Introduction to Programming
Connecting to the Instrument and Viewing its Home Page
With the RF switch platform and 34945EXT(s) connected as shown in Figure 2-1,
connect the switch platform to the PC using one of the options shown. Note that
a LAN cross-over cable is only required for a direct connection between the
instrument and the PC, and only if the PC does not have Auto-MDIX (Gigabit
Ethernet).
Obtaining the Host Name or IP Address
In order to connect a Web browser to the instrument, the L4490A/L4491A host
name or IP address is required. The host name set at the factory has the format:
a-l449xa-yyyyy
where ‘
yyyyy
’ are the last five digits of the instrument’s serial number
.
The serial
number of the L4490A/L4491A is located on the back of the instrument.
The L4490A/L4491A IP address can be determined using ‘Keysight Connection
Expert ’ as described in the section “Adding Instruments to the Interface” in
Chapter 3.
Start the computer’s web browser and enter the host name or IP address in the
browser’s address window. The L4490A/L4491A home page should appear as
shown in Figure 4-1.
The instrument home page displays IO information, can be used to identify a
connected instrument, and contains the menu tabs for accessing other Web
pages and additional instrument functionality.

Configuration of the 34945EXT, distribution boards, and switch/attenuator
