FNIRSI® DLA-16 Plus Logic Analyzer, USB 3.0, 4Gbit is a high-speed 16-channel USB logic analyzer designed for capturing, viewing, timing, and decoding digital signals in embedded systems and electronic circuits. It provides up to 500MHz buffer-mode sampling across all 16 channels, while selected-channel operation can reach up to 1GHz sampling. The analyzer incorporates 4Gbit hardware memory for high-speed buffer acquisition and supports USB 3.0 communication with transfer speeds up to 5Gbps. It supports more than 120 protocol decoders along with custom protocol decoding, making it suitable for debugging interfaces such as UART, SPI, I²C, CAN, RS232, RS485, and other digital communication buses. It also provides Buffer, Stream, and Roll acquisition modes and four 3.3V PWM output channels with a frequency range of 1Hz to 20MHz.
