The Tektronix TDS540C is a 500 MHz digitizing oscilloscope built for signal analysis across design, debug, and R&D workflows. With four full-featured vertical channels, real-time sampling up to 2 GS/s (single channel), and equivalent-time acquisition reaching 100 GS/s, it captures fast transients and rare events reliably. The InstaVu™ acquisition system delivers up to 400,000 waveforms per second, reducing debug cycles by enabling instantaneous visibility of signal behavior. Peak Detect mode resolves 1 ns glitches. Eight-bit vertical resolution extends to over 11 bits with averaging and over 13 bits in Hi-Res mode, supporting precision measurements in low-amplitude signals.
