20 MHz DIGITAL STORAGE/ANALOG OSCILLOSCOPE

Información

LOW COST, HIGH PERFORMANCE B+K Precision’s Model 2522B is one of the lowest cost digital storage oscilloscopes in the industry, yet it includes all the basic features needed by most technicians and engineers. Unlike other digital oscilloscopes, it has a full analog mode with infinite resolution. Digital storage modes include refresh, roll, and single sweep. Equivalent time storage techniques allow storage of repetitive waveforms up to 20 MHz. 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. DIGITAL STORAGE FEATURES High Resolution 2048 samples across the width of the screen (200 samples per division) assures good resolution of stored waveforms. 1024 samples taken at sweep rates of 10 ms/div to 0.1 ms/div. High Sampling Rate Sampling Rate up to 10 Ms/s (Megasamples per second) for storing one-time events down to 50 nS. Slow Event Display X100 time base selections extend sweep time to 50 seconds/division. Excellent for displaying slow speed events. Equivalent Time Sampling Allows repetitive waveforms up to 20 MHz to be stored. Pretrigger Capture Permits viewing activity before the trigger occurs. Selectable 0%, 25%, 50%, or 75% pre-trigger view. Plotter Output Analog output plus TTL Pen-Down control for strip chart recorder or X-Y plotter. 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. DUAL TRACE FEATURES Dual Trace Model 2522B 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. HIGH FREQUENCY FEATURES Wide Bandwidth Conservatively-rated -3 dB bandwidth is dc to 20 MHz. Fast Rise Time Rise time is less than 18 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-sen- sitivity 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 21 calibrated ranges from 0.5 s/div to 0.1 mS/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 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, 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. OTHER FEATURES X-Y Operation Channel 1 can be applied as horizontal deflection (X-axis) while channel 2 provides vertical deflection (Y-axis). Built-in Probe Adjust Square Wave A 0.5 V p-p, 1 kHz square wave Generator permits Probe compensation adjustment. Channel 2 (Y) Output A buffered 50W output of the channel 2 signal is available at the rear panel for driving a frequency Counter or other instruments. The output is 50 mV/div (nominal) into 50W. Supplied With Two Probes
