Tektronix 2465BCT Oscilloscope, 400 MHz, 4-Channel with Counter Timer

The Tektronix 2465BCT is a 400 MHz, four-channel analog oscilloscope built for design, service, and manufacturing environments. Its integrated counter/timer delivers precise frequency and time interval measurements with 1% timing accuracy and 20 ps resolution. The portable instrument combines a CRT display with intensity modulation, Auto Setup, automatic measurements, and cursor-based voltage/time readouts to accelerate signal analysis across demanding field and bench applications.
