The 3671 Series from Ceyear are Vector Network Analyzers (VNA) that operate from 100 kHz to 43.5 GHz. They are designed for accurate measurement of amplitude frequency characteristics, phase frequency characteristics and group delay characteristics of any microwave network. These VNAs can perform measurements such as frequency response, single-port, response isolation, enhanced response, full dual-port, and electronic calibration. They support up to 64 channels, and up to 32 measuring windows can be displayed simultaneously, with each window showing up to 16 test traces, making the observation results more visible and the operation more convenient. These analyzers include advanced features, including performance indicators, instrument design, display performance, and software interface functions, while maintaining controlled size, weight, and cooling noise.
The 3671 Series VNA are available in either 2-port or 4-port configurations with a frequency resolution of 0.1 Hz, a dynamic range of 90 to 133 dB, and output power from -6 to 15 dBm. They support a sweep time of 43 ms and up to 200,001 sweep points. These analyzers have a 12.1-inch display and support multiple display formats, including logarithmic amplitude, linear amplitude, phase, group delay, Smith chart, and polar coordinates. They can be controlled via standard interfaces such as USB, LAN, GPIB, VGA, and HDMI. The VNAs require a 110 to 220 V AC power supply and consume less than 300 W of power. They are available in rackmount enclosures measuring 516 × 280 × 490 mm and have 3.4 mm (male) or 2.4 mm (male) connectors. These VNAs are ideal for use in communication applications and academic research, including university laboratories.
