1 Introduction to the L4400 Series LXI Instruments
This section lists important items and actions that can affect the operation of your modules.
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). |
|
|
|
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. |
|
|
|
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.
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 series instruments can be located on a benchtop or rack mounted in standard 19inch EIA rack cabinets.
Cooling and ventilation of the L4400 series instruments are through the sides of the instrument chassis. When placed on the benchtop, ensure the sides of the instrument are not directly covered or blocked.
The L4400 instruments are mounted in EIA rack cabinets using the Y1160A rack mount kit. The kit allows you to mount one or two L4400 instruments sideby- side on a sliding shelf, while occupying one EIA rack unit of space.
Rackmounting instructions are provided with the kit and are also provided here.
The contents of the Y1160A sliding shelf rack mount kit are listed in Table

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).

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.

Figure 1-4. Installing 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.

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:
•Selecting a LAN Network
•Connecting the LAN Cables
•Configuring the LAN Interface
•GPIB Configuration
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.
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.
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.
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.
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.
