The Web Server Diagnostic Tool
The 34980A/L4445A has a
built-in Web Server that
provides a very powerful
configuration, diagnosis, and
verification tool. All you need
is a LAN connection, Web
Browser, and the IP address.
If your computer can access
eBay.com, you can access
a 34980A or L4445A module,
from anywhere. You need NO
other software to completely
configure the 34980A/L4445A.
All module drivers exist within
the 34980A/L4445A.
The LXI instruments can be
configured for DHCP (obtain
an IP address from an external
host), AutoIP (34980A/L4445A
can assign its own IP address),
or manual IP assignment. Once
you know the IP address, you
simply enter that into the Web
Browser’s URL. Up to six Web
Browsers can be simultaneously
connected.
The figure at right shows
one of the test box
configurations.
Here are some of the key
capabilities provided in the
Web Server:
• Diagnostic tool –
troubleshooting and
wiring verification
• Visual aid in developing
external programs
• Log/capture programming
commands (SCPI)
• Learning tool to under-
stand how to program
• Passive monitoring of
test system measurements
• Switch relay count report
generation
• Create/test switch sequences
The Web Server gives you a
graphical representation of each
switch module. Switches can be
opened and closed by pointing
and clicking your mouse. Other
modules, such as Digital IO,
Analog Output, etc., are easily
and completely configurable
from the Web interface.
Having a complete and graphical
representation of every switch
and module in the 34980A/
L4445A is a powerful way to
verify wiring and troubleshoot
your system configuration. The
34945A/ L4445A Switch Driver
module Web Interface makes it
easy to setup and verify your
discrete RF/Microwave switches
and attenuators. The figure
below illustrates a partial view
of the Web Server when looking
at the configuration of the
Y1155A distribution board in
the previous section, Example #2.
Pressing Open or Close will
actuate the switches. If the
switch has position feedback,
that is reflected under Position
Indicator. Note that the example
shows a mixture of a Single
Channel (single coil drive) and
Paired Channel (double coil
drive). The single coil drive
channel is an addition to
Example #2.
