The Tektronix 2714 is a CATV spectrum analyzer with a frequency range of 9 kHz to 1.8 GHz.

The 2714 Cable TV Spectrum Analyzer supports CATV-specific functions like automatic positioning of visual aural carriers, visual and aural carrier levels and frequencies for selected channels, survey of system visual and aural carrier levels and frequencies, depth of modulation, aural carrier deviation measurement, visual carrier-to-noise measurement, and visual to carrier amplitude and frequency difference measurements.
