The Tektronix TDS460 is a 4-channel digital storage oscilloscope delivering 400 MHz bandwidth with 100 MS/s real-time sampling across all channels. Built for precision measurement in demanding environments, this instrument combines high acquisition confidence with practical portability for field troubleshooting, production testing, and design validation. Engineers gain access to advanced signal analysis capabilities through multiple acquisition modes, flexible triggering options, and calibrated vertical measurement accuracy.
