* Item Description
- B&K Precision's model 2120B is a dual trace oscilloscope that offers high performance at a low price. This oscilloscope is built by and backed by B&K Precision, a company that has been selling reliable, durable, value-priced test instruments for over 50 years.• Dual or single trace operation• 5 mV/div sensitivity• AUTO/NORM triggered sweep operation with AC, TVH, TVV and line coupling• Compact low profile design• cUL certifiedCRT FEATURESRectangular CRTRectangular CRT with large 8 x 10 centimeter viewing area. On Model 2125A, graticule is equipped with variable scale illumination.ConvenienceTrace rotation electrically adjustable from front panel. 0%, 10%, 90%, and 100% markers for rise time measurementsDUAL TRACE FEATURESDual TraceModels 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 CapabilityPermits 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 FEATURESWide BandwidthConservatively-rated −3 dB bandwidth is dc to 30MHz.Fast Rise TimeRise time is less than 12 ns.Fast SweepMaximum sweep speed of 10 ns/div (with X10 MAG) assures high frequencies and short-duration pulses are displayed with high resolution.VERTICAL FEATURESHigh Sensitivity5 mV/div sensitivity for full bandwidth. High-sensitivity 1 mV/div and 2 mV/div using PULL X5 gain control.Calibrated Voltage MeasurementsAccurate voltage measurements (±3%) on 10 calibrated ranges from 5 mV/div to 5 V/ div. Vertical gain fully adjustable between calibrated ranges.SWEEP FEATURESCalibrated Time MeasurementsAccurate (±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 MagnificationAllows closer examination of waveforms, increases maximum sweep rate to 10 nS/div.TRIGGERING FEATURESTwo Trigger ModesSelectable normal (triggered) or automatic sweep modes.Triggered SweepSweep remains at rest unless adequate trigger signal is applied. Fully adjustable trigger level and (+) or (−) slope.AUTO SweepSelectable AUTO sweep provides sweep without trig ger input, automatically reverts to triggered sweep operation when adequate trigger is applied.Five Trigger SourcesFive trigger source selections, including CH 1, CH 2, alternate, EXT, and LINE.Video SyncFrame (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 HoldoffTrigger inhibit period after end of sweep adjustable. Permits stable observation of complex pulse trains.Built-in Probe Adjust Square WaveA 2 V p-p, 1 kHz square wave generator permits probe compensation adjustment.Supplied With Two Probes
