The Tektronix 2714 is a CATV spectrum analyzer with a frequency range of 9 kHz to 1.8 GHz. The minimum resolution bandwidth is 300 Hz, and provides measurement resolution proportional to the frequency accuracy or span. With non-volatile memory (NVRAM) at 124 kB can save up to 108 displays of waveforms and markers, and up to 36 front panel setups, large user-defined key programs, and antenna factor tables.
The single and delta markers provide direct readout of frequency and amplitude information of any point along any displayed trace. Or, get the relative (delta) frequency and amplitude information between any two points along any displayed trace or between traces.
The 2714 Cable TV Spectrum Analyzer has features to support the measurements necessary to maintain a functional CATV system 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.
Additional features include Digital Storage Display (selectable acquisition modes of positive peak only, positive/negative peak, Max hold, Waterfall, and an analog sweep when digital storage is off), Ensemble Averaging, Internal Preamp, Internal Calibrator (accessed through Input Menu), Alternate Reference Level Units (dBm, dBmV, dBV, dBµV, dBµW, and dBµV/m), User-Definable Power-on Status, Center Measure, Graticule Illumination (for CRT photography), and Direct Plot/Print (Printers via Opt. 03 GPIB, or RS-232-C interface via Opt. 08).
Front panel inputs/outputs are: RF INPUT BNC connector (75Ω, +20 dBm Max, 100 V DC blocking capacitor); and OPTION Unknown connector (Service manual only indicates that the front panel position is for a Future Option. No internal tracking generators were available like with the other 2710, 2711, and 2712).
Rear panel inputs/outputs are: J101 SMA connector (Female SMA installed for Opt. 15), J102 EXT TRIG BNC connector (10 kΩ, 50V (DC + peak AC)), J103 DB9 connector Female (Not RS-232 compatible. Accessory connector: Pin 1 Video Input, Pin 2 Ground, Pin 3 Video Output, Pin 6 Sweep Gate, Pin 7 Sweep Output, all others unused), J104 Opt. 03: GPIB connector (IEEE Std 488 connector) or Opt. 08: RS-232 interface (Digital Communication Port.).
