The Keysight (Agilent) 54624A is a 4-channel, 100 MHz digital storage oscilloscope from the popular 54600 Series. Offering a cost-effective, deep-memory troubleshooting solution, it features 2 MB of patented MegaZoom memory per channel and a 200 MSa/s sampling rate. It includes serial triggering capabilities for I2C, SPI, CAN, and USB, an integrated 5-digit frequency counter, and a high-definition monochrome display with 1000 levels of intensity for superior waveform visualization.
