  • Page 18: Entering Calibration Data Into An Hp 8702D

    HP 83400-series lightwave sources and receivers have calibration data which must be entered into the HP 8702. The data is supplied on a disk and printed on a label. The most accurate data is contained on the disk. The calibration data for newer lightwave sources and receivers is supplied on a DOS format- ted disk which can be read using the front-panel disk drive.

  • Page 19: To Copy The Data From The Disk

    1 Locate the DOS - formatted calibration disk provided with the source. 2 Place the disk in the HP 8702D’s front-panel disk drive. 3 Press CAL , CAL KITS & STDS , SOURCE STANDARDS , LOAD SRC DISK MENU . This will display the disk directory screen.

    Two procedures are provided in this section. The first procedure is the stan- dard method. You will most likely use it. However, if you have an HP-IB exter- nal disk drive, you can use the second procedure. For more information on calibration data, refer to “Entering Calibration Data into an HP 8702D”...

  • Page 31: Cleaning Connections For Accurate Measurements

    General Information Cleaning Connections for Accurate Measurements Cleaning Connections for Accurate Measurements Advances in measurement capabilities make connectors and connection tech- niques more important than ever. Damage to the connectors on calibration and verification devices, test ports, cables, and other devices can increase downtime and expense.
  • Page 32 Use dry connections. Dry connectors are easier to clean and to keep clean. Dry connections can be used with physically contacting connectors (for exam- ple, Diamond HMS-10/HP, FC/PC, DIN, and ST). If a dry connection has 40 dB return loss or better, making a wet connection will probably not improve, and can actually degrade, performance.
  • Page 33 General Information Cleaning Connections for Accurate Measurements Connector (or insertion) loss is one important performance characteristic of a lightwave connector. Typical values are less than 0.5 dB of loss, and sometimes as little as 0.1 dB of loss with high performance connectors. Return loss is another important factor.
  • Page 34 To test insertion loss, use an appropriate lightwave source and a compatible lightwave receiver to test insertion loss. Examples of test equipment configu- rations include the following equipment: • HP 71450B/51B/52B optical spectrum analyzers with Option 002 built-in white 2-13...
