HF-ET-801 Vector Network Analyzer

Product Overview

The HF-ET-801 Vector Network Analyzers are suitable for wireless communication, CATV, education, automotive electronics and other fields. They are used for performance measurement of RF components such as filters, amplifiers, antennas, cables and CATV taps.

Adopting Windows operating system, they support error calibration, time‑domain analysis and fixture simulator functions. Multiple display formats are available: logarithmic magnitude, linear magnitude, VSWR, phase, group delay, Smith chart and polar diagram.

It provides multiple calibration methods including frequency‑response, one‑port, response‑isolation, enhanced‑response, full two‑port, fast SOLT calibration and electronic‑calibration. Multi‑channel and multi‑window display is supported. Interfaces include USB, LAN, GP‑IB and VGA.

It can rapidly and accurately measure magnitude, phase and group‑delay characteristics of S‑parameters for devices under test, featuring high‑efficiency and powerful error‑correction capability.

Main Features

• Delivers dynamic range up to 125 dB, enabling accurate measurement of high‑rejection‑ratio devices.
• It is available with a four‑port option, which enables measurement of all 16 S‑parameters of a four‑port network with a single connection, and supports balanced‑parameter measurement.
• Trace noise as low as 0.001 dB rms ensures superior test accuracy of the network analyzer.
• Supports up to 64 independent measurement channels for fast execution of complex test scenarios.
• Powerful data‑analysis functions including ripple test, bandwidth test and limit test facilitate pass‑fail judgment and improve test efficiency.
• Time‑domain analysis function is supplied as standard.
• The fixture simulator emulates various measurement scenarios in R&D and production to obtain corresponding measurement results rapidly in real‑time.
• Equipped with LAN and GP‑IB interfaces for remote control and system interconnection, together with four USB ports.
