The Tektronix 1735HD is a multi-standard waveform monitor for precision video signal analysis across HD, 525-line/60-field, and 625-line/50-field production formats. Six wide-bandwidth input channels accept composite or component signals, delivering flat frequency response to 30 MHz with excellent return loss. DC restoration and unclamped display modes accommodate diverse signal conditioning requirements. The instrument supports tri-level and bilevel sync inputs, with optional TTL remote sync triggering. Dual filter capability allows simultaneous filtered and unfiltered line or field observation on a single signal for detailed quality assessment.
