Description: 100 MHz DUAL-TRACE OSCILLOSCOPE
Information:
                                    FEATURES
LOW COST, HIGH PERFORMANCE
B+K Precision Model 2190B is one of the most economical 100
MHz analog oscilloscopes on the market, yet it has all of
the high performance features needed for most applications,
including delayed time base, bandwidth limiter, and
Y axis output. 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.
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 2190B 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 100 MHz.
Fast Rise Time
Rise time is less than 3.5 ns.
Fast Sweep
Maximum sweep speed of 2 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 23
calibrated ranges from 0.5 S/div to 20 nS/div. The delayed
sweep also has 23 calibrated ranges from
0.5 S/div to 20 nS/div. Sweep time is fully adjustable
between calibrated ranges.
X10 Sweep Magnification
Allows closer examination of waveforms, increases maximum
sweep rate to 2 nS/div.
DUAL TIME BASE FEATURES
Dual Sweep Generators
Main sweep gives normal waveform display, delayed sweep may
be operated at faster sweep speed to expand a portion of the
waveform.
Four Sweep Modes
Choice of main sweep only, delayed sweep only, main sweep
and delayed sweep sharing the trace (percentage of
main/delayed sweep adjustable), or X-Y.
Adjustable Start Of Delayed Sweep
DELAY TIME POSition control allows adjustment of delayed
sweep starting point.
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
Bandwidth Limiter
Selectable full bandwidth of 100 mHz or limited bandwidth of
20 MHz to filter high frequency noise from low frequency
waveforms.
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 2 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.
Z-Axis Input
Rear panel Z-Axis input allows intensity modulation.
Supplied With Two Probes
