Network Analyzer

Product Specifications

Technical details and manufacturing context for Network Analyzer

Definition

A network analyzer is a sophisticated electronic test instrument used to characterize the electrical performance of radio frequency (RF) and microwave components, circuits, and systems. It measures the complex transmission and reflection characteristics of two-port networks by analyzing how signals propagate through the device under test, providing essential data for design, verification, and troubleshooting in telecommunications, aerospace, and electronics manufacturing. The instrument generates a known RF signal, applies it to the device under test, and measures both the incident signal and the signals reflected from and transmitted through the device. By comparing the phase and amplitude relationships between these signals, the analyzer calculates S-parameters, which describe how the device responds to electrical signals across a specified frequency range. Modern vector network analyzers use sophisticated digital signal processing to provide highly accurate measurements of impedance, gain, loss, and phase characteristics. Typical specifications include a frequency range of 9 kHz to 6 GHz, a dynamic range of at least 120 dB, a measurement speed of up to 5 ms per point, an output power range of -10 to 10 dBm, two test ports, a measurement accuracy of ±0.05 dB, an operating temperature range of 0 to 50 °C, a humidity range of 20 to 80% RH (non-condensing), a power supply of 100–240 V AC (50/60 Hz), a weight of up to 15 kg, an 8.4-inch touchscreen display, and interfaces including USB, LAN, and GPIB. The instrument is constructed with materials such as aluminum alloy, printed circuit boards, semiconductors, copper conductors, and plastic polymers. This directory entry provides general reference data; for specific model values and standards, always verify with the legal manufacturer or supplier.

Working Principle

Network analyzers operate by generating a known RF signal that is applied to the device under test. The instrument then measures both the incident signal and the signals reflected from and transmitted through the device. By comparing the phase and amplitude relationships between these signals, the analyzer calculates S-parameters, which describe how the device responds to electrical signals across a specified frequency range. Modern vector network analyzers use sophisticated digital signal processing to provide highly accurate measurements of impedance, gain, loss, and phase characteristics.
