you
must order Option UK6.

Operation

System Verification Procedure

The system verification procedure is located in the on-site system service manual of your
particular instrument.

Making a Copy of the Master Data Disk

This disk contains data files which are unique to the verification standards shipped with
your 85029B verification kit. Agilent recommends that you make a copy of the master data
disk for everyday use, and store the master disk in a safe place.

Making a backup disk using the 8753 is time consuming, as many files must be copied
individually.

Replacing the Master Disk

The 85029B master disk contains unique data that applies to the individual verification
devices. No two devices have the same performance data. It is not a trivial matter to
replace a lost or damaged master disk, so it is important to make one or more backup
copies of the master disk.

If your master data disc is lost or damaged, and you have no backup copies, take one of the
following actions:

• If Recertification is not required in the near future. Contact your nearest Agilent
service office for a replacement. Please specify the serial number of the verification kit,
and if it has been recertified. If a recertification has been performed, please indicate
which service office performed it.

• If recertification will be required soon. Agilent recommends that you have the
verification kit recertified early. A new master disk will be generated during the
recertification process.
