Operating Basics
2-4 SPG600 & SPG300 Sync Pulse Generators User Manual
Power Connector
The sync pulse generator is designed to operate from a single-phase power source
with the neutral conductor at or near earth ground. Only the line conductor is fused
for over-current protection. A protective ground connection through the grounding
conductor in the power cord is essential for safe operation.
The sync pulse generator operates from an AC line frequency of 48 to 63 Hz, over
the range of 85 to 250VAC, without the need for configuration. Refer to Appendix
A: Specifications for additional information on power and environment
requirements.
100 BASE-T
Connect to your local Ethernet network. You can control the sync pulse generator
remotely through the port. You can also upload and download signal files, logo
files, and preset files through the port.
GPI (General Purpose
Interface)
A 9-pin subminiature D-type connector used as a ground closure interface for
recalling one of the seven preset, outputting an alarm signal, and displaying an
alarm status on the LCD. Refer to Using the General Purpose Interface (GPI) on
page 3-41 for more information.
REF
Loopthrough connectors for an external reference signal. These inputs accept the
NTSC/PAL black burst signals and CW signals. Be sure to install a
75
Ω termination on the unused connector.
CH 1, CH 2, CH 3, and CH 4
Analog black or analog test signal outputs. By default, the CH 1, CH 2, and CH 3
connectors output black burst signals, and the CH 4 connector outputs an analog
test signal. Use the System menu to change the output channel configuration.
CH 5, CH 6, CH 7, and CH 8
Analog black or analog test signal outputs (SPG600 Option 02 only). By default,
the CH 5, CH 6, and CH 7 connectors output black burst signals, and the CH 8
connector outputs an analog test signal. Use the System menu to change the output
channel configuration.
SDI 1 and SDI 2
Serial digital black or serial digital test signal outputs. By default, the SDI 1
connector outputs a serial digital black signal, and the SDI 2 connector outputs a
serial digital test signal. Use the System menu to change the output channel
configuration.
WARNING. To avoid dangerous electric shock, do not connect power to the
instrument when the top cover is off. Dangerous potentials are present on the
Power circuit board.
