The Config menu allows you to configure the reference from the external input (525, 625
or 10 MHz sine wave) or the Master Frame Reference:
•
Config Ref – select the desired module reference from the external input (525,
625 or 10 MHz sine wave) or Master Ref (Frame Reference).
The presence of the reference will be reported in the adjacent window.
•
Pulse Select – set the type of pulse output desired for the AES Out 2/Wordclock
BNC on the rear of the frame. (Note that to enable a Wordclock or 6 Hz Pulse
output, jumper J3 must be set to WDCLK on the 5410 submodule. Refer to the
Installation section of this data pack for an illustration of this jumper.)
•
Make EDH Error – this function allows introduction of specific EDH errors into
the SDI output stream for.testing downstream equipment. when the 5410 option is
present It can also be used to verify that corrective action or alarms are generated
at those downstream points as needed or expected. This mode resets to No Errors
upon reset or power is cycled (setting is not stored in non-volatile memory.) Error
types are summarized as follows:
•
AP CRC Error – causes incorrect CRC for active picture to be transmitted
in EDH packet. Simulating a bit error, this should be detected as an EDH
error by downstream equipment.
•
FF CRC Error – same as AP CRC Error above except it is the Full Frame
which is transmitted incorrectly.
•
AP EDH Error – causes the AP EDH flag in the EDH packet to be set.
This simulates an error which was previously detected by upstream
equipment. The actual CRC will be correctly computed. This should be
detected downstream as an EDA error (Error Detected Already).
•
FF EDH Error – same as AP EDH Error above except the Full Frame flag
is also set.
•
AP EDA Error – causes the AP EDH flag to be set. This simulates a
stream where an error was detected by previous equipment. This error
should continue to be reported as EDA at every subsequent downstream
location.
•
FF EDA Error – same as AP EDA Error above except also sets the Full
Frame flag.
•
AES RefLvl – set the AES reference level to either -20 dB or -18 dB depending on
the audio requirement.
•
Anlg RefLvl – set the analog reference level from –10 dBu to +8 dBu for the
Analog Tone Output.
