Keysight (Agilent) 1670G Standalone Logic Analyzer

The Keysight (Agilent) 1670G is a standalone logic analyzer for capturing, displaying, and analyzing digital signals in embedded systems and digital circuits. This compact, all-in-one instrument supports up to 136 channels with configurable channel counts (34, 68, 102, or 136) to match application requirements. The 1670G delivers state analysis at 150 MHz and timing analysis up to 500 MHz (250 MHz at full channel count). Deep memory options—standard 64 K samples, optional 256 K or 2 M samples—enable extended data capture for debugging difficult-to-reproduce faults without complex triggering overhead.
