1、Wide Coverage: Comes with a wide frequency range of 50kHz‑3GHz, the vector network analyser promises simpler testing. 2、Better Design: Designed to have 70dB system dynamic range as well as ‑50dB S11 noise floor for more reliable working. 3、Reliable Work: Does not load the initial calibration data at startup, and does not automatically interpolate the calibration data after the user changes the frequency, and must recalibrate or call back the calibration data after each startup and frequency change. 4、Practical Use: Allows for extensive application in measuring 3G network, antenna, shortwave, HF, VHF, UHF and so on. 5、Easy Carrying: Light in weight and compact in size, the easy carrying will bring more convenient to your outdoor use. 1 x Vector Network Analyser Main Body1 x USB Date Cable2 x 30cm SMA Male to Male SS405 RF Cable1 x SMA Calibration Kit OPEN1 x SMA Calibration Kit SHORT1 x SMA Calibration Kit LOAD1 x SMA Female to Female Connector1 x Touch Pen1 x User Manual10 x DIY Accessory Item Type: Vector Network AnalyserFrequency Range: 50kHz-3GHzSystem Dynamic Range (Calibrated): 70dB (up to 1.5GHz), 60dB (up to 3GHz).
