Introduction

     

     SV4401A is a handheld Vector Network Analyzer (VNA) with frequency range of 50kHz ~ 4.4GHz. It can be used for S11 and S21 measurements. The S21 dynamic range of SV4401A is 75 dB, while the S11 dynamic range is 50 dB.

     SV4401A is suitable for antenna testing of MF/HF/VHF/UHF bands, such as shortwave antennas, ISM band antennas, WiFi antennas, Bluetooth antennas, GPS antennas, etc. It can also be used to measure filters, amplifiers, attenuators, cables, power dividers, couplers, duplexers and other RF components. SV4401A supports a variety of display formats: Log Mag, Linear Mag, Phase, Smith R+jX, Smith R+L/C, VSWR, Polar, Group delay, Resistance, Reactance, etc. In addition, SV4401A supports TDR function which is useful for cable lengths measurement.

     SV4401A is designed with metal case, which is durable and can effectively shield electromagnetic interference. The dimension of SV4401A is 190mmx130mmx30mm, and a back bracket is designed for desktop use. The RF interface of SV4401A is N-type femal connector and a pair of N-to-SMA adapters are included, witch can be used to connect DUTs with SMA interfaces.

     With the optimally designed signal processing system, the scan speed of SV4401A is 400 points/s, which enables a quasi-real-time measurement, and the maximum scanning points is up to 1001. The screen of SV4401A is a 7-inch high-brightness IPS capacitive touch screen, which allows users to see the screen content clearly in outdoor. SV4401A adopts a full touch screen design, with 4 physical buttons, users can quickly set frequency range, scale, turn on/off traces, add/delete markers, screenshots, and so on. The operation is quite convenient and smooth.

     The SV4401A has two built-in 3350mAh 18650 lithium batteries with a battery life of up to 4 hours. The charging interface is USB Type-C, and the included Type-C cable can be used to charge the device and also for data transfer. At the same time, the SV4401A has a built-in 8GB memory card, which can be used to store calibration status, snp files, screenshots, etc.
