FEATURES
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 engi-
neers. 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
µ
s/div to 0.1
µ
s/div.
High Sampling Rate
Sampling Rate up to 10 Ms/s (Megasamples per sec-
ond) 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 meas-
urements.
DUAL TRACE FEATURES
Dual Trace
Model 2522B has two vertical input channels for dis-
playing 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 measure-
ments.
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 cali-
brated 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
µ
S/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.
