Agilent/Keysight MSO8104A

The Keysight MSO8104A is a 1 GHz mixed-signal oscilloscope engineered for simultaneous acquisition and analysis of analog, digital, and serial protocol signals. It combines 4 analog channels with 16 digital channels to deliver comprehensive visibility into complex embedded systems, microcontroller behavior, and signal integrity across multiple domains.

Key Features MegaZoom III technology enables responsive operation with deep memory acquisitions and fast waveform refresh rates, critical for capturing transient events and intermittent faults. The 350 ps rise time resolves high-speed edge transitions. Pattern triggering and mixed-signal trigger functionality allow precise capture of specific system conditions across both analog and digital domains simultaneously.

Interfaces & Control Standard connectivity includes LAN, USB, GPIB, and XGA video output. LXI Class C compliance ensures integration into networked test environments. Java-enabled LAN interface supports remote instrument control by up to three concurrent users, enabling distributed debug workflows.

Typical Applications Serial protocol analysis (CAN, FlexRay, I2C, SPI), USB 2.0 and Ethernet compliance validation, jitter characterization, FPGA dynamic probing for Xilinx and Altera devices, and automotive embedded system debugging. Optional analysis software provides protocol decode, timing measurements, and compliance testing capabilities.
