iTuner Manual

1Introduction

The iTuner is an intelligent, TCP/IP capable, microwave tuner with a built in microprocessor and

command language. As such, the iTuner may be operated in one of three ways:

1) In conjunction with Focus Microwaves’ Load Pull Explorer software.

2) Independently by using the Focus Microwaves provided ActiveX control in the

programming language of choice (C++, Visual C#, VB.NET, Agilent VEE, LabView,

LabWindows, or any other platform allowing the use of ActiveX controls).

3) Independently by using a raw TCP/IP text based command interface and the

appropriate telnet client such as Microsoft HyperTerminal.

1.1 System Requirements

The iTuner can be used independently on any operating system supporting industry standard

TCP/IP communication. However, the use of iTuner with Load Pull Explorer requires Microsoft

Windows. Furthermore, calibration of the iTuner must be performed using Load Pull Explorer.

These system requirements can be summarized as follows:

Ethernet connection with appropriate RJ-45 cable(s)

TCP/IP capable operating system (Unix, Linux, Microsoft Windows, Solaris or other)

Ethernet Hub for operation of multiple iTuners

For calibration only: Focus Microwaves’ Load Pull Explorer and compatible version of

Microsoft Windows (XP or Vista)

iTuner Manual

2IP Address Configuration and Connection

An iTuner is a TCP/IP device connected over Ethernet. As such, the user needs to ensure that all

iTuners, as well as other TCP/IP devices, connected to the system have a unique IP address. This

is accomplished by connecting each individual iTuner to the system one at a time. The user

must then configure each tuner. Furthermore, the computer used must be set to a fixed IP

address. This procedure is described using the HyperTerminal TCP/IP client that is included with

Microsoft Windows (note: any telnet client may be used).

2.1 Setting the computer’s IP address

(* This step may cause other network features to stop working depending on your LAN setup

For more information see your network administrator.)

Before setting the IP address(es) of your iTuner(s), the computer’s own IP address must be set.

Note also that the windows displayed may be slightly different than those displayed here,

depending on the version of Windows.

1. Open the Windows Control Panel and choose Network Connections.

Figure 2-1

2. Right click the Local Area Connection entry and select properties

In particular if your network has DHCP enabled, your network administrator must assign your computer

a fixed IP address.

iTuner Manual

Figure 2-2

3. A screen should appear with all the network adapters installed on your computer, select the

one responsible for TCP/IP and select properties as depicted below:

Figure 2-3

4. A screen should appear indicating different network settings. Choose to specify an IP

address manually, as shown below, and enter the subnet mask of 255.0.0.0.

iTuner Manual

Figure 2-4

5. Record the IP address entered for later use.

IMPORTANT: The tuner uses a subnet mask of 255.255.0.0. Therefore the first to numbers of

the IP address of the client must match the first two numbers of the IP address of the tuner.

IMPORTANT: Computers use an IP-to-Physical address translation table used by the address

resolution protocol (ARP). After swapping tuners, or after changing the IP address of a tuner,

we strongly recommend to clear the ARP entries on the computer. From the DOS prompt, type

ARP –d *, or ARP /h for help on using the ARP command.

2.2 Single tuner TCP/IP connection

Determine the tuner’s IP address by powering up the tuner; the IP address will be shown on the

display window.

Connect the tuner via a RJ-45 crossover cable

to the computer to be used for control as shown

below.

RJ-45 crossover cable has the send and receive lines ‘crossed’ this allows the cable to be used to connect

between two Ethernet devices directly, without the use of a hub or router.

iTuner Manual

Figure 2-5: Single Tuner Configuration

Create a new TCP/IP HyperTerminal connection using the IP address of the target tuner as the

host address and port 23 as shown below.

Figure 2-6

To change the tuners IP address, connect to it via the new HyperTerminal connection and use

the IP_SET command as shown below:
