E2625A Datasheet, PDF (4/8 Pages) Agilent(Hewlett-Packard) – Communication Mask Test Kit

The E2698A Ethernet Masks provide mask templates for the
following standards:
Standard
IEEE 802.3
Mask Template
1000BASE-T (points A, B, C, D, F, H)
10BASE-T (TP_IDL)
10BASE-T (LINK)
10BASE-T (VOLT EXT)
10BASE-T (VOLT INT)
100BASE-TX (STP)
100BASE-TX (UTP)
Data Rate
250 Mb/s

Once you’ve chosen the
appropriate mask, simply
click on the Align button to
automatically perform a fast,
exhaustive search for the
optimum fit of the mask to
the test signal (some
communication standards do not
allow for any margin adjustment;
thus, the align function is not
available in all cases). This
virtually eliminates the need
for manual adjustments to your
oscilloscope. This is an especially
valuable feature for production
test applications.
Some communication standards
use the same template for testing
conformance on negative and
positive pulses. For those cases,
an option is available to simply
Invert Mask.
The length of a mask test can be
set to run until forever, run until
a defined number of waveforms
have been captured, or run for
a defined amount of time. An
option is also available that
allows you to stop acquiring after
a mask failure is detected.
Running a Mask Test
Once your mask kit is configured,
you can close the mask test setup
dialog box. Below the waveform
viewing area, you now have
controls to start and stop a mask
test. Additionally, you can see a
readout of the total number of
waveform points that failed in
each region of the mask template,
along with the total number of
waveforms captured and the total
number of failed waveforms.
Use the mouse or Infiniium’s
keyboard to add labels or notes
to your screen images, then save
them to the floppy or hard disk.
The built-in LAN interface makes
it easy to transfer these images
to network computers so you can
share or document your work.
You can also print the waveform
to local or network printers.
E2625A Communications Mask Test
Kit provides a 1.44MB floppy with the
mask templates as well as a number of
hardware connectors and adapters.
