Wide Dynamic Range

It has a dynamic range of up to 140dB (IFBW=10Hz) for accurate measurement of devices with high rejection ratio.

Super Fast Sweep

Its sweep speed is significantly improved compared with the previous-generation products, which can improve the measurement reaction speed and improve the measurement efficiency in high-speed cable testing, chip production line testing, filter commissioning and other fields.

Fast Analysis of Signal Integrity

It has the function of generating and analyzing virtual eye diagram based on network parameters. Depending on the standard of high-speed digital communication, it can perform efficient Pass/Fail testing using a pre-defined eye diagram template. It can apply jitter, noise and other interference on the simulated eye diagram, and simulate the simulated eye diagram of different positions of high-speed link in real environment by adding correction algorithms such as pre-weighting and equalization.

Desktop Model (2U)

It is applicable to automatic testing, system integration, unmanned factory, and other application scenarios.
