7400 Test Signal Generator and Sync Pulse Generator
- Use as Master Sync Gen or lock to
external reference or GPS - Can output SD SDI, HD SDI, composite, time code and audio simultaneously
- Outputs can be independently timed
- Generates 30+ test signals
- Flash memory card for making custom test patterns
Reliable and Easy-To-Use
The 7400 HD/SD Sync Generator/Test Signal Generator is a stable timing source that is perfect for local reference generation in broadcast, remote trucks and post. HD SDI, SD SDI, analog composite, HD Tri-Level Sync, time code, AES audio and analog audio reference outputs are generated. The 7400 can operate from an internal precision frequency reference as a stand alone Master Sync Generator or lock to a video reference or 10 MHz precision reference. Alternately, the 7400-GPS option can be used.
7400-GPS Option for the Ultimate Precision Reference
For the ultimate in precision, the 7400-GPS option can be used with the 7400 module. The purpose of this GPS option is to provide an extremely precise frequency reference. The oscillator on the 7400-GPS is more accurate than a typical internal precision standard and is equivalent in accuracy to an atomic standard. Increased frequency accuracy makes it possible to frame synchronize signals between different facilities with virtually no dropped or doubled frames. The GPS option also provides precise time of day information which can be used to drive the 7400 module’s internal timecode generators.
The 7400-GPS option seamlessly integrates into the Avenue system by plugging directly onto the 7400 module. It can be easily installed in the field. The 7400-GPS option consists of a compact, weatherproof antenna (with internal high-gain pre-amp) and a receiver submodule which mounts directly to the 7400 module. Connection from the
F-style coaxial fitting on the antenna to the appropriate BNC on the Avenue Frame can be made with customer supplied standard 75 Ohm cable. When low loss cable such as Belden 1694A is used, the antenna can be placed up to 200 feet (60 meters) from the frame. Ideally, the antenna is mounted outdoors where it has an unobstructed view of the sky.
Your Favorite Test Patterns
There are over 30 test signals including: Full and Split Field Bars at 75% and 100% with Pluge; Black; Flat Field; Pulse and Window; Ramp; Crosshatch; Safe Title; Blanking
Markers; Cosite; Checkfield, and 5 Step. The Cyclops feature adds a motion element to the selected video test signal so you can verify if a signal is live or frozen elsewhere
in the signal chain. An ID slate with user programmable text can overlay the test pattern.
Audio Generators
Up to sixteen channels of embedded tone or silence are supported. There are two stereo audio generators, each is selectable for tone frequency and whether or not there is left/right ID. The AES outputs are synchronous to the video outputs as they all share the same time base, making the 7400 a perfect fit in multi-standard facilities.
Customize Your Own Test Patterns
In addition to the standard suite of test patterns, you can create custom test patterns on a computer. Simply transfer test patterns to the included Secure Digital flash memory card using Avenue Logo software and a standard card reader, then insert the memory card into the 7400. Test patterns can include motion and an associated audio clip.
7400-EX Expando Module for Total Flexibility
If your facility seems to need every type of reference signal, the 7400 module with the 7400-EX is just what you need. Two generators provide myriad reference signals including: 12 types of HD SDI bars and black, SD SDI bars and black, composite bars and black, HD Tri-Level Sync, wordclock, AES and analog audio tone, and time code. The two generators can be independent or locked together. The control system lets you assign signal types to the output BNCs and 2 high density D connectors. The 7400-EX option can be installed in the field.
