HP 85029B 7mm Verification Kit
Intended Uses
System Verification. Measuring the devices of this kit and comparing the results with supplied data
provides a tops-down verification of an HP 8753A/f3 with a 7 mm 50 ohm test set. The frequency range
covered by the HP 850298 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 HP
8753A/B system. These measured values are then compared with the NBS traceable data that Hewlett-
Packard supplies with each verification kit. The HP 850298 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. NBS traceable magnitude and phase data is provided with the HP 850298
verification kit at specific frequencies from 300 kHz to 6 GHz for all four S-parameters
The uncertainty limits provided with these verification devices is the worst case sum of the measure-
ment uncertainties of the factory HP 850298 production test system plus the measurement uncertain-
ties 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. 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 HP 850298 verification kit is measured at the factory in a tightly controlled environment using an
HP 8753. The test system is calibrated with special NBS-traceable standards, allowing the accuracy of
the test system to exceed that of a standard HP 8753. This system is verified daily, using a bottoms-up
procedure that quantifies individual sources of measurement error.
Refer to Table 1 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 HP 850298 allows the user to peri-
odically 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 degrada-
tion in instrument or verification kit performance.
Applicable Systems
The HP 850298 7 mm verification kit has been designed to check the performance of the fOlIOWing
systems:
l HP 8753A with HP 85046A test set
l HP 87538 with HP 85044A or 85046A test set.
l HP 87538 Option 006 with HP 85047A test set.
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 or con-
nector 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 informa-
tion, refer to the Microwave Connector Care Manual (HP part number 08510-90064) or application
note 326, Principles of Microwave Connector Care (literature number 5954-1566).
7 mm center conductor recession (without collet) must be 0.0 to 0.002 inches (0.0 to 0.051 mm).

GENERAL INFORMATION
Weight
Net: 0.9 kg (2 lb) Shipping: 1.4 kg (3 lb)
Recommended Recertification Period
Hewlett-Packard recommends that the verification kit be recertified annually; contact your local
Hewlett-Packard sales and service office for details.
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 - is supplied both on disc and hard copy.
System Verification Procedure
The system verification procedure is located in the on-site system service manual for the HP 8753A or
87538.
l In the HP 8753A Network Analyzer On-Sire System Service Manual (HP part number 08753-90022)
the system verification procedure is located behind the System Verification tab.
l In the HP 8753A/B Network Analyzer HP 8702 Lightwave Component Analyzer On-Sire System
Service Manual (HP part number 08753-90123), the system verification procedure is located behind
the On-Site Verification tab.
MAKING A COPY OF THE MASTER DATA DISC
This disc contains data files which are unique to the verification standards shipped with your HP
850298 verification kit. Hewlett-Packard recommends that you make a copy of the master data disc for
everyday use, and store the master disc in a safe place.
Making a backup disc using the HP 8753A/B is time consuming, as many files must be copied
individually. In addition, the files applicable to the HP 87538 can only be copied using an HP 87538, and
files applicable to the HP 8753A can only be copied using an HP 8753A.
A much faster way to make a backup copy is by using an HP 9000 Series 200 or 300 computer with an
HP 9122 disc drive.
7mm Verification Kit 3

Copying the Master Disc with an HP 9000 Series 200 or 300 Computer
1.
Insert a blank disc into drive 1 of the HP 9000 series 200 or 300 computer and initialize it with the
command:
INITIALIZE “:,700,1”,7
3. Write-protect the master disc and insert it into drive 0 of the HP 9000 series 200 or 300 computer.
4. Copy the files using the computer command:
COPY “:,700,0”TO “:,700,1”
Put the master in a clean safe place, away from exposure to dust, sunlight, humidity, or magnetic fields.
REPLACEABLEPARTS
The three attenuators are separately available and should be ordered by the numbers given below.
Each of these devices has a serial number and the kit has a serial number. All four serial numbers
appear on the verification disc label.

Replacing the Master Disc
The HP 850298 master disc 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 disc, so it is important to make one or more backup copies of the Master Disc.
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 Hewlett-Packard service
office for a replacement. Please specify the serial number of the verification kit, and whether or not it
has ever been recertified. If a recertification has been performed, please indicate which service office
performed it.
If Recertification Will Be Required Soon. Hewlett-Packard recommends that you have the verifica-
tion kit recertified early. A new master disc will be generated during the recertification process.
