A comprehensive serial component test set

The TSG601 Serial Component Generator and the SDA601 Serial Digital Analyzer form a comprehensive test set for serial component television system installation and maintenance. Each convenient, handheld instrument complements the other and the set excels in its capability for stress testing the television system data path.

The TSG601 Serial Component Generator provides Serial Digital Interface (SDI) check field test signals that stress receiver clock recovery and phase lock loop circuitry. Data signal launch amplitude may be varied over the SMPTE specification range to check equalizer performance, and a built-in 50 meter cable simulator may be used to quickly check available signal strength margin.

The SDA601 Serial Digital Analyzer provides analysis of the incoming digital television signal with the push of a button, quickly identifying data errors and indicating the presence and status of SMPTE RP165 and other ancillary (ANC) data signals. The analysis results may be displayed on the built-in LCD screen, on a picture monitor or transferred directly to a printer or PC for further analysis.

In addition to a full complement of system test signals, the TSG601 includes signals to test DAC performance and the accuracy of subsequent encoding into the PAL or NTSC domain.

Both the TSG601 and SDA601 comply with industry standards for serial component television data transmission. They may be used as a set for data path testing or individually to check performance and compliance of digital source and receiving equipment.

Variable Output Amplitude. The TSG601 serial output amplitude (launch amplitude) may be varied over the SMPTE ±10% specification.

ANC Data. Full-field CRC, active picture CRC and embedded audio may be added to the TSG601 blanking time between the timing reference portions (EAV and SAV) of the serial output signal.

Embedded Audio. Up to four channels of audio (reference tone or digital silence) may be embedded into the TSG601 signal as ancillary data.

Return Loss Alarm. The TSG601 serial digital output line is monitored with a return loss detector circuit. This circuit displays an alarm indicator in the event of improper termination (short, open or 75/50 Ohm mismatch).

Passive Cable Simulator. A cable simulator circuit, equivalent to approximately 50 meters of Belden 8281 cable, is included as a BNC loopthrough connector in the TSG601 for quick headroom evaluation.

Character ID. Up to eight messages, each containing two 16 character lines, may be stored for later recall. One message may be inserted into the TSG601 video test signal, and up to four may be cycled into the test signal in a continuous loop (displaying each message for 1 to 9 seconds). The position of the message may be adjusted to anywhere within the safe-title area.

User Presets. Up to four complete front panel configurations, including menu selections, text messages, embedded audio and cycle information may be stored in the TSG601 for later recall.

Other capabilities:

DC Powered. The TSG601 may be operated from the provided AC adapter, from eight AA size batteries or from an optional accessory 9.6 V NiCad battery pack. Battery recharging capability, utilizing the AC adapter, is provided for the NiCad battery pack only.

Handheld Operation. The TSG601 is a handheld instrument focused toward installation and maintenance of serial component television systems. Together, the TSG601 and the SDA601 provide a means of evaluating system performance under both stressful and normal operating conditions.
