| LeCroy's
powerful and innovative Mask Tester instantly transforms
your digital oscilloscope into a dedicated mask-testing
device, specifically designed for manufacturing, type
approval and field testing. |
*
Easy to use: the Mask Tester takes over control
of the oscilloscope. The scope displays only the
Tester's dedicated menus, blocking unneeded control and
reducing setup errors |
The AP100 ProBus adapter provides adequate interfacing
and scaling for ANSI/DS-1 signals.
Dedicated
Mask Tester
With
the MT01 or MT02 Mask Tester, your LeCroy digital
oscilloscope becomes a powerful, dedicated mask-testing
instrument.
Power
& Innovation
Do you
ever wish your oscilloscope could isolate a pulse in
that scrambled STS-1 signal? Your wish is granted using
the Mask Tester's exclusive Finder search engine.
Capturing
and aligning certain telecom signals can be tricky. But Finder
uses pattern recognition. Pulse isolation can be
performed at all bit rates, on any random bit stream,
eliminating the need for sophisticated pattern
generators.

how the "1" pattern is cleanly isolated in
this PRBS stream.

Some
CMI encoded signals (STS-3E, STM-1E, 140 Mb/s) tolerate
a limited amount of offset (± 0.05 V) when the signal
is adjusted to the mask. The Mask Tester does this
automatically, prompting the user if the offset goes
beyond limits. And as required by the standard, the
resulting offset adjustment is propagated to both masks
("1" and "0").
Ease
of Use
The
Mask Tester's powerful features are even easier to use
thanks to another innovation: the Tester takes over
complete control of the scope. It shows only those
on-screen menus dedicated to the application, blocking
unneeded front-panel controls. This simplifies operation
and reduces operator error. The general purpose DSO is
made to "think and act" exactly like a
dedicated mask tester.
Maximum
Convenience
Twisted-pair
and 75 Ohm lines can easily be interfaced to the
oscilloscope via intelligent ProBus adapters. These
adapters provide the scope with both correct line
termination and accurate amplitude scaling. The balanced
adapters are Op-Amp based, providing ultra-wide
bandwidth, flat-frequency response, and overall low
distortion. Signal fidelity is assured.
Full
Remote-Control Support
All
Mask tester functions are available using high-level
remote-control commands. And because the functions are
specially designed and tailored to the Tester, it takes
fewer than ten commands to control all of them. This
makes ATE integration fast and painless.
