Applications

The Tektronix TDS 600 series — which includes the TDS 620A (500 MHz, 2 GS/s), TDS 640A (500 MHz, 2 GS/s, 4-channel), and TDS 644A (500 MHz, 2 GS/s, 4-channel with extended record length) — are mid-1990s high-performance digitizing oscilloscopes widely used in electronics development, telecommunications testing, and research laboratories. Performance Verification manuals like this one are essential for calibration labs, field service engineers, and maintenance technicians who need to confirm an instrument meets Tektronix's warranted specifications after repair, storage, or periodic recertification. The procedures step through every major subsystem — DC gain and voltage measurement accuracy, analog bandwidth, delay between channels, long-term sample rate and delay time, trigger accuracy, and output signal levels — using external reference equipment. This manual is also a valuable resource for users who need the instrument's warranted and typical characteristics in a single printed reference.
