Portable and User-Friendly

KC901 is made for portability, with minimal volume and weight advantages in the same class of instruments, very suitable for field experiments, on-site construction and other uses. With the built-in lithium battery and easy operating design, It can support a full day of intense measurements. With USB Type-C charge ability makes engineer do not need to carry a DC adapter.

No-compromise RF performance

 

Precision RF front-end circuitry coupled with a high-performance ADC, enabling it to achieve trace noise levels <0.005dB .  Anti-crosstalk circuit design and strict shielding allows the KC901 to obtain a better dynamic range of transmission measurements.

Expand Instruments with Free Software

Free KCSDI software makes it easy to expand the measurement capabilities in the lab and measure remotely via an Ethernet connection.

We also provide the programming manual, you can connect the KC901 via RJ45 or usb and integrate it into your test solution.
