The HP/Agilent 54641A is a 2-channel digital storage oscilloscope delivering 350 MHz bandwidth and 2 GSa/s maximum sample rate for demanding electronics testing and signal analysis. The instrument combines 8 MB of interleaved MegaZoom deep memory with a high-definition 7-inch monochrome CRT display capable of rendering up to 25 million vectors per second. Advanced triggering across edge, pulse width, pattern, and protocol modes—including CAN, I2C, LIN, SPI, and USB—enables precise signal capture in complex systems.
