HP 37718A
Communications Performance Analyzer
OmniBER 718 (37718A) communications performance analyzer offers a one
box field portable multi-rate BER and jitter tester up to 2.5Gb/s (STM-16/OC-48)
for installation, maintenance, commissioning, system verification and
manufacture of SDH/SONET/ATM transport networks and network equipment.
New capability now shipping in 2000
- ATM test capability up to 2.5Gb/s
- ITU-T O.172 jitter compliance
- Jitter generation and measurement at 1.5, 45 and 52 Mb/s
- User definable jitter masks
- Synchronous-only configurations (no PDH/T-carrier interfaces required)
- E1 mapped into DS3
-
Smartsetup
Not only is the OmniBER 718 rugged and portable, its
easy-to-use Smartsetup and Smart Tests simplify the
installation and maintenance of SDH and SONET networks.
The OmniBER 718 lets you start testing with just two
key presses! With the tester connected to any signal, simply press
the Smart Test key on the front panel, select Smartsetup
and the autodiscover wizard identifies the line rate and payload
structure of the input signal. For SDH or SONET signals, the OmniBER
718 also automatically displays all of the J1 trace identifiers, that
is 16 J1 identifiers in STM-16 or 48 J1 identifiers in OC-48. Once
the signal structure has been identified it's a simple process to
select a channel of interest and to explore further into the payload.
Smart Tests
Simply pressing the front panel Smart Test key
offers a simple shortcut to the extensive capabilities within the
OmniBER 718. The Smart Tests are grouped together in functional
blocks so you don't need an instrument expert to get tests up and
running effectively. Test capability that is accessed with only a
few key presses include:
-
ATM Tests - Setup ATM payloads and Conduct ATM Tests
-
Protection Switch Time Measurement
-
Auto Jitter Transfer
-
Auto Jitter Tolerance
-
Jitter Measurement
-
Optical Power Measurement
Concatenated Payloads
OmniBER 718 provides concatenated payload testing at
all levels of an SDH or SONET signal. Concatenated payloads are vital
for the rapid testing of high bandwidth paths before they are brought
into service. Concatenated payloads are also the recommended worse-case
signal for performing jitter tests.
Remote control for manufacturing applications
OmniBER 718 is shipped with a set of universal instrument
drivers (UID's). UID's provide a suite of graphical function panels
which make programming the OmniBER 718 easy and fast. There is no
need to know about SCPI commands - the commands are generated automatically
by setting switches on a graphical function panel. UID's are supported
in the following environments:
-
LabVIEW
-
LabWindows/CVI
-
HP VEE
-
Visual Basic
-
C/C++
and on the following operating systems:
-
Windows 95
-
Windows NT
-
HP-UX
-
Sun Solaris

Remote control for remote in-service monitoring
The Distributed network analyzer software (E4540A)
lets you control the OmniBER 718 remotely, via modem or LAN, from
a PC with a mouse. Changes you make on the virtual front panel are
seen at the remote end and key presses made on the instrument are
visible on the virtual front panel on your PC. For long term testing,
dial in to a remote OmniBER 718 and download results to verify testing
is going as planned. Disconnect and reconnect anytime without interrupting
testing.
