410C Synthesized NTSC Sync/Test Generator
Maintenance and alignment instructions for Professional-Grade Video equipment
call for the use of specialized test signals, such as the Sin
2
Pulse, Modulated
12.5T Pulse, Multiburst, Modulated Staircase and others. The 410C
meets these needs and ensures both short and long term accuracy
through the use of 10-bit Digital Synthesis. Rear panel facilities include
a 14-pin remote control connector, a second video feed (isolated from
the front panel output), CW Subcarrier output (2v p-p) and three Blackburst outputs. The 410C occupies 1
3
⁄4˝ of vertical rack space and weighs
13.1 lbs., making it suitable for rack, bench or field use.

Composite Sync and CW Subcarrier Outputs.
411Genlockable NTSC Test/Sync Generator
Ideal choice for Master Sync and Test-Signal Generator for
production, post production and systems maintenance, the
411 offers the stability and precision of Digitally Synthesized
Analog signals.
A 10-bit D/A provides excellent accuracy for all test signals,
while an 8-bit D/A is used for sync blanking and related
signals. Test signals include: SMPTE and Full-Field Color
Bars; Split Field Bars with reversed bars in lower half;
Window; Pulse-Bar (2T, modulated 12.5T and bar); Dot/Crosshatch; Red and Blue rasters; White rasters at 100 and 50 IRE; 100 and 50 IRE
Multiburst; Matrix Test Pattern that includes Crosshatch, Pulse Bar, SMPTE Bars and Multiburst; 10-Step Staircase and Ramp with Modulation
On/Off or each; and a 10 and 90 APL signal with bounce On/Off control.
Also offers digital genlock with front panel fast and slow Advance and Delay fingertip control. Mode LEDs show Sync Generator status in terms
of internal reference and both Burst and Sync Lock. A dedicated SMPTE Color Bar output, featuring a 16 digit alphanumeric source identifier,
provides a convenient Color Bar/Source ID available at all times. Character selection is easily set up at front panel fingertip controls. Included
are audio tones at 400 or 1000 Hz (internally switchable) at 0 dBm (internally adjustable from -3 to +6 dBm), balanced output at XLR connec-
tor. A Master Sync Generator that offers long-term dependability, accuracy and stability, with all the test signals that an NTSC environment is
likely to need, the 411 stands out in overall value, yet uses up only one unit (1-3/4˝) of vertical rack space.
Component Video Test Signal Generator
A precision Test-Signal source for Component and Composite systems, the 425A operates in Betacam, RGB Components, Composite and Y/C.
For Component needs RGB or Y, R-Y, B-Y (3 wire) feeds are provided.
The latter is tailored to Betacam specifications. In addition, Y and
time-compressed Chroma in the CTCM or CTDM format (2
wire) may be selected. All signals are synthesized from a 10-bit
D/A to provide both precision and long-term stability.
Component test signals include those tailored for Linearity and
Transient response in Component systems, as well as a new
(patent pending) timing signal – the Shark Fin – that provides
timing measurements over a wide frequency range. Composite
Test Signals include Color Bars, 50% White and Color-Bar, Red
Raster, Pulse/Bar and Modulated and Unmodulated Staircase.
Setup is front-panel switchable to 7.5% or zero. A standard dub connector provides direct connection to Betacam systems, and the generator
accepts source selector settings from a compatible recorder that receives its drive from the dub connector.
