POWER button Powers the waveform monitor on or off.
ANALOG OUT(Pr, Pb, Y)
connectors
Provides three 75 W component signal outputs to drive a
component picture monitor. The output format is YP
b
P
r
as
SMPTE 240M/274M or SMPTE 296M. TriĆlevel sync is on Y.
AUDIO (CH A, CH B)
connectors
Provide digital audio outputs compliant with ANSI S4.40 and
SMPTEĂ276M. The audio channel output on CHA or CHB
connectors is selected in the AUDIO A or AUDIO B menu.
These outputs are available only for Option 0A, 240M/274M
format mode of Option 0C, or Interlace and Segment Frame
modes of Option 0D.
CH A and CH B connectors Provides for connection of serial digital signals which comply with
SMPTE 292M.
MONITOR connector Provides a serial digital monitor output signal from the currently
selected channel. Rise/fall times and jitter are not specified for
this output.
CRCE OUT connector Provides TTL output when CRC errors are detected. Connecting
this signal to an oscilloscope, for example, allows you to get more
detailed information on when these errors occur.
EXT REF connectors
(loop through inputs)
Provides for connection of an analog external synchronization
signal. These inputs are compensated for 75 W impedance and
require proper termination at one end of the loopĆthrough
connector or at the receiver in a monitored system.
REMOTE connector This 15Ćpin subminiature DĆtype connector provides limited
remote control functions.
