RIGOL RSA800-ADM ANALOG DEMODULATION SOFTWARE

Overview

The RIGOL RSA800-ADM is an advanced Analog Demodulation application software option designed to extend the capabilities of the RSA800 Series Real-Time Spectrum Analyzers. This software option empowers engineers to efficiently characterize and analyze amplitude, frequency, and phase-modulated signals (AM/FM/PM), making it an ideal solution for traditional communication systems, broadcast verification, and field maintenance.

With the ADM application enabled, the spectrum analyzer functions as a dedicated modulation analyzer that delivers precise measurements of carrier power, modulation rates, and deviations. This ensures deep, actionable insights into signal integrity both on the laboratory bench and during mobile field operations.

Product Features

Comprehensive Analog Analysis

The software supports complete analysis of the three core analog modulation formats: Amplitude Modulation (AM), Frequency Modulation (FM), and Phase Modulation (PM). This provides a highly versatile troubleshooting tool for RF devices, legacy communications, and educational labs.

Precise Carrier Power Measurements

Users can measure carrier power within a range from -30 dBm to 20 dBm. The system delivers a nominal carrier power accuracy of ±1.8 dB, ensuring highly dependable and reproducible test results.

Detailed Parameter Decomposition

The ADM platform automatically calculates and displays critical modulation metrics, including modulation rates, AM modulation depth (5% to 95%), and FM frequency deviation (up to 400 kHz). This automated decomposition accelerates troubleshooting and design verification workflows.
