  • One of the most widely used devices by electrical specialists for its diverse applications
  • Displays voltage on its vertical axis, any other quantity that can be converted to a voltage can be displayed as well
  • Vertical input channels allow you to display two waveforms at the same time for greater accuracy and measurement

BK Precision's 2120B is a dual trace oscilloscope that can simultaneously display two signals and offer high performance at a low price. The auto sweep feature allows the unit to go back to triggered sweep operation once the adequate trigger is applied. The trigger sweep is an oscilloscope's most important function, because it serves to synchronize the sweep oscillator to the input waveform.

  • Equipped with a 8x10 cm CRT display for easy viewing
  • Most comparable products offer 20MHz but this unit offers more advanced technology with a 30MHz bandwidth
  • Four sweep modes for versatility and function:
    • Sweep only
    • Delayed sweep only
    • Main sweep
    • Delayed sweep sharing or X-Y
  • Dual or single trace operation 5 mV/div sensitivity
  • AUTO/NORM triggered sweep operation with AC, TVH, TVV and line coupling
  • Instead of just knowing there is current, you can actually see how the electrical component is operating via a visible sine wave
  • Calibrated 23-step time base with 10x magnifier for accuracy
  • Compact low-profile design
  • 2- year manufacturer’s warranty
