S-A-A-2 Vector Network Analyzer User Guide

Introduction

This user guide provides essential information for the basic usage and operation of the S-A-A-2, also known as the NanoVNA V2. OwOComm, the designer of the hardware and firmware, does not manufacture or market end-user products. The specifications and functionality detailed herein are applicable when the design is faithfully replicated by a manufacturing vendor. For support, please contact your supplier, vendor, or distributor. For engineering inquiries, contact OwOwOwOwO123@outlook.com.

Key Features and Specifications

The S-A-A-2 offers a frequency range of 50kHz - 3GHz with a system dynamic range of up to 70dB. It supports sweep rates of 100 points/s and features a user-friendly interface for measurements and calibration.

Key specifications include:

• Frequency Range: 50kHz - 3GHz
• System Dynamic Range: Up to 70dB
• Sweep Rate: 100 points/s
• Power Supply: USB, 4.6V – 5.5V
• Operation Ambient Temperature: 0°C - 45°C

Core Functionality

The S-A-A-2 functions as a Vector Network Analyzer (VNA), measuring reflection and transmission behavior. It supports S11 and S21 parameter measurements for two-port networks and reflection coefficient (S11) for one-port networks. The device features a touch-screen interface, keypad input, and calibration capabilities.

Key operations include:

• Setting measurement frequency ranges (Start/Stop, Center/Span, Zero Span)
• Performing calibration using OPEN, SHORT, LOAD, and THRU standards
• Displaying traces in various formats (LOGMAG, PHASE, SMITH, SWR, POLAR, LINEAR, REAL, IMAG)
• Utilizing markers for precise measurements
• Time domain operation for reflectometry and impulse response analysis

NanoVNA-QT Software Integration

The document also details the use of the NanoVNA-QT PC software, which is derived from software for the xaVNA. This software allows for advanced control, calibration, and firmware updates for the S-A-A-2. Supported platforms include Linux, Windows (7+), and Mac OS (10.11+).
