The built-in LAN interface allows you to easily
capture screenshots at a user-configurable
refresh rate with a web browser. A GUI simulating 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.
Beneficial for applications such as I C serial data
streams, deep memory lets you capture waveforms 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.
