Tektronix 1740A Waveform Generator Instrument

The Tektronix 1740A Waveform Monitor Instrument is an analog waveform and vectorscope monitor used for monitoring and analyzing composite NTSC video signals in professional broadcast environments. It features a high-brightness CRT with an internal illuminated graticule for precise composite video waveform monitoring and chrominance vector analysis, supports analog composite video inputs, and offers remote control capability. Powered from 90–250 VAC, 50/60 Hz, with a maximum draw of 110 VA, the 1740A is designed for benchtop or rack-mount installations and is commonly deployed in broadcast facilities, production studios, mobile broadcast trucks, and post-production environments for calibration, maintenance, and upgrades by maintenance technicians, broadcast engineers, and system integrators. Related Tektronix replacements in this family include the 1745A, 1750A, and WFM6100 waveform/vector monitors.
