The AQ1300 series is a compact and lightweight Ethernet tester that is designed to improve both work efficiency and quality at the same time, with function optimized for the network path testing and maintenance of Ethernet networks up to 1G or 10G depending on model chosen. Easy operation prevents operational errors and stabilizes work quality for routine tasks such as network path testing. Powerful analysis functions help isolate failures during maintenance work. The AQ1300 series has two models, AQ1300 and AQ1301 to choose from depending on the measurement interface and bit rate. You can choose the model suitable for your test needs.

The DLM4000 is a unique to the industry eight-channel mixed-signal oscilloscope suitable to test and debugging applications in the embedded systems, power electronics, mechatronics, and automotive sectors. Available in both 350 MHz and 500 MHz models, the 2.5 GSa/sec DLM4000 features eight analog input channels. The eighth input channel features Flex MSO which converts to a 8-bit logic analyzer at the push of a button; add sixteen additional logic analyzer inputs as an option, for 24-bit logic analysis. Advanced measurement and analysis features such as power analysis and serial-bus analysis, digital filtering, user-defined math, and super-long record lengths (up to 125 Mega Points) make the DLM4000 a super powerful engineering tool. High-resolution 12.1-inch LCD display, compact landscape format, ergonomic and friendly user-interface make it easy to use.

The DLM2000 is a bench-top oscilloscope for electronic design or debug.  It's ergonomic and easy to use, and packed with features.  With bandwidths from 200 to 500 MHz and memory from up to 250 Mpoints, you can be certain there is a DLM2000 to meet your application and budget.  With the DLM2000's industry first “flexible MSO input”, you can choose to activate channel four as an analog input, or use it to acquire 8 bits of logic instead. Modern electronics include analog and digital circuitry—and the DLM2000’s flexible MSO input lets you measure both, including mixed signal triggers and decoding of parallel or serial bit patterns.


Measure and analyze a wealth of signals in real-time and speed up development and fault finding. The DL850E ScopeCorder is a powerful portable data acquisition recorder and oscilloscope that can capture and analyze both transient events and trends up to 200 days. Using flexible modular inputs it combines measurements of electrical signals, physical (sensors) and CAN / LIN serial buses and is able to trigger on electrical power related and other calculations in real-time.
