Outline

The CG-961 (NTSC) and CG-962 (PAL) are video signal generators??A??i especially suitable to the needs of the audio/visual area which requires a large-sized screen and higher resolutions. The test signal provides a total of 23 types of patterns including a monoscope pattern all of which are generated by the 8-bit digital data. Furthermore??A??i they are equipped with not only the monoscope pattern or color-bar signal??A??i but also other special patterns such as pulse & bar signal??A??ia 5-step modulation staircase signal??A??i H sweep signal and bounce signal??A??i etc. to be used to evaluate the video circuit characteristics -- ready to be used in a wide variety of applications.

Features

●Monoscope Pattern The monoscope pattern provides an horizontal resolution of 1,000 TV lines. It can be used for evaluation of a high-resolution TV monitor. ●Y/C-Separated Output supplied as standard In addition to the composite video output, S-Video output with luminance/chrominance separated terminals are also provided as standard. ●Amplitude accuracy of ± 3%, Phase accuracy of 3° Since the digital data is generated in 8 bits, it features extremely high accuracy. The resulting amplitude accuracy is maintained to within ± 3% or 10 mV, and the phase accuracy is maintained within ± 3°. ●Video noise evaluation signal The 50% D-white signal (luminance noise) or 100% chroma signal (chroma noise) are also provided for evaluation of the video noise. ●Bounce signal The bounce signal to be used for evaluation of the DC clamp is also supplied. It alternates between white and black every second. ●Enriched built-in patterns An H Sweep signal for evaluation of frequency response, and a 5-step modulated staircase wave for DG/DP measurement are also provided. The pulse & bar signal for evaluation of the quality of circuit characteristics. At the same time, two types of color-bar signals - full-field and split - are also built in. ●Setup 0% In answer to market trends, the CG-961 (NTSC) is equipped with the setup 75% design. ●RF Output As an RF output, 1 kHz audio signal is also added. The frequency can be varied from the front panel control. ●EEPROM backup EEPROM is employed for backup of the panel setting status. You don't have to worry about exhaustion of the backup battery. ●GP-IB option (Factory option) As a factory set option, the CG-961/962 can be installed the GP-IB interface, for accommodating an automated system. ●SPECIFICATIONS SPECIFICATIONS Model CG-961 CG-962 Patterns Pattern type Monoscope Horizontal resolution of 1?000 TV lines Cross & Dot Cross hatch: 20 × 16?
