TG19CC Shibasoku Generator

The TG19CC is a generator from Shibasoku. A signal generator is a device that creates electronic signals, repeating or non-repeating, in the digital or analog domains, depending on need. Signal generators design, test, troubleshoot, and repair electronic devices across many different industries and applications.

The Shibasoku TG19CC is an all-in-one signal generator, providing for video, sound, RF and teletext signals from a single generator unit. The user-friendly control panel and unique system architecture allow users to make combined signals including Circle On/Off.

Signal sets are provided for most of the world's TV systems, including NTSC, PAL, SECAM, PAL-M, PAL-N, NTSC-4.43MHz. All output signals provide Composite video, GBR, YUV and Y/C (S-VHS). In addition to the video formats, the TG19C Series can also generate an RF output signal of 30 to 900 MHz which can be modulated with the user-selected TV system. An internal audio oscillator provides for either modulated 400 Hz or 1 kHz sound output.

Over 500 standard test signals are provided, including monoscope, color bar, stair step, and multiburst. The user may simultaneously combine waveforms to provide custom compilation signals. The TG19CC is ideal for the inspection of color-ringing, resolution, frequency response, geometry response, and linearity. Facilities are also provided for switching Burst On/Off, Color/Mono, Interlace/Non-interlace, and Aspect Ratio 4:3/16:9.

The TG19CC is one of three versions and includes teletext systems. The mono/stereo sound systems provided are those used in Japan, USA, Korea, Germany, China, UK, Scandinavia, and France. The available teletext facilities are PDC and VPS as well as TOP, FLOF, VBI, and Closed Caption. The front panel includes a control setting memory that allows up to 99 different configurations to be recalled back at high speed. An RS-232C port is also provided for remote control. The RF and Video output levels can be set to Standard or adjusted via a rotary level control. The external input signal for Video/Sound can be modulated to an RF signal (except 2-Carrier and Nicam). The Video/Sound modulation can be changed from each standard value, and can also be changed for P/S ratio.

The high quality of the TG19C Series make it ideal for R&D applications, inspection, quality control, repair workshops, and production lines.
