The '''Tektronix 2711''' is a spectrum analyzer with a frequency range of 9 kHz to 1.8 GHz in coax. The minimum resolution bandwidth is 3 kHz, and provides measurement resolution proportional to the frequency accuracy or span. With non-volatile memory (NVRAM) at 28 kB can save up to 18* displays of waveforms and markers, and up to 9* front panel setups, large user-defined key programs, and antenna factor tables. * Opt. 03 adds additional NVRAM bringing saved displays to 108, and 36 front panel setups. | |||
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. | |||
True analog display capability, along with fast sweep speeds and TV Line and TV Field triggering provide demodulation of video carriers for making depth-of-modulation checks or looking at special baseband data, VITS, and other signals. An internal audio amplifier and AM/FM detectors let one hear demodulated signals, using either the build-in speaker or headphone jack for signal identification and troubleshooting and in communications applications. | |||
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 [[N connector]] (50Ω, +20 dBm Max, 100 V DC blocking capacitor); and GEN [[N connector]] (50Ω, 0 to -48 dBm, Opt. 4 Tracking Generator generates a sweep frequency to enable the Spectrum Analyzer to make circuit response measurements, i.e. scalar network analysis). | |||
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]] (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.). | |||
