HP / Agilent 54520C 2 Channel, 1 GSa/s Color Digitizing Oscilloscope

The HP/Agilent 54520C is a 2-channel digitizing oscilloscope delivering 500 MHz analog bandwidth and real-time sampling to 1 GSa/s. Purpose-built for high-speed signal capture and analysis, this instrument combines a color flat-panel TFT display with sophisticated triggering architecture and automated measurement capabilities. The 32 K acquisition memory per channel supports sequential single-shot acquisition for capturing successive transient events without dead time, while 400 Kbytes of sequential capture storage accommodates extended waveform sequences. Peak detect resolution reaches 1 ns for accurate glitch identification.
