VNA400 – 40 GHz Vector Network Analyzer
The VNA400 is a high-performance, USB-powered, 40 GHz, 2-port, vector network analyzer. It features a wide frequency range of 40 MHz to 40 GHz, sub-Hz resolution, +/- 1 ppm internal TCXO accuracy and a sweep speed of 2000 points per second at 30 kHz RBW.
Signal Hound’s VNA400 is a high-performance, USB-powered, 40 GHz, two port, vector network analyzer. Advancements in mmWave technology make the VNA400 a must have for RF industry professionals. With a wide frequency range of 40 MHz to 40 GHz, sub-Hz resolution, +/- 1 ppm internal TCXO accuracy and a sweep speed of 2000 points per second at 30 kHz RBW, the VNA400 is a perfect analysis tool whether you are in the lab or out in the field.
The VNA400 is optimized for testing two-port devices, such as filters, amplifiers, and attenuators, as well as one port devices like antennas or VSWR testing. It is powered from a Thunderbolt 3/4 port or USB-C port rated at 15 watts or higher, and draws less than 15 watts. This powerful vector network analyzer can be used to make linear S-parameter measurements on a variety of devices, from amplifiers with up to 30 dB of gain, to attenuators or isolation testing of 120 dB or more. The VNA400’s combination of fast measurements at high dynamic range are useful for antenna pattern testing and filter adjustments.
Engineers in the research and development phase, manufacturing professionals needing verification of components or systems, or technicians in the field, will all find that the VNA400 fits your application. Complete your measurements with confidence and reliability. Communications and wireless professionals can also utilize the compact format of this versatile VNA to troubleshoot issues on site without the limitations of bulky equipment.
