Tektronix, TSG95

The TSG95 is a handheld PAL/NTSC Signal Generator designed for use in installation and maintenance of analog composite video systems. The TSG95 supports both PAL and NTSC standards. It is a great companion for those verifying microwave links, field servicing or system installation. The TSG95 provides a powerful combination of test signals, ID capabilities and other features making it a must for the TV engineer's toolbox or workbench.

Up to eight messages, each containing two 16 character lines, may be stored for later recall. One message may be inserted into the 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 message may be positioned any where within the safe-title area. Creating ID text is fast and simple using the alphanumeric keypad - no tedious scrolling through the alphabet with arrow keys for each character in the ID message. Just type in a message and verify it in the Pathfinder's backlit LCD display.

Up to four complete front panel configurations, including menu selections, current text message and cycle information may be stored for later recall.

Thirteen audio tone frequencies (from 50 Hz to 20 kHz) or an audio sweep are selectable from the Tone Menu. Three tone levels (0, +4 and +8 dBu) are available as well. An audio click sequence can also be selected as an aid in easily identifying and tracing the left and right channels in an installation.

The TSG95 may be operated from the AC adapter provided, 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.

The TSG95 is focused towards installation and maintenance applications.
