Información

The Tektronix TSG 90 PATHFINDER TV Signal Generator is designed for ease of operation and outstanding portability. It provides a complement of 16 NTSC test signals, including the Safe Area signal. It also provides 13 selectable audio frequencies from 50 Hz to 20 kHz, a 50 Hz to 20 kHz audio sweep, and an audio click channel ID. The two stereo AUDIO outputs may be set to one of three selectable amplitudes: 0 dBu, +4 dBu, or +8 dBu. The PATHFINDER provides character ID capability, as well, storing up to eight messages consisting of two 16 character lines of text. Any one of these text mes- sages may be inserted into the video test signal, or up to four of them may be cycled in a continuous loop (displaying for 1 to 9 seconds each) in any order. These messages may be displayed anywhere in the safe action area of the picture, or the first line of the message may be moved into the vertical interval. In addition to the eight text messages, the PATHFINDER can also store as many as four complete front-panel configurations (User Presets), which can include menu selections, text messages, and tone and cycle information. The PATHFINDER is DC powered, using either an AC adapter with 12V output (18V maximum open circuit), eight AA batteries, or a 9.6V NiCad battery pack (optional accessory). In-instrument charging capability, utilizing the AC adapter, is provided for the NiCad battery pack only. If eight AA NiCad batteries are used, a separate charger must be provided.
