The Tektronix 2712 is a classic, high-value swept spectrum analyzer designed for RF analysis up to 1.8 GHz. Combining a 4-trace digital storage display with a true analog real-time display, it offers robust capabilities for bench and field use, including an internal frequency counter, built-in preamplifier, and optional tracking generator and quasi-peak detector for EMC measurements.
