The Tektronix 1765 is a dual-standard waveform monitor and vectorscope for NTSC 525/60 and PAL 625/50 video signal analysis. It combines composite and component video monitoring with eight loop-through inputs, enabling operators to analyze complex broadcast signals across mixed-format environments. The instrument delivers intuitive front-panel control over waveform displays, vectorscope functions, and optional SCH/color framing evaluation. Its microprocessor-controlled phase shifter maintains precise vector positioning, while programmable cursors and up to x10 vertical and x25 horizontal magnification support detailed signal inspection. Audio monitoring includes stereo display with 200 kHz -3 dB bandwidth and phase match better than 1 degree at 20 kHz. Time code verification, user presets, and NTSC/PAL graticule support streamline broadcast monitoring workflows.
