The Agilent/Keysight 54642D is a 500 MHz mixed-signal oscilloscope combining analog oscilloscope and logic analyzer functionality in a single instrument. With 2 analog channels and 16 digital logic timing channels, it captures up to 18 simultaneous signals at 2 GSa/s, making it ideal for engineers debugging complex interactions in microcontroller and DSP-based systems. The 8 Mpts record length and 8 MB MegaZoom memory provide deep capture capability with 32 intensity levels for signal visibility across varying signal densities.
