Spectrum Analyzer Product Introduction

1. Product Overview
The Spectrum Analyzer is a precision electronic instrument designed to measure and display the frequency spectrum of input signals. It is widely used in RF engineering, telecommunications, and research to analyze signal characteristics such as amplitude, distortion, and noise across specified frequency ranges.

2. Key Functions

Frequency Analysis: Measures signal power distribution across 9 kHz to 44 GHz (model-dependent).
Modulation Analysis: Supports AM/FM/PM and digital modulation (QPSK, QAM).
Noise Detection: Identifies spurious signals with DANL (Displayed Average Noise Level) ≤-155 dBm.
Real-Time Processing: Captures transient signals with 100% POI (Probability of Intercept).

3. Working Principles

Superheterodyne Architecture: Downconverts RF signals to IF for precise measurement.
FFT-Based Digital Processing: Enables real-time spectrum updates (up to 200 spectra/sec).
Advanced Triggering: Supports power/edge/frame triggers for complex signal capture.

4. Usage Methods
Step 1: Setup

Connect the input via SMA/N-type connectors (50Ω impedance).
Set frequency span (e.g., 1 MHz–6 GHz) and RBW (1 Hz–3 MHz).

Step 2: Measurement

Use Peak Search to identify dominant frequencies.
Apply Markers for amplitude/frequency readouts.

Step 3: Data Export

Save traces in CSV/PNG format via USB/LAN.
