PC Connectivity
Deep Memory
Beneficial for applications such as I2C serial data
streams, deep memory lets you capture wave-
forms in high resolution while maintaining a high
sample rate over a longer period of time. Up to
2.4 Mpts of memory can be captured in as fast
as 5 seconds* using binary transfer through the
LAN or USB interface.
The built-in LAN interface allows you to easily
capture screenshots at a user-configurable
refresh rate with a web browser. A GUI simulat-
ing the front panel provides full DSO control.
This feature can be useful in an education
setting.
Comsoft software provides seamless integration
between the oscilloscope and PC. Capture and
transfer waveforms, screen images, setups, and
measurement results to a Windows PC via the
LAN and USB device port on the back of the
instrument. A USB host port on the front allows
for quick and easy screen saving to a USB flash
drive.
*Typical time based on LAN speed testing.
Powerful Measurement Functions
Multi-Language Interface
Waveform Recorder
Operate the oscilloscope in a language you
understand best with the built-in multi-language
interface. Choose from English, Simplified
Chinese, Traditional Chinese, Korean, Japanese,
French, German, Russian, Spanish, Portuguese,
and Polish.
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.
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.

Graphical Help Feature
Generate, edit, and upload arbitrary
waveforms to the scope using the
intuitive Comsoft PC software.
Quick and easy single-button capture func-
tion lets you acquire and store your signal
directly from the oscilloscope’s channels to
the generator’s internal memory. Not only
can CH1 and CH2 signals be captured, but
math functions applied to the channels can
also be captured and stored.
Display a graphical illustration explaining the
parameters of the built-in arbitrary waveforms
and modulation schemes. This is a convenient
tool for students and new users.
Remotely connect to the scope and
download waveform data from custom
software using SCPI commands.
Wide Array of Modulation Schemes
30 Built-In Arbitrary Waveforms
The built-in arbitrary waveform generator is
capable of many different types of modulation for
various applications. Modulate your waveforms
with AM, FM, FSK, PSK, and PWM modulation
schemes and use any of the 30 built-in wave-
forms as the modulating waveform.
Store user arbitrary waveforms internally (up to
10 waveforms) or externally as an ARB or CSV
file to a USB flash drive.
Take advantage of the generator’s already
built-in waveforms that fit your application.
