FEATURES DUAL TRACE FEATURES Dual Trace Model 2120 has 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. CRT FEATURES Rectangular CRT Rectangular CRT with large 8 x 10 centimeter viewing area. Convenience Trace rotation electrically adjustable from front panel. 0%, 10%, 90%, and 100% markers for rise time measurements. VERTICAL FEATURES High Sensitivity 5 mV/div sensitivity for full bandwidth. 1 mV/div sensitivity with PULL X5 at reduced bandwidth. 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. Model 2120 has 19 calibrated ranges from 0.5 s/div to 0.5 |is/div. Sweep time is fully adjustable between calibrated ranges. X10 Sweep Magnification Allows closer examination of waveforms, increases maximum sweep rate to 50 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 trigger input, automatically reverts to triggered sweep operation when adequate trigger is applied. Five Trigger Sources Five trigger source selections, including CH 1, CH 2, ALT, EXT, and LINE. In ALT mode, each waveform becomes its own trigger (alternate triggering). Three Trigger Coupling Choices Selectable AC, TV H (Line), or TV V (Frame) trigger coupling. Video Sync Frame (TV V) or Line (TV H) triggering selectable for observing composite video waveforms. OTHER FEATURES X-Y Operation Channel 2 can be applied as horizontal deflection (X-axis) while channel 1 provides vertical deflection (Y-axis). Built-In Probe Adjust Square Wave A 0.2 V p-p, 1 kHz square wave Generator permits Probe compensation adjustment. Channel 1 Output A buffered 50Q output of the channel 1 signal is available at the rear panel for driving a frequency Counter or other instruments. The output is 50 mV/div into 50Q. Supplied With Two Probes Low Boy Configuration Low profile housing saves bench space and allows Oscilloscope to be carried like a briefcase.
