book.book Page 2 Monday, January 31, 2000 10:34 AM Remote Operation Remote Operation Remote Operation This chapter provides information on remote programming of the HP 86140series optical spectrum analyzers. The easiest way to program the instrument is by using the VXIplug&play universal instrument drivers. The VXIplug&play universal instrument drivers allow you to develop programs using the following applications: HP VEE, LabVIEW 1, LabWindows/CVI, C, C++, and Microsoft®2 Visual Basic3.
book.book Page 3 Monday, January 31, 2000 10:34 AM Remote Operation Remote Operation Table 4-1. Front-Panel Features Indicates that the instrument is operating under HP-IB control. Indicates that the instrument has requested service from the computer. Refer to “Monitoring the Instrument” on page 4-11. Pressing this button activates the front-panel keys after a computer has had control of the instrument.
book.book Page 4 Monday, January 31, 2000 10:34 AM Remote Operation Getting Started Getting Started One of the easiest ways to learn how to write programs to control the instrument is to look at simple examples. In “Example Programs” on page 4-16, you’ll find several useful example programs. Although they are written using the HP BASIC language, you can easily convert them to the language that you are using. The HP 86140 series’ HP-IB address is configured at the factory to a value of 23.
book.book Page 5 Monday, January 31, 2000 10:34 AM Remote Operation Getting Started Remote command buffering The OSA accepts serial data via HP-IB, testing each byte. Once a complete command is received and interpreted, the HP-IB handshake is held until the command operation is completed. Once completed, the next command byte is read by the analyzer.
book.book Page 6 Monday, January 31, 2000 10:34 AM Remote Operation Getting Started Syntax notation conventions The following information applies to the common and instrument-specific commands listed in this chapter. All measurement values and parameters are sent and received as ASCII strings with the exception of the following commands. These commands send and receive floating point binary data in IEEE 488.
book.book Page 7 Monday, January 31, 2000 10:34 AM Remote Operation Getting Started SCPI command are grouped in subsytems In accordance with IEEE 488.2, the instrument’s commands are grouped into “subsystems.” Commands in each subsystem perform similar tasks. The first page of this chapter lists where each subsystem is documented. Sending a command It’s easy to send a command to the instrument.
book.book Page 8 Monday, January 31, 2000 10:34 AM Remote Operation Getting Started Combine commands from different subsystems You can send commands and program queries from different subsystems on the same line; simply precede the new subsystem by a semicolon followed by a colon. In the following example, the colon and semicolon pair before CALC allows you to send a command from another subsystem.
book.book Page 9 Monday, January 31, 2000 10:34 AM Remote Operation Getting Started Numbers All numbers are expected to be strings of ASCII characters. Thus, when sending the number 9, you would send a byte representing the ASCII code for the character “9” (which is 57). A three-digit number like 102 would take up three bytes (ASCII codes 49, 48, and 50). This is taken care of automatically when you include the entire instruction in a string. Several representations of a number are possible.
book.book Page 10 Monday, January 31, 2000 10:34 AM Remote Operation Getting Started Querying data Data is requested from the instrument using a query. Queries can be used to find out how the instrument is currently configured. They are also used to obtain results of measurements made by the instrument, with the query actually activating the measurement. String responses are returned as uppercase letters. Queries usually take the form of a command followed by a question mark (?).
book.book Page 11 Monday, January 31, 2000 10:34 AM Remote Operation Monitoring the Instrument Monitoring the Instrument Your programs can monitor the HP 86140 series for its operating status, including querying execution or command errors and determining whether or not measurements have been completed. Several status registers and queues are provided to accomplish these tasks as shown in Figure 4-1 on page 4-12.
book.book Page 12 Monday, January 31, 2000 10:34 AM Remote Operation Monitoring the Instrument Figure 4-1.
book.book Page 13 Monday, January 31, 2000 10:34 AM Remote Operation Monitoring the Instrument The STATus:PRESet command clears all event registers and sets all bits in the event enable registers. Use the *CLS common command to clear all event registers and all queues except the output queue. If *CLS is sent immediately following a program message terminator, the output queue is also cleared. In addition, the request for the *OPC bit is also cleared.
book.book Page 14 Monday, January 31, 2000 10:34 AM Remote Operation Monitoring the Instrument Operation Status Structure Contains bits that report on the instrument’s normal operation. Additional transition filters give you the ability to select the logic transitions which set the event register bits. For example, you can define the Measuring bit of the Operation Status Structure to be set when a status line transitions from false to true. This is a positive transition.
book.book Page 15 Monday, January 31, 2000 10:34 AM Remote Operation Monitoring the Instrument Output Queue The output queue stores the instrument responses that are generated by certain commands and queries that you send to the instrument. The output queue generates the Message Available Summary bit when the output queue contains one or more bytes. This summary bit sets the MAV bit (bit 4) in the Status Byte. The method used to read the output queue depends upon the programming language and environment.
book.book Page 16 Monday, January 31, 2000 10:34 AM Remote Operation Example Programs Example Programs These programs are provided to give you examples of using HP 86140 series remote programming commands in typical applications. They are not meant to teach general programming techniques or provide ready-to-use solutions. They should allow you to see how measurements are performed and how to return data to the computer. The programs are written in HP BASIC for Windows.

Damage to the connectors on calibration and verification devices, test ports, cables, and other devices can increase downtime and expense.
book.book Page 11 Monday, January 31, 2000 10:34 AM Reference Cleaning Connections for Accurate Measurements Choosing the Right Connector A critical, but often overlooked, factor in making a good lightwave measurement is the selection and care of the fiber-optic connector. The differences in connector types are mainly in the mechanical assembly that holds the ferrule in position against another identical ferrule. Connectors also vary in the polish, curve, and concentricity of the core within the cladding.

book.book Page 13 Monday, January 31, 2000 10:34 AM Reference Cleaning Connections for Accurate Measurements Inspecting Connectors Because fiber-optic connectors are susceptible to damage that is not immediately obvious to the naked eye, bad measurements can be made without the user even being aware of a connector problem. Although microscopic examination and return loss measurements are the best way to ensure good connections, they are not always practical.
book.book Page 14 Monday, January 31, 2000 10:34 AM Reference Cleaning Connections for Accurate Measurements Figure 6-4. A dirty endface from poor cleaning Repeated connections made without removing loose particles, or using improper cleaning tools can lead to physical damage of the glass fiber endface, as shown in Figure 6-4. When severe, the damage on one connector end can be transferred to another good connector that comes in contact with it. Figure 6-5.
book.book Page 15 Monday, January 31, 2000 10:34 AM Reference Cleaning Connections for Accurate Measurements Guidelines Use the following guidelines to achieve the best possible performance when making measurements on a fiber-optic system: • Keep connectors covered when not in use. • Use dry connections whenever possible. • Never use metal or sharp objects to clean the connector and never scrape the connector. • Avoid matching gel and oils.
book.book Page 16 Monday, January 31, 2000 10:34 AM Reference Cleaning Connections for Accurate Measurements • Use fusion splices on the more permanent critical nodes. Choose the best connector possible. Replace connecting cables regularly. Frequently measure the return loss of the connector to check for degradation, and clean every connector, every time. All connectors should be treated like the high-quality lens of a good camera.
book.book Page 17 Monday, January 31, 2000 10:34 AM Reference Cleaning Connections for Accurate Measurements Visual inspection of fiber ends Visual inspection of fiber ends can be helpful. Contamination or imperfections on the cable end can be detected, as well as cracks or chips in the fiber itself. Use a microscope with 100× to 200× magnification to inspect the entire end face for contamination, raised metal, or dents in the metal as well as any other imperfections.
