Introduction
SV6301A is a handheld Vector Network Analyzer (VNA) with a measurement frequency range of 1MHz to 6.3GHz. It can measure S11 and S21 parameter with a dynamic range of 50dB for S11 and 75dB for S21.
SV6301A is suitable for testing various types of antennas in the MF/HF/VHF /UHF/SHF frequency bands, including shortwave antennas, ISM band antennas, WiFi antennas, Bluetooth antennas, GPS antennas, and more. It can also be used to measure RF components such as filters, amplifiers, attenuators, cables, power dividers, couplers, and duplexers, and supports multiple display formats including amplitude-frequency curves, phase-frequency curves, VSWR (Voltage Standing Wave Ratio), Smith charts, polar plots, group delay, and more. Additionally, SV6301A features TDR functionality.
SV6301A adopts an all-metal casing design that effectively shields against electromagnetic interference. With dimensions of 190mm x 130mm x 30mm, it is compact and portable and includes a rear stand for convenient desktop use. The device uses N-type RF connectors and comes with N-to-SMA adapters and high-quality SMA extension cables for easy connection to various test items.
Thanks to its optimized highspeed processing system, SV6301A offers a measurement speed of 500 points per second, allowing for quasi-real-time measurements, with a maximum scan point setting of 1001 points. The 7-inch high-brightness IPS capacitive touchscreen display ensures clear visibility of screen content even in outdoor settings.
SV6301A features a full touchscreen design with four physical buttons, enabling users to quickly set frequencies, scales, trace on/off, add/delete markers, take screenshots, and perform other operations with ease.
SV6301A is equipped with two 3350mAh 18650 lithium batteries, providing over 3 hours of battery life. It charges via a USB Type-C port, and the included Type-C cable can be used for both charging and data transfer, as well as firmware upgrades.
SV6301A has a built-in 8GB storage card for storing calibration data, SNP files, screenshot images, and more.
