FULL FEATURED OSCILLOSCOPES
THAT WON’T BREAK YOUR BUDGET
Models 2534, 2540 & 2542 dual channel
Digital Storage Oscilloscopes deliver an
unmatched combination of performance and
value. Analog style controls combined with an
Auto measurement function make these
oscilloscopes easy to use. Advanced features
such as FFT function, digital filtering, waveform
recorder, delayed sweep/zoom, mask testing
and automatic measurements provide you with
powerful tools to debug your circuits.
The oscilloscopes come with PC Software that
lets you easily capture, save and analyze
waveforms and measurement results. Unlike
other DSOs in this price category, each model
includes two 150 MHz high performance passive
probes that will not limit the bandwidth of your
measurement system.
The 2534, 2540 & 2542 are ideal
oscilloscopes for use in education and training,
design and debug, service and repair.

Connect your USB flash drive to conveniently
store and recall waveform data (binary or csv),
setups and screen shots (bmp format). You can
also update the oscilloscope’s firmware from
this port.
Ea s y s et u p an d u se
The Auto button identifies the input signal and
automatically sets up the vertical, horizontal
and trigger controls to produce a useable
display.
You can automatically adjust the timebase to
view the waveform as single cycle or multiple

Wa vef or m Rec o rder
Mas k t es t in g
Use the oscilloscope’s delayed sweep feature
to zoom in on a particular area of a signal in
real time while viewing the entire captured
waveform simultaneously.
Monitor and analyze long term signal behavior
by recording data continuously over an
extensive period of time and playing it back for
post acquisition analysis. Data is recorded in a
sequence of up to 1000 frames of 4 k data
points each and the time interval between each
frame is adjustable from 1 ms – 100 s. The
data can be saved in a single file to internal
memory or USB flash drive.
D igi t al f il te r in g
Create a user defined mask (pass/fail limits)
and automatically compare it against the input
signal from CH1 or CH2. This feature is ideal
for manufacturing test applications that
require instant go/no go test results.

Display and measure the input signal’s
frequency spectrum. Select one of the 5 FFT
windows: Rectangular, Hanning, Hamming,
Blackman and Flattop. Use cursors to
measure the spectral component’s magnitude
and frequency.

The included Comsoft PC software provides
full access to the oscilloscope’s display,
measurements waveform data and front panel
controls through the rear panel USB device
port.
The software provides a seamless synchroniza-
tion between the oscilloscope and PC,
effortlessly allowing quick imports of captured
waveform data and measurement results into
Microsoft Excel for further analysis.
All oscilloscope parameters can be easily
controlled via a PC without the need for
programming. Front panel knobs can be
emulated via a virtual panel. Alternatively,
parameters can be selected from a menu.

Noise free signal after applying digital lowpass filter
Navigate your USB flash drive directory and
files with ease. Store and retrieve waveform
data, screen shots and setups complete with
time and date stamp and user defined names.
Filter out unwanted signal components, such
as various types of noise, with the built in
digital filter. Select from lowpass, highpass,
bandpass or notch filter. The limits are
adjustable over a wide range. The available
range varies with each timebase settings. (e.g.
the lowpass filter corner frequency can be set
as low as 40 Hz when selecting a
timebase of 5 ms/div).
