Introduction
Manual Conventions
The conventions used in this manual to illustrate instrument keys and display
information are as follows:
This is an example of a hardkey. They are located below the display in the handle of
ProBER 2 and give access to different sets of instrument settings. The key shown
here accesses the main menu of the instrument and returns the cursor to the top of
the display.
This is an example of a softkey. They are located immediately below the display and
are used to select instrument settings. The functions associated with softkeys are
shown in the display directly above the softkey and change as you move the display
cursor from one instrument setting to another.
These are the cursor control keys. They are located in the handle and are used to
move the display cursor from one instrument setting to another.

Introduction
ProBER 2 - an overview
2 Mb/s BER and signal quality measurements in a hand-held tester
The ProBER 2 test set provides a powerful hand-held solution for testing 2 Mb/s
and 64 kb/s digital circuits. It offers extensive BER test functions plus a unique
range of signal quality measurements (pulse mask, jitter, level and frequency). This
unmatched (in a hand-held) test capability, combined with the intuitive operation of
ProBER 2, simplifies installation and maintenance testing for faster problem
resolution.
A range of signal quality measurements for faster problem resolution
Save time by quickly identifying signal quality problems before running long-term
error measurements or during trouble-shooting. With a single keystroke, ProBER 2
rapidly identifies any frequency, level, pulse shape or jitter problem on a 2 Mb/s
signal.
Measurement summary
ProBER 2 supports comprehensive functional and parametric capability providing
the ability to fully evaluate 2 Mb/s, n x 64 kb/s and 64 kb/s co-directional circuits.

1Getting Started
This chapter is intended to give first-time users a quick over-
view of the main features of ProBER 2. It is a repeat of the
information in the Getting Started booklet, E7580-90019.
Much of the information is repeated later in this manual, but
in greater detail.
