      • 5 mV/div sensitivity
      • AUTO/NORM triggered sweep operation with AC, TVH, TVV and line coupling
      • Compact low profile design
      • cUL certified


      CRT FEATURES
      Rectangular CRT
      Rectangular CRT with large 8 x 10 centimeter viewing area. On Model 2125A, graticule is equipped with variable scale illumination.

      Convenience
      Trace rotation electrically adjustable from front panel. 0%, 10%, 90%, and 100% markers for rise time measurements


      DUAL TRACE FEATURES
      Dual Trace
      Models 2120B and 2125A each have two vertical input channels for displaying two waveforms simultaneously. Selectable single trace (either CH 1 or CH 2) or dual trace. Alternate or chop sweep selectable at all sweep rates.

      Sum and Difference Capability
      Permits algebraic addition or subtraction of channel 1 and channel 2 waveforms, displayed as a single trace. Useful for differential voltage and distortion measurements.


      HIGH FREQUENCY FEATURES
      Wide Bandwidth
      Conservatively-rated −3 dB bandwidth is dc to 30MHz.

      Fast Rise Time
      Rise time is less than 12 ns.

      Fast Sweep
      Maximum sweep speed of 10 ns/div (with X10 MAG) assures high frequencies and short-duration pulses are displayed with high resolution.


      VERTICAL FEATURES
      High Sensitivity
      5 mV/div sensitivity for full bandwidth. High-sensitivity 1 mV/div and 2 mV/div using PULL X5 gain control.

      Calibrated Voltage Measurements
      Accurate voltage measurements (±3%) on 10 calibrated ranges from 5 mV/div to 5 V/ div. Vertical gain fully adjustable between calibrated ranges.

      SWEEP FEATURES
      Calibrated Time Measurements
      Accurate (±3%) time measurements. The main sweep has 23 calibrated ranges from 2 S/div to 0.1 µS/div.  Sweep time is fully adjustable between calibrated ranges.

      X10 Sweep Magnification
      Allows closer examination of waveforms, increases maximum sweep rate to 10 nS/div.


      TRIGGERING FEATURES
      Two Trigger Modes
      Selectable normal (triggered) or automatic sweep modes.

      Triggered Sweep
      Sweep remains at rest unless adequate trigger signal is applied. Fully adjustable trigger level and (+) or (−) slope.

      AUTO Sweep
      Selectable AUTO sweep provides sweep without trig ger input, automatically reverts to triggered sweep operation when adequate trigger is applied.

      Five Trigger Sources
      Five trigger source selections, including CH 1, CH 2, alternate, EXT, and LINE.

      Video Sync
      Frame (TV V) or Line (TV H) triggering selectable for observing composite video waveforms. TV-H position can also be used as low frequency reject and TV-V position can be used as high frequency reject.

      Variable Holdoff
      Trigger inhibit period after end of sweep adjustable. Permits stable observation of complex pulse trains.

      Built-in Probe Adjust Square Wave
      A 2 V p-p, 1 kHz square wave generator permits probe compensation adjustment.


      Supplied With Two Probes
