The 2550 series digital storage oscilloscopes deliver performance and value in 2-channel and 4-channel configurations. With bandwidth from 70 MHz to 300 MHz and 2 GSa/s sample rates, these oscilloscopes offer 24 kpts/Ch waveform memory, 32 automatic measurements, and advanced triggering capabilities including math functions. Engineered to allow you to see more of your signal under test, the 2550 series’ widescreen 7” TFT display offers a significantly larger viewing area than typical economy oscilloscopes (5.7”).

  • Bandwidth up to 300 MHz
  • 2 GSa/s sample rate
  • 4-channel acquisition (on select models)
  • Large 7" widescreen color display
  • 32 automatic measurements
  • FFT plus four additional math functions
  • Built-in context sensitive help system
  • 50 Ω input coupling
  • PC software that lets you remotely control the oscilloscope and capture, save, and analyze waveform data
  • Front and rear panel USB host port for convenient storing and recalling of waveform data, setups, and screenshots on a USB flash drive
  • Standard LAN (supports SCPI) and USB device port (USBTMC compliant) for remote PC control
