Feature:1. MULTI FUNCTION: Not only can test the standing wave impedance of the antenna, but also can debug the duplexer, the insertion loss of the filter, isolate and attenuate test cable, shorten the coefficient of antenna amplifier, phase, amplification2. MEET ORIGINAL TECHNICAL SPECIFICATIONS: 3GHz vector analyzer is co designed with for OwOComm. According to the LGPL license agreement, manufactured in full accordance with the v2_2 file released by the development department of for OwOComm, in line with the original technical specifications, please go to the following to update the firmware: github vna‑v2, VNA2‑firmware, release3. RE CALIBRATED OR RECALLED WHEN FREQUENCY CHANGE: SAA‑2N/VNA_V2.2 uses a similar user interface to VNA, but uses a different technical architecture, will not load initial calibration data at startup, nor will automatically insert calibration data after the user changes the frequency data, must be re calibrated or recalled after each power on and frequency change4. TRANSMISSION MEASUREMENT: S21 support 70dB (50KHz‑1.5GHz), 60dB (1.5GHz‑3GHz). Reflection measurement S11 for ‑50dB (50KHz‑1.5GHz) and ‑40dB (1.5GHz‑3GHz); Antenna analyzer support 1.005 (50KHz‑1.5GHz), 1.02 (1.5GHz‑3GHz); You can flip the display to easy to use5. FOR VARIOUS SOFTWARE: The device can be controlled from a PC via for VNA-QT software and supports for Linux, for (7+), for OS X plans. Also supports VNA-Saver to extract data for display on computer and save to for Touchstore fileSpecification:Item Type: Vector AnalyzerFrequency Range: 50kHz - 3GHzSystem Dynamic Range (calibrated): 70dB (up to 1.5GHz), 60dB (up to 3GHz)S11 Noise Floor
