The Tektronix TAS455 is a 2-channel, 60 MHz analog oscilloscope engineered for signal analysis, waveform measurement, and general-purpose electronic troubleshooting. Built on a hybrid circuit architecture, it delivers 100 MS/s real-time sampling per channel with 8-bit vertical resolution and a 6-inch monochrome CRT display. The instrument supports dual time bases, multiple trigger modes including video triggering (NTSC, PAL, SECAM), and auto setup functionality for rapid signal acquisition and measurement.
