Recording the Components Serial Numbers

The N9911X Economical Waveguide Components are individually serialized (serial numbers are labeled onto the body of each component). Record these serial numbers in the appropriate table. Recording the serial numbers will prevent confusion with similar components.

The N9911X calibration components are manufactured by Flann Microwave. Each component is imprinted with a Flann logo, part ID number, and serial number. To determine the Keysight option number for a component, use the cross-references in the following tables.

General Information

Preventive Maintenance

The best techniques for maintaining the integrity of the components include:

• routine visual inspection

• routine cleaning

• proper connection techniques

All of these are described in Chapter 3. Failure to detect and remove dirt or metallic particles on a mating plane surface can degrade repeatability and accuracy and can damage any component mated to it. Improper connections resulting from poor connection techniques, can also damage these components.

When to Calibrate the Analyzer

An analyzer calibration remains valid as long as the changes in the systematic error are insignificant. This means that changes to the uncorrected leakages (directivity and isolation), mismatches (source match and load match), and frequency response of the system are small (<10%) relative to accuracy specifications.

Change in the environment (especially temperature) between calibration and measurement is the major cause in calibration accuracy degradation. The major effect is a change in the physical length of external and internal cables. Other important causes are dirty and damaged test port connectors and calibration standards. If the connectors become dirty or damaged, measurement repeatability and accuracy is affected. Fortunately, it is relatively easy to evaluate the general validity of the calibration. To test repeatability, remeasure one of the calibration standards. If you can not obtain repeatable measurements from your calibration standards, maintenance needs to be performed on the test port connectors, cables and calibration standards. Also, maintain at least one sample of the device under test or some known device as your reference device.

How to Calibrate the Analyzer

Your analyzer’s calibration user interface prompts you through each step in a 1-port or a 2-port calibration procedure. For detailed information on using your analyzer, refer to the appropriate user guide. See “Where

to Look for More Information” on page 4-3.

Temperature—What to Watch Out For

Changes in temperature can affect electrical characteristics. Therefore, the operating temperature is a critical factor in performance. During a measurement calibration, the temperature of the calibration components must be stable and within the range shown in

Tab le 2- 1.

IMPORTANT Avoid unnecessary handling of the components during calibration because your fingers act

as a heat source and may increase the temperature of the component.

Use, Maintenance, and Care of the Components

Electrostatic Discharge

Protection against electrostatic discharge (ESD) is essential while connecting, inspecting, or cleaning connectors attached to a static-sensitive circuit (such as those found in test sets).

Static electricity can build up on your body and can easily damage sensitive internal circuit elements when discharged. Static discharges too small to be felt can cause permanent damage. Devices such as calibration components and devices under test (DUT), can also carry an electrostatic charge. To prevent damage to the test set, components, and devices:

• always wear a grounded wrist strap having a 1 MW resistor in series with it when handling components and devices or when making connections to the test set.

• always use a grounded antistatic mat in front of your test equipment.

• always wear a heel strap when working in an area with a conductive floor. If you are uncertain about the conductivity of your floor, wear a heel strap.

• always ground yourself before you clean, inspect, or make a connection to a static-sensitive device or test port. You can, for example, grasp the grounded outer shell of the test port or cable connector briefly.

• always ground the center conductor of a test cable before making a connection to the analyzer test port or other static-sensitive device. This can be done as follows:

1. Connect a short to one end of the cable to short the center conductor to the outer conductor.

2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.

3. Connect the other end of the cable to the test port.

• Remove the short from the cable.

Figure 3-1 shows a typical ESD protection setup using a grounded mat and wrist strap.
