The HP/Agilent 54831D is a 4+16-channel mixed-signal oscilloscope combining analog waveform capture with 16-channel logic analysis in a single, time-aligned display. The 600 MHz analog bandwidth instrument simultaneously acquires analog signals on four channels and digital timing data across 16 logic channels, enabling direct correlation of cause and effect in mixed analog-digital circuit troubleshooting.
## Technical Specifications
• **Analog Bandwidth:** 600 MHz
• **Analog Channels:** 4 at up to 4 GSa/s (2-channel mode) or 2 GSa/s (4-channel mode)
• **Digital Channels:** 16 for logic-level timing capture
• **Rise Time:** 583 ps
• **Memory Depth:** 2 Mpts/channel standard (4 Mpts maximum); optional up to 64 Mpts/channel (128 Mpts maximum)
• **Input Impedance:** 1 MΩ typical with standard 1165A passive probe
• **FFT Frequency Range:** DC to 2 GHz (2 channels interleaved), DC to 1 GHz per channel
## Key Features
• Mixed-signal triggering across all 16 digital and 4 analog channels for isolation and analysis of complex signal interactions
