Agilent N7744/5A Optical Multiport Power Meter Getting Started 1 Getting Started This document helps you start using your Agilent N7744/5A Optical Multiport Power Meter. The full user and programming documentation for the Agilent N7744/5A Optical Multiport Power Meter is on the CD supplied with the instrument and on www.agilent.com. Refer to it for details on using the Optical Multiport Power Meter.
1 Getting Started Initial Inspection Inspect the shipping container for damage. If there is damage to the container or cushioning, keep them until you have checked the contents of the shipment for completeness and verified the instrument both mechanically and electrically. The Function Tests in the User’s Guide give a procedure for checking the operation of the instrument.
Getting Started 1 AC Line Power Supply Requirements Line Power Requirements The Agilent N7744/5A Optical Multiport Power Meter complies with overvoltage category II and can operate from the single-phase AC power source that supplies between 100 V and 240 V at a frequency in the range 50 to 60 Hz.The maximum power consumption is 60 VA with all options installed. Line Power Cable In accordance with international safety standards, the instrument has a three-wire power cable.
1 Getting Started WARN IN G To avoid the possibility of injury or death, you must observe the following precautions before switching on the instrument. • Insert the power cable plug only into a socket outlet provided with a protective earth contact. Do not negate this protective action by using an extension cord without a protective conductor. • Do not interrupt the protective earth connection intentionally. The AC power requirements are summarized on the rear panel of the instrument.
Getting Started 1 Operating and Storage Environment The following summarizes the operating environment ranges. In order for the Agilent N7744/5A Optical Multiport Power Meter to meet specifications, the operating environment must be within these limits. WARN IN G The Agilent N7744/5A Optical Multiport Power Meter is not designed for outdoor use. To prevent potential fire or shock hazard, do not expose the instrument to rain or other excessive moisture.
1 Getting Started Operating Position When operating the Agilent N7744/5A Optical Multiport Power Meter choose a location that provides at least 75 mm (3 inches) of clearance at the rear, and at least 25 mm (1 inch) of clearance at each side. Failure to provide adequate air clearance may result in excessive internal temperature, reducing instrument reliability. The instrument should not be operated when resting on its rear or side panels.

1 Getting Started Making Optical Connections Optical Inputs Quad Adapter Optical Connectors Figure 7 N O TE Connecting Optical Fibers Before you attach a quad-adapter or fiber, you should make sure they are clean. This is important for accurate measurements. The fibers do not contact the optical inputs (all contact with the optical inputs should be avoided). Usually the only cleaning necessary for the optical inputs is the gentle removal of dust with pressurized, dry air.
1 Getting Started Removing Optical Interfaces N O TE There are release levers on both sides of the quad-adapter for removing it from the optical inputs. release lever release lever 1 Press the release levers on both sides of the quad-adapter to release it from the front panel of the power meter. 2 You can now remove the optical connectors from the quad-adapter. N O TE Always place the dust cap on unused connector interfaces.
1 Getting Started many users at on-site and remote locations. The instrument’s application and/or your company’s IT (Information Technology) department may have guidelines that help decide the type of network (private or site) used. If a network configuration has not been determined, refer to the following considerations concerning each type. Private LAN Considerations Among the basic parameters of a private LAN network to consider are security, performance, reliability, and IP address availability.
1 Getting Started Site LAN Considerations For applications requiring access by many users or by users at distributed sites, a site LAN network is required. In addition to supporting multiple users, site LANs often offer the advantage of being maintained by IT departments. When using a site LAN, consult your IT department regarding LAN configuration and security issues.
1 Getting Started To Site LAN Standard LAN cable PC LAN enabled instrument Ethernet Hub Switch/Router Router/Switch Connection To Site LAN PC Standard LAN cables LAN enabled instruments Figure 9 Typical Site LAN Network Connections. On site networks, the Agilent N7744/5A and the computer are connected directly to site LAN ports, or are connected to the site LAN through a switch. In each site network configuration, standard LAN cables are used.
1 Getting Started USB Interface Before connecting the instrument over USB, install the Agilent I/O Libraries Suite, which is included on a CD with the instrument. N O TE The power meter is a USB device, with a mini-USB connector. Powering Up the Instrument When you switch on the power meter, the LEDs on the front panel show the various stages of booting.
1 Getting Started Connecting over USB 1 If it is not already running, start the Agilent Connection Expert software. 2 Attach the instrument to the USB. The first time you attach an Agilent N7744A or Agilent N7745A Optical Multiport Power Meter, follow the instructions on the screen to select the driver for this instrument. When the instrument is connected, it is shown in the list.
Getting Started 1 Finding the IP Address of an instrument 1 Connect to the instrument over USB. 2 Select the instrument in the list. 3 Click on “Send commands to this instrument”. The default command is the *IDN? query. 4 Enter the command :SYSTem:COMMunicate:ETHernet:IPADdress:CURRent? then click on [Send & Read]. The instrument returns its current IP sddress.
1 Getting Started Connecting over LAN 1 Make sure the instrument is connected to the LAN, and that the LAN LED on the front panel is green. See “LAN Interface" on page 17 for more information to connecting over LAN. 2 If it is not already running, start the Agilent Connection Expert software. 3 Select “LAN (TCPIP0)” in the list. 4 Click on “Add an instrument” in the Task Guide. 5 Wait for the scan to finish.
Getting Started 1 6 Select the instrument in the list. 7 Select the instrument in the list to see the associated tasks (in the Task Guide on the left) and information (on the right).
1 Getting Started Click on [Instrument Web Interface] to control the instrument directly. If it is not already installed, you will need to install a Java run-time engine to use this page. Basic configuration and functionality are available from this web page. More advanced functionality is available through programming with SCPI commands (described in the Programming Guide available on the CD supplied with the instrument or from www.agilent.com), or using the VXI plug&play Driver version 4.1.
Getting Started 1 Claims and Repackaging If physical damage is evident or if the instrument does not meet specification when received, notify the carrier and the nearest Agilent Technologies Sales/Service Office. The Agilent Technologies Sales/Service Office will arrange for repair or replacement of the unit without waiting for settlement of the claim against the carrier.
