User’s Guide 5 Preventive Maintenance “Using, Inspecting, and Cleaning RF Connectors" on page 90” “General Procedures and Techniques" on page 93 “Instrument Removal" on page 96” “Instrument Installation" on page 98 This chapter provides preventative maintenance information, which should be reviewed prior to working with the Agilent system. This information applies to all Agilent-supplied instruments in the system and the system as a whole.
5 Preventive Maintenance Using, Inspecting, and Cleaning RF Connectors Taking proper care of cables and connectors will protect your system’s ability to make accurate measurements. One of the main sources of measurement inaccuracy can be caused by improperly made connections or by dirty or damaged connectors. The condition of system connectors affects measurement accuracy and repeatability. Worn, out-of-tolerance, or dirty connectors degrade these measurement performance characteristics.
Preventive Maintenance 5 • Do not bend cables near the connectors. • If any of the cables will be flexed repeatedly, buy a back-up cable. This will allow immediate replacement and will minimize system down time. Before connecting the cables to any device: • Check all connectors for wear or dirt. • When making the connection, torque the connector to the proper value.
5 Preventive Maintenance Cleaning Procedure WA RN ING To prevent electrical shock, disconnect the module from mains before cleaning. Use a dry cloth or one slightly dampened with water to clean the external case parts. Do not attempt to clean internally. 1 Blow particulate matter from connectors using an environmentally-safe aerosol such as Aero-Duster. (This product is recommended by the United States Environmental Protection Agency and contains tetrafluoroethane.
Preventive Maintenance 5 General Procedures and Techniques This section introduces you to the various cable and connector types used in the system. Read this section before attempting to remove or install an instrument! Each connector type may have unique considerations. Always use care when working with system cables and instruments. GPIB Type Connector Figure 13 GPIB, 3.5 mm, Type-N, power sensor, and BNC connectors Agilent N8201A Performance Downconverter Synthetic Instrument Module, 3 Hz to 26.
5 Preventive Maintenance Connector Removal GPIB connectors These are removed by two captured screws, one on each end of the connector; these usually can be turned by hand. Use a flathead screwdriver if necessary. GPIB connectors often are stacked two or three deep. When you are removing multiple GPIB connectors, disconnect each connector one at a time.
Preventive Maintenance 5 • Turn the silver nut clockwise by hand until it is snug, then tighten with an 8 inch-lb torque wrench (part number 8720-1765). Bent Semirigid Cables Semirigid cables are not intended to be bent outside of the factory. An accidental bend that is slight or gradual may be straightened carefully by hand. Semirigid cables that are crimped will affect system performance and must be replaced. Do not attempt to straighten a crimped semirigid cable.

To install or reinstall an instrument in a system, use one of the following procedures. Required tools • #2 Phillips screwdriver • #2 POZIDRIV screwdriver • system installation guide Standard rack instrument To install an instrument Step Notes 1 Slide the instrument gently into the rack.
Preventive Maintenance 5 Half-Rack-Width Instrument To install the instrument in a rack Step Note 1 Make sure the system is powered off. 2 Insert the attached instruments in the same slot from which you removed them, sliding them along the support rails until they meet the rack-mount ears. • The rack-mount ears stop the instruments at 3 Replace the rack panel in front of the instruments and secure the four corner screws. • The screws are located near the corners of the correct depth.

User’s Guide 7 Glossary Auto-IP Auto-IP is a method used by a device to self select an IP address. When a device is using Auto-IP, it randomly selects an address of the form 169.254.x.x. If another device is already using that address, it selects another random address, and continues to select new addresses until it finds one that is not being used by any other instrument.
7 Glossary DNS [Domain Name Server] A domain name server allows someone to communicate with a device using the device’s hostname. When a device joins a network, it tells the domain name server its hostname and its IP address. When a hostname is used, the domain name server is asked which IP address the name corresponds to, and that address is then used to communicate with the instrument. If the IP address of the device changes, it can request that its entry in the domain name server be updated.
7 Glossary Private Network All of the devices on a private network use IP addresses that have been reserved for private use. The most common private network IP addresses are of the form 192.168.x.x and 169.254.x.x. Devices which have been assigned a private network IP address cannot generally communicate with other devices outside of their private network. Many devices can use the same IP address (for example, 192.168.1.1) as long as they each belong to different private networks.
7 Glossary The subnet mask can be used with a device’s IP address to determine the address of the subnet that the device is on. To do this, you perform a logical AND of the subnet mask and the IP address. (A logical AND combines two binary numbers into a single number. The new number contains 1s in positions where both numbers had 1s, and 0s everywhere else.) For example, if a device has an IP address of 192.168.12.34 and the subnet mask 255.255.255.0 then: 192.168.12.34 = 11000000. 10101000. 00001100.
