The TG700 is a multiformat, analog and digital, precision signal generation platform. Designed with the changing needs of the video industry in mind, the TG700 offers sync pulse generation and test signal generation for a wide array of analog, serial digital, and digital high-definition formats. The TG700 Multiformat Video Generator has a modular architecture that offers the flexibility to meet the single-format and growing multiformat needs of the video professional. The TG700 mainframe allows up to four of the following modules to be fitted in the mainframe.

The TG700 has a high stability reference. The AGL7 Analog Genlock Module adds the capacity to lock to a variety of signals, which makes the TG700 an ideal solution as the master house reference or slave reference for broadcast and production/post-production applications. Three black outputs are available and are selectable for HDTV tri-level or NTSC or PAL. Additionally, the AGL7 can lock to a variety of formats to include NTSC/PAL black and HDTV tri-level as well as 1, 3.58, 4.43, 5, and 10 MHz CW. When the AGL7 is configured for Stay GenLock™ mode, a momentary loss of synchronization at the genlock reference input will not cause a disturbance in the TG700’s test signal and black outputs. When the genlock signal is reapplied, the AGL7 will gradually reacquire lock, causing little disruption to devices synchronized to the TG700 reference.

The GPS7 GPS Synchronization and Time Code Module includes an integrated GPS receiver which can serve as the system timing reference. Synchronization to the GPS timing signals ensures long-term stability, and video frame alignment between independent systems. The GPS RF coaxial signal input is available with 3.3 V or 5 V DC power output for the GPS antenna enabling the user to select from a variety of GPS antennas available on the market. The GPS7 also includes a genlock input with VITC reader, enabling user-selectable configuration of the TG700 as the master reference or as a slave to another master, depending on the dynamic requirements of each production. The GPS7 module will maintain system timing by Stay GenLock™ technology even during periods of GPS signal loss or genlock signal loss. Three black outputs are available and are selectable for HDTV tri-level, NTSC, or PAL. Time code source can be selectable to the time-of-day (with user-selectable offsets) from GPS receiver, internal source, VITC on the reference input, LTC input, or to a "program time" counter for elapsed-time time code. The Daylight Savings Time (DST) adjustment could be recurring scheduled, based on calendar rules. Time code is available as VITC on black outputs (GPS7, BG7), as Ancillary Time Code (ATC) (HDVG7, HD3G7, SDI7), from four independent LTC outputs (GPS7), and as a response to time requests on a Simple Network Time Protocol (SNTP version 3.0) Server.

The ATG7 Composite Analog Test Generator supports PAL, NTSC, and NTSC No Setup. It provides one test signal output, one color bar test signal output, and two black outputs. The black outputs can independently generate H, V, black burst, and subcarrier.

The AVG7 is an Analog Video Generator for 525/625 interlace formats supporting component (Y'P'bP'r, G,B,R, Y/C), 525 Beta, and composite (PAL, NTSC, NTSC No Setup). It provides two identical component outputs, two identical Y/C and composite, or six identical composite outputs.

The AWVG7 is an Analog Wideband Video Generator that supports a variety of HD analog component formats (Y'P'bP'r or GBR). The module provides two identical component outputs with a bandwidth of 30 MHz. Up to two AWVG7 Analog Wideband Video Generators can be placed in a single TG700 mainframe.

The AG7 provides eight channels (4 AES/EBU pairs) of audio signal generation. It also provides two channels (1 AES/EBU pair) of silence as well as a 48 kHz word clock output.

The BG7 is an analog black generator with four independently selectable outputs. The BG7 Black Generator supports NTSC and PAL black burst as well as HDTV tri-level sync. With Option CB, two of the outputs can also generate various analog NTSC and PAL color bar test signals.

The DVG7 is a multiformat SD-SDI test signal generator. The DVG7 Digital Video Generator supports 525 line and 625 line serial digital video at 270 Mb/s and NTSC composite digital at 143.181818 Mb/s. The DVG7 Digital Video Generator has two identical test signal outputs. With Option BK, two additional identical serial digital black signal outputs are available.

The HDVG7 is a high-accuracy, multiformat, high-definition test signal module that provides up to two identical 1.485 Gb/s serial digital video test signal outputs in a broad variety of formats. With Option BK, two additional identical serial black signal outputs are available. Ancillary Time Code (ATC) generation is available when the GPS7 is installed in the TG700 mainframe. Up to two HDVG7 modules can be placed in a single TG700 mainframe.

The digital modules DVG7 and HDVG7 support AV timing mode and up to 16 channels of 20- or 24-bit audio sampled at 48 kHz embedded on the test signal outputs. The user can independently set frequency and level for each channel.

Full frame test and custom patterns can be generated for the AVG7, AWVG7, DVG7, and HDVG7 modules. Simple full frame patterns are available on V3.1 (or higher than V3.1) CD-ROM.

The HDLG7 is a test signal generator that provides two identical dual-link high-definition serial digital interface (HD SDI) outputs. The module supports video formats that require the use of a dual-link interface, such as 4:4:4 R'G'B' at rates up to 1080i/60 Hz or 1080p/30 Hz, or 4:2:2: Y'C'bC'r at rates up to 1080p/60 Hz. The HDLG7 supports several standard test signals, and also has the unique ability to up-convert an arbitrary single-link HD-SDI input signal to a dual-link format for the outputs. The HDLG7 also supports digital cinema 2K formats and test patterns.

The HD3G7 is a test signal generator that provides two outputs of a HD/3G-SDI video test signal. 720-line formats and 1080-line formats described in SMPTE standards are supported for both Level A and Level B mapping structures, including 4:4:4 and/or 12-bit sampling, Y'C'bC'r, R'G'B', or XYZ color space, and 2K digital cinema formats. The 2×SMPTE 292M HD-SDI format used by some 3D TV applications is also supported.

The HD3G7 can generate up to 32 channels of 24-bit 48 kHz embedded audio, with independently set frequency and amplitude for each channel. The HD3G7 also has the ability to generate other types of ancillary data, such as video payload identifier, ancillary time code, and user-defined packets.

The HD3G7 includes a wide variety of standard test signals, including SMPTE color bars, pathological test patterns, and a programmable moving zone plate pattern, and it also has the ability to up-convert an input 1.485 Gb/s HD-SDI signal to a 3G output. The HD3G7 has a clock/frame trigger output that can be used to synchronize the output with an oscilloscope, for example.

The SDI7 is a test signal generator that provides two independent channels of SD/HD/3G-SDI video test signal generation in a variety of formats with 2 outputs for test and test/black signal generation per channel (3G-SDI signal generation is optionally available). The SDI7 can generate up to 32 channels of 24-bit 48 kHz embedded audio, with independently set frequency and amplitude for each channel. The SDI7 also has the ability to generate other types of ancillary data, such as video payload identifier, ancillary time code, and user-defined packets. The SDI7 includes a wide variety of standard test signals, including SMPTE color bars, pathological test patterns, and a programmable moving zone plate pattern, and it also has the ability to generate full frame test signals created by the user. AV timing signal generation, when used in conjunction with a waveform monitor, can be used to ensure that audio and video are synchronized through a video path. Circle, multi-language text, and color logo overlays may be applied to the generated test signals to check aspect ratio, identify streams, or apply station logos. The SDI7 has a clock/frame trigger output that can be used to trigger an oscilloscope to be synchronous with the video output.
