2712 Tektronix Spectrum Analyzer

The 2712 is a 1.8 GHz Spectrum Analyzer from Tektronix. A spectrum analyzer measures the power of spectrums of known and unknown signals. Spectrum analyzers collect information such as the magnitude of an input signal compared to its frequency. As a frequency analyzer, spectrum analyzers’ main use is to document and analyze electrical input signals as well as spectral compositions of other signals.

The Tektronix 2712 Spectrum Analyzer has a straightforward human interface, with conveniently grouped, dedicated front-panel keys and simple, menu-driven functions makes the Tektronix 2712 Spectrum Analyzer easy to learn and use. You can set frequency, span and reference level directly from the front panel.

The Tektronix 2712 provides excellent RF performance, a built-in frequency counter, full programmability, digital and true analog displays, high portability, enough nonvolatile memory for 108 saved displays. A real-time clock provides an on-screen date and time display, plus date/time stamp capability for waveform printouts. Frequency-corrected tuning and phaselock stabilization enhance the ability to resolve close-in signals and reliably demodulate narrowband signals. Sensitivity up to -127 dBm (-80 dBmV) at 300 Hz resolution bandwidth (RBW) lets you see weak signals.

The built-in preamp can improve sensitivity another 12 dB, up to -139 dBm (-92 dBmV). Up to 80 dB on-screen dynamic range ensures visibility of weak signals in the presence of strong ones. A 300 Hz RBW filter with a shape factor <7:1 means you'll see many close-in sidebands and spurious or unexpected signals you might otherwise miss. At the other end of the spectrum the 5 MHz RBW filter is useful when demodulating wideband signals such as actively modulated video carriers.

The built-in signal counter, with 0.5 ppm ±10 Hz accuracy, offers added power for rapidly identifying signals. The capability to choose between digital and true analog displays lets you examine signals for characteristics that are not visible on digital-only displays.
