Serial Digital Monitors
The SDM-530 and SDM-550 are designed to
monitor the vital signs of your serial digital sig-
nal—whether it comes from cameras, video
servers, tape recorders, post production, digital
content creation, or format conversion. 19-inch rack mountable they can be used either stand-alone for applications
where Reclocking (Digital In/Out), Signal Conversion (Digital In/Analog Out) and signal monitoring are required, or
in conjunction with the AVM-510C to form a complete analog/digital signal monitoring and measurement system.
The SDM-550 is the same as the SDM-530 plus it adds an eye pattern output and decoded audio output.
■ They display information where you
work– on your color picture monitor,
where you naturally see it.
■ Once you set limits for signal parameters,
icons will pop up on the video monitor
notifying you of any out-of-limit condi-
tions. You will immediately be warned of
problems — like the signal level falling
below an acceptable level or gamut errors.
■
Speaking of gamut errors, there is no
more guessing about which video format
has been violated. Errors are shown if in
GBR, component, and/or composite.
■ To help locate the illegal color, the SDM
highlights the offending area on your pic-
ture monitor. This is especially useful if
you are a digital content creator whose
work will go to broadcast or video tape.
■
If you need to monitor signal quality
or audio levels, bar graphs will be dis-
played– no need to interpret wave-
forms to monitor signal strength, sig-
nal recoverability, or audio levels.
■ Intuitive front-panel buttons, on-screen
menus, and configuration memories
make setup and monitoring a snap.
■ A connector on the SDM’s rear panel
provides a ground closure alarm when
any selected parameter is in an out-of-
limit condition. You can attach the
connector to a variety of devices to
notify you.
■ Set them up to log errors to your com-
puter, log errors at scheduled intervals,
log errors that last longer than a specified
period, or report when all errors are
cleared. The log file documents your sig-
nal’s quality, and you can post-process it
for further analysis.
Magni’s serial digital monitors show you everything you need to know. No more illegal color, weak signal, or missing audio surprises. Rest
assured. If your video, audio, or ancillary data’s pulse is not up to par, Magni’s SDM will alert you. They continuously monitor the following
“live-video” parameters:
Eye pattern and decoded audio outputs are available if you need additional monitoring information. If your application requires you to measure
both serial digital 601 and analog video, Magni’s AVM-510C should be used in conjunction with the SDM. The AVM-510C adds quantitative
measurement for serial digital, component (SMPTE, EBU, GBR, beta, and MII), and composite (NTSC/PAL) parameters.
SDM-530: Serial Digital Monitor for serial digital 601 signal monitoring.
SDM-550: Serial Digital Monitor (same as the SDM-530, plus an eye pattern output and decoded audio output.
SDM-730: Serial Digital Monitoring and Measurement System (SDM-530, AVM-510C, and interconnecting cables)
SDM-750: Serial Digital Monitoring and Measurement System: (SDM-550, AVM-510C, and interconnecting cables)
Signal Strength:
Notifies you if the SDI signal falls below your threshold.
Gamut Error:
Notifies you if a gamut error occurs. PictureGuard icons show if an
error occurred in the GBR, component, or composite formats.
Signal Jitter (PLL):
Notifies you if the SDI signal has depleted your defined reserve range.
(The PLL reserve range represents the remaining alignment jitter margin
and indicates the receiver’s ability to recover the digital data.)
EDH Error:
Notifies you if the EDH error rate exceeds your threshold.
Audio:
Notifies you that one or more channels of audio is embedded in the
SDI signal. Audio levels can be displayed on the display monitor.
Ancillary Data Present:
Notifies you that ancillary data, excluding the audio and EDH, is pre-
sent in the SDI signal.
