The Tektronix 1741C is an analog dual-standard waveform monitor for NTSC and PAL composite and component video signal analysis. It delivers precise monitoring across four 75-ohm BNC loopthrough inputs with auto format detection, supporting signal levels from -1.8V to +2.2V (DC + peak AC). The instrument combines waveform, vector, and picture displays with timing analysis, VITC/LTC decode, and screen capture via USB or Ethernet for broadcast, production, and lab environments.
