FEATURES
20 MHz Bandwidth
Capture signals from AC/DC drive motors, sensors,
actuators, line and control voltages, UPS and
industrial machines.
Cursor Readout
Allows you to measure the width and amplitude of the signal and
display it on the screen instead of trying to figure it out manually.
Decibels
Allows you to accurately measure sound signals.
Pre and Post Triggering
View the waveform before and after the point the scope triggers
at to find glitches and other anomalies with the signal.
Trend Mode
Graph readings over a predetermined time period to check for
surges or dropouts.
Dual Input
View two waveforms on the display for comparison and trou-
bleshooting.
True RMS DMM
Measure AC/DC volts up to 600V, frequency to 20 MHz,
and resistance to 20 Meg ohm. True RMS allows you to obtain
accurate measurements of non-sinusoidal AC voltage and cur-
rent waveforms found in controls and circuits.
Real Time Sample Rate
Capture spikes and dropouts of industrial signals with
real time sampling of 25 megasamples per second.
Bright LCD Backlight
Adjust brightness levels for clarity under any light condition.
Optically Isolated RS232 Output
Transfer data safely without a direct connection to your
computer’s circuitry.
Continuous Autoset
Feature automatically determines the correct vertical
and horizontal settings for optimum waveform viewing. Autoset
provides hands free operation while moving between test points.

FAQ
Why do you need a 20 MHz oscilloscope?
To measure signals and voltage anomalies, and to
look for glitches that may damage or even shut
down electronic machinery. View sine waves on
power supplies, motors, and bead board circuitry.
Pinpoint certain glitches on the sine wave to zero in
on the problem and monitor changing patterns or
distortion in electrical currents.
What are the different waveform patterns
displayed on your handheld oscilloscopes?
An AC waveform known as sine wave displays
voltage against time in the shape of a sine curve.
The saw tooth waveform displays a ramped angle
and a sharp downward return to its earlier value.
(Its display pattern resembles the cutting edge of
a saw.) A square waveform graphically plots a
series of vertical square shapes repeated with
spacing between peaks.
Why is it important to have Trend Mode?
Trend Mode is great for monitoring sudden
intermittents caused by loose connections, dirt,
or damaged wires. By setting the minimum and
maximum parameters, you can monitor, even
record the changes.
What is the purpose of triggering?
Simply zoom in on certain parts of the sine wave
and “hold” to measure and monitor that particular
part you are reading. A must have when searching
for glitches and distortion on all measurements.
