The Tektronix 1434 is a video noise generator plug-in for the TM500 system.

This video noise generator features calibrated noise levels, white noise, impulse noise with selectable polarity, variable width and density, hum (50 or 60 Hz), noise gating, calibrated video attenuation for NTSC, PAL, PAL-M and SECAM systems. The 1434 occupies two spaces in a TM500 system.
