SDI7 Dual Channel SD/HD/3G SDI Video Generator module
DDS STATUS. Thi
s diagnostic displays the following:
DDS0 Phase – Indicates that the flex clock circuit is correctly aligned with
the internal f
rame pulse for output channel 1 (SIGNAL 1A and SIGNAL 1B
connectors). This readout should show Lock (locked). An Unlk (unlocked)
reading might indicate a problem with the module or mainframe.
DDS1 Phase – Indicates that the flex clock circuit is correctly aligned with
the internal frame pulse for output c hannel 2 (SIGNAL 2A and SIGNAL 2B
connectors). This readout should show Lock (locked). An Unlk (unlocked)
reading might indicate a problem with the module or mainframe.
TEMPERAT
URES. This diagnostic displays the temperature of the SDI7 module
board and FPGA.
FPGA VERSION. This diagnostic displays the current and expected FPGA
versions. If there is a discrepancy between the two, a warning appears, which
means that the FPGA firmware might need to be upgraded.
