Tektronix 1735

The Tektronix 1735 is a multi-format waveform monitor for high-definition and standard-definition television production. It delivers real-time analysis of composite or component video signals across six wide-bandwidth input channels, supporting HD, 525-line/60-field, and 625-line/50-field standards with both tri-level and bilevel sync signals. Purpose-built for broadcast and medical video monitoring, the instrument combines precise timing measurements with flexible signal comparison and display modes.
