1 Introduction to the L4400 Series LXI Instruments

Instrument Considerations

This section lists important items and actions that can affect the operation of your modules.

Environmental Operating Conditions

The L4400 Series LXI modules are designed to operate in a temperature range of 0 °C to +55 °C with noncondensing humidity. The maximum humidity is 80% at 40 °C or higher. Do not use in locations where conductive dust or electrolytic salt dust may be present.

The modules should be operated in an indoor environment where temperature and humidity are controlled. Condensation can pose a potential shock hazard. Condensation can occur when the modules are moved from a cold to a warm environment, or if the temperature and/or humidity of the environment changes quickly.

The following table shows maximum voltage ratings for each module. If conditions change, ensure that condensation has evaporated and the

instrument has thermally stabilized until pollution degree 1 conditions are restored before turning on power to the equipment.

NOTE

Pollution Degree 1: No pollution or only dry, non-conductive pollution

occurs. The pollution has no influence (on insulation) (IEC 61010-1

 

 

2nd Edition).

 

 

NOTE

Pollution Degree 2: Normally only non-conductive pollution occurs.

Occasionally, a temporary conductivity (leakage current between

 

 

isolated conductors) caused by condensation can be expected (IEC

 

61010-1 2nd Edition).

 

 

Electrical Operating Conditions

WARNING

To avoid electric shock, turn off the L4400 instrument and

disconnect or de-energize all field wiring to the instrument and to

 

 

the analog bus connector (if present) before removing any

 

terminal block covers.

 

 

Transients

The L4421A, L4433A, and L4437A modules are designed to safely withstand occasional transient overvoltages up to 1000 Vpeak. Typically, these transient overvoltages result from switching inductive loads or from nearby lightning strikes. The lightningcaused transient overvoltages that may occasionally occur on mains power outlets may be as high as 2500 Vpeak.

The L4445A, L4450A, L4451A, and L4452A modules are intended for only lowvoltage applications, and should not be connected to circuits that may generate or conduct large transient voltages.

High Energy Sources

These instruments are designed to handle inputs up to their rated currents or their rated powers, whichever is less. Under certain fault conditions, high energy sources could provide substantially more current or power than a module can handle. It is important to provide external current limiting, such as fuses, if the instrument inputs are connected to highenergy sources.

CAUTION

Install current limiting devices between high energy sources and

the module inputs.

The L4400 instrument(s) can be mounted between any two adjacent EIA unit indicators (Figure 1- 2). On Agilent racks, an EIA unit indicator is represented by a triangle ( !) on the rack’s front and rearfacing columns. A single EIA unit extends from the triangle indicator to the next indicator on the column (1 Unit = 44.45 mm = 1.75 in).

NOTE

It is not necessary to remove the cabinet side panels to rack mount the

L4400 instruments. The side panels can be removed, however, if additional

 

 

access to the cabinet’s vertical columns is desired.

 

 

Install the Shelf Rails

1. Select the vertical position in the rack between any two adjacent EIA unit indicators where the L4400 instrument is to be installed. Insert clipon nuts

(item 5) on the three holes between the unit indicators. Place nuts on both the left and right frontfacing columns (Figure 1- 3).

2. With the rail “channel” facing the center of the rack, connect the rail to the front facing column using a 1032 flathead screw (item 4) and the center clipon nut on the frontfacing column. Repeat for the rail on the opposite column. Ensure the rail channel faces the center of the rack.

If the rack has centerfacing columns (Figure 1- 3), insert a 1032 pan head screw through the rail opening and clip nut (perpendicular to the

frontfacing column). Repeat for the rail on the opposite column.

3.On the rack’s rearfacing columns, insert clipon nuts on the first and third holes between the EIA unit indicators that are at the same vertical position as the indicators on the frontfacing columns.

4.Attach the rear brackets to the rail ends using two 1032 pan head screws (item 3) and two 1032 nuts with lockwashers (item 6) per rail. Adjust the bracket along the rail until the bracket end aligns with (covers) the rack’s rearfacing columns. Tighten the 1032 pan head screws to firmly connect the bracket to the rail and maintain the rail length.

Connect the rail brackets to the rearfacing columns using two 1032 pan head screws per column.

Install Instruments on the Shelf

The L4400 instruments can be installed flush (even) with front edge of the shelf, recessed in 50 mm increments, or reversemounted with the front of the instrument facing the back of the rack cabinet.

1.Extend the shelf from the rack such that approximately 50% - 75% of the shelf surface is outside of the rack. (The tabs on the back of the shelf that run underneath the rail channel prevent the shelf from tipping.)

2.Determine the position of the instruments (flush, recessed, reversed). To accommodate the terminal blocks (available with some of the L4400 instruments) and to simplify cable routing, it is recommended that the instruments be mounted flush (even) with the front or back edge of the shelf.

3.Note the location of the four mounting holes on the bottom of the instrument (Figure 1- 1). Set the carrier on the shelf, and align the mounting holes with the holes on the shelf. Insert four M4x8 flat head screws (item 1) upward through the bottom of the shelf and into the carrier mounting holes.

4.Install the second L4400 instrument (if present) in the shelf area adjacent to the first instrument. If only one instrument is installed, install a filler panel on the front edge of the unused area. Insert two M4x8 flat head screws

(item 1) upward through the bottom of the shelf and into the panel.

5.Connect the instrument power cord, LAN cable, and GPIB cable if present.

6.For instruments that have accompanying terminal blocks, partially remove the instrument subassembly from the instrument (carrier) by loosening the springloaded mounting screws (Figure 1- 5). Remove the support sleeve from the terminal block. Locate and remove the flat head screws from the sleeve and remove the pan head screw from between the instrument’s D- sub connectors (Figure 1- 5). Connect the sleeve to the instrument using the flat head and pan head screws as shown. Reconnect the subassembly.

Configuring the L4400 Instruments

Instrument configuration as applied to the L4400 series of LXI instruments

involves the following:

identifying the IP address and host name (LAN programming)

(optional) setting the GPIB address

testing the communication paths (LAN and/or GPIB) to the instrument

opening the Web interface to the instrument

Each task listed above is accomplished using the Agilent Connection Expert Feature of the Agilent IO Libraries Suite.

The information included this section of the chapter is:

Configuring the LAN Interface

GPIB Configuration

Selecting a LAN Network

This user’s guide defines a private (isolated) LAN as a network in which instrument access is limited to a direct connection between the computer and the instrument, or to multiple instruments connected via a dedicated router or switch. A site (companywide) LAN is defined as a network in which instrument access is available to many users in onsite and remote locations.

The instrument’s application and/or your company’s Information Technology (IT) department may have guidelines that help decide the type (private or site) of network used. If a network configuration has not been determined, refer to the following considerations concerning each type.

Private LAN Considerations

Some of the basic parameters of a private LAN network to consider are: security, performance, reliability, and IP address availability.

L4400 User’s Guide

17

2 Software Installation and Configuration

Security: a private network generally involves direct connections between the computer and the instruments, and may include switches and routers. Access to the instrument is limited to users connected directly to the private network, as opposed to users on a site network that could locate and access the instrument from any location - possibly disrupting tests in progress. Code generation for test systems on a private network is often simplified as protection against unauthorized users may not be required.

Performance: test systems where large amounts of data are transferred usually have faster throughput on a private network. On a site network, heavy and unpredictable LAN traffic (lots of data) affects each instrument (node) on the network. The impact on a test system is that repeatability is difficult to achieve as latencies are difficult to account for.

Reliability: private networks are fundamentally more reliable than site networks as they host fewer users and are less complex than site networks.

Private networks are isolated from conditions that could bring down (crash) a site network.

IP Address Availability: Every instrument (node) on a LAN (private or site) has an IP (Internet Protocol) address. Due to the expanding use of the internet, the number of site network IP addresses available is limited. By using a router with Dynamic Host Configuration Protocol (DHCP) capability on a private network, the router can assign an IP address to each instrument thus creating a subnetwork (subnet) that does not consume site IP addresses.

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 all LAN configuration and security issues.

Connecting the LAN Cables

LAN cables are connected to the LAN terminal on the instrument, the computer, and to the router or switch if they are part of your network.

When making a direct connection between the L4400 instrument and the PC, use the yellow LAN crossover cable provided with the instrument. Note, if your computer supports AutoMDIX or contains a LAN card with gigabit data transfer rates, the (yellow) crossover cable is not required. A standard LAN cable can be used instead. For private LAN networks that include a switch or router, use standard LAN cables for network connections. Do not use the crossover cable.

Once the LAN cables are connected, you can turn on the L4400 instrument(s).

On site networks, the L4400 instruments 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.

Once all LAN cables are connected, turn on the L4400A instrument.

IP Addresses and Host Names

Dynamic Host Configuration Protocol (DHCP) and Automatic IP are enabled on each L4400 series instrument shipped from Agilent. This allows the instrument to automatically obtain an address on the network. If there is a DHCP server on the network, the server will assign the address to the instrument.

If there is not a DHCP server on the network, the L4400 instrument will automatically determine an address to use. The address will be in the range of

169.254.xxx.xxx. If available, the instrument will try to acquire its default setting of 169.254.44.88.
