Introduction to Option 100 and E2625A
Telecommunications Mask Template Kit
The Infiniium Oscilloscopes Option 100 Telecommunications Mask
Template Kit includes the materials necessary for you to verify that your
instrument waveforms comply with industry standards. Option 100
provides a quick method for you to certify waveform integrity during
early development and later during manufacturing tests.
This manual helps you use the standard masks supplied with Option 100.
It shows you how to load standard waveform masks into Infiniium
Oscilloscopes and use them to test the compliance of your waveforms.
All of the standard masks supplied are shown in Chapter 3.
Adding Option 100 to an existing Infiniium Oscilloscope
The Option 100 Telecommunications Mask Template Kit is orderable as
E2625A for customers who already have an Infiniium Oscilloscope.
Adding E2625A to any Infiniium Oscilloscope requires that you upgrade
the Infiniium application software to Version A.03.00 or later.

Things to know
Things to know
If you are adding the Mask Test capability to an Infiniium Oscilloscope,
make sure that the system software is upgraded to Version A.03.00 or
later.
After installing a new version of system software, you should recalibrate
the oscilloscope. Calibrating the oscilloscope is explained in Chapter 2.
Standard masks supplied are shown in Chapter 3, including file names
and templates.
What not to do
You should not use the Mask Test master disk for daily use. Instead, you
should use a copy of the master disk, as described in Chapter 2.
