GETTING TO KNOW YOUR SG-6005 GENERATOR
The Kramer
SG-6005 is a broadcast quality multi-standard black burst, color bar, sync and audio generator
designed for a variety of video studio applications. It is exceptionally full featured, offering six identical black
burst outputs, a color bar output, a user programmable color matte, horizontal and vertical sync outputs, as well
as balanced and unbalanced 1 kHz, crystal stabilized audio outputs. The unit maybe genlocked to an external
video reference or it may operate as a stand-alone generator based on its high precision timing components. It
uses digital synthesis technology for signal generation and allows full SCH/Phase control, delay of output
relative to the genlock input and additional delay of the sync outputs.
The
SG-6005 may be RS-232 controlled from a PC, and firmware is easily upgraded using a computer. The
required SCH/Phase shifts and delay may be displayed on a large seven-segment LED display. The number of
outputs may be increased by using a Kramer video distribution amplifier like the
VM-1010, VM-1015, or VM-
1021, etc.
Figure 1: SG-6005 Front Panel Features
Front Panel Features Description
(1) POWER
Rocker switch to turn the machine ON or OFF. In the ON position, the switch is illuminated.
(2), (3) PAL OR NTSC
Selects the video standard of the machine. The illuminated switch indicates the selected standard. To change the
video standard, press the non-illuminated switch. The machine takes about a second to modify its internal
settings - during which time the machine will ignore the pressing of any front-panel switch, and the 7-segment
display indicates that the machine is “busy”.
(4) GENLOCK
Toggles between a “genlocked” and a “free-running” generator.
When the switch is illuminated, the machine will “genlock” to a valid reference input (REF-IN). When not
illuminated, the timing of the generator is internally generated (free-running).
To toggle between genlocked and free-running mode, press the GENLOCK switch. The machine takes about a
second to modify its internal settings - during which time the machine will ignore the pressing of any front-
panel switch, and the 7-segment display indicates that the machine is “busy”.
(5) H (BLACK BURST)
Selects / deselects the control of the generator’s horizontal synchronization relative to that of the genlock (REF-
IN) input.
When selected, this switch will flash, and the 7-segment display (12) will indicate the delay (in microseconds)
of the generator’s horizontal synchronization (relative to the genlock input). Use the “+” and “-” switches (11)
to change the delay, in steps of 37ns. Note that since the display only shows up to 3 digits, increasing and
decreasing the delay will not always change the value displayed (but it
will
always increase or decrease the
delay).
