The Tektronix 2710 Spectrum Analyzer provides excellent RF performance, a built-in frequency counter, full programmability, digital and true analog displays, high portability, enough nonvolatile memory for saved displays and much more. A straightforward human interface, with conveniently grouped, dedicated front-panel keys and simple, menu-driven functions makes the 2710 easy to learn and use. You can set frequency, span and reference level directly from the front panel. 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) 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.
