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 and audio simultaneously
- Outputs can be independently timed
- Generates 30+ test signals
- Flash memory card for making custom test patterns
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, 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. For the ultimate in precision, the 7400 can lock to an external 10 MHz source, such as an atomic standard or GPS receiver.
The 7400 has three internal video reference generators. Gen A and Gen B each provide two configurable outputs; the first output can be either HD SDI or SD SDI, the second output can be either composite or Tri-Level Sync. Gen C provides an additional Tri-Level output. Each output set can be timed with respect to the reference to any point in the television frame. Color framing tracks the reference signal. Timing adjustments for Gen A, Gen B and Gen C outputs are configured independently. The 7400 can be configured to output 525, 625, and multiple HD standards simultaneously. Outputs from the same Gen must be selected within the same frame family.
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.
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. An ID slate with user programmable text can overlay the test pattern.
In addition to the standard suite of test patterns, users 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.
