  • Retro-Cool CRT-based Vector Screen showing Basic Real-time & Storage Oscilloscope
  • Exclusive one-shot and intermittent phenomena are simple to capture using the digital storage function.
  • Using the pre-trigger function, it is possible to observe the rising edge of a waveform which occurs before the trigger occurs.
  • Non-repeating events can be observed as clean waveform using the digital storage function.
  • Low-speed phenomena can be observed as a trace using the digital storage function (roll mode).
  • External plotter functionality enables hardcopies of CRT waveform data.
  • Averaging can be used to reduce noise, providing summary signal of interest.
  • Captured waveform can be saved to internal memory and recalled for comparison.
  • RS-232C serial interface usable to transfer stored waveform data.
  • Dual cursors can be enabled to make accurate measurements of voltage, time, and frequency.
  • After waveform capture, it can be displayed in expanded form with interpolation (linear or sine).
  • Using sweep time auto-ranging, the sweep rate setting automatically optimised in accordance with the input signal frequency.
  • Trigger lock hold the sum of the hold-off time and sweep time for stable trigger of complex pulse trains.
  • Frequency of the channel selected as the trigger signal is automatically counted.
