The Tektronix TDS684B is a 1 GHz, 4-channel digital storage oscilloscope capable of a maximum real-time sample rate of 5 GS/s. Designed for demanding high-speed applications, it offers an 8-bit vertical resolution that can be extended beyond 11 bits with averaging, alongside advanced features such as 1 ns peak detect, waveform math, channel deskew, and automated pass/fail template testing. The instrument comes equipped with a color VGA display, a DOS-compatible floppy drive, and a standard suite of connectivity ports including GPIB and RS-232.
