Page 111 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.
Page 112 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 com- mands.
Page 113 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.
Page 114 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.
Page 115 Remote Operation Getting Started Numbers All numbers are expected to be strings of ASCII characters. Thus, when send- ing 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).
Page 116 The answer remains in the output queue until it is read or another command is issued. For example, the query OUTPUT 723;”:CALC:MARK1:X?” places the wavelength of marker 1 in the output queue. In HP BASIC, the con- troller input statement ENTER 720;Range passes the value across the bus to the controller and places it in the variable Range.

Page 119 If a bit in the Status Byte goes high, query the value of the source register to determine the cause. Command HP-IB serial poll command Returns the status byte value. Reads bit 6 as the Request Service (RQS) bit and clears the bit which clears the SRQ interrupt.
Page 120 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.
Page 121 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. For example, with HP Basic, the output queue may be read using the ENTER statement.

*ESE <numeric_value> Sets the bits in the Standard Event Enable register. The Standard Event regis- ter monitors HP-IB errors and synchronization conditions such as operation complete, request control, query error, device dependent error, execution error, command error, and power on. The parameter is rounded to an integer value and interpreted as a binary number, representing the bit values of the register.
Page 149 Status Byte. When a bit in the Status Byte goes to 1, if the correspond- ing bit in the Service Request Enable register is a 1, the instrument asserts the Service Request line on the HP-IB. *SRE? Returns the value of the Service Request Enable register.
Page 150 Remote Operation Common Commands *STB? Returns the current value of the instrument’s Status Byte. This will not change the Status Byte register. The response value is an integer, to be interpreted as a binary number, representing the bit values of the register. Performing a serial poll on the instrument also reads the Status Byte register, except that bit 6 indicates whether there is a service request that has not been serviced.

Page 268: Cleaning Connections For Accurate Measurements
Reference 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 269 When tighter alignment is required, HP instruments typically use a connector such as the Diamond HMS-10, which has concentric tolerances within a few tenths of a micron. HP then uses a special universal adapter which allow other cable types to mate with this precision connector.
Page 270 0.2 µ m. This process, plus the keyed axis, allows very precise core-to-core alignments. This connector is found on most HP lightwave instruments. The soft core, while allowing precise centering, is also the chief liability of this connector.
Page 271 Reference Cleaning Connections for Accurate Measurements Inspecting Connectors Because fiber-optic connectors are susceptible to damage that is not immedi- ately obvious to the naked eye, bad measurements can be made without the user even being aware of a connector problem. Although microscopic exami- nation and return loss measurements are the best way to ensure good connec- tions, they are not always practical.
Page 272 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.
Page 273 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.
Page 274 Reference Cleaning Connections for Accurate Measurements • Use fusion splices on the more permanent critical nodes. Choose the best con- nector possible. Replace connecting cables regularly. Frequently measure the return loss of the connector to check for degradation, and clean every connec- tor, every time.

Page 277 Cleaning an adapter The fiber-optic input and output connectors on many HP instruments employ a universal adapter such as those shown in the following picture. These adapt- ers allow you to connect the instrument to different types of fiber-optic cables.
Page 278 Reference Cleaning Connections for Accurate Measurements 3 Dry the inside of the adapter with a clean, dry foam swab. 4 Blow through the adapter using filtered, dry, compressed air. C A U T I O N Do not shake, tip, or invert compressed air canisters. This releases particles from the can into the air.
