Anritsu S820E Cable & Antenna Analyzer

Overview

The Anritsu S820E is the most advanced handheld microwave Site Master analyzer in its class. It delivers benchtop-level microwave performance in a compact, portable package designed for field technicians and installation teams. The S820E replaces the earlier S810D/S820D models and provides significantly enhanced capabilities with flexible frequency options up to 40 GHz.

Key Features

• Frequency coverage: 1 MHz to 40 GHz (multiple options available)
• 110 dB dynamic range — superior measurement stability at high losses
• Standard Video Inspection Probe (VIP) Mode for fiber connector verification per IEC 61300-3-35
• Fully reversing 2-port vector network analyzer architecture
• Optional Vector Network Analyzer (VNA) Mode with 4 S-Parameter simultaneous measurement
• Optional Vector Voltmeter (VVM) Mode with A/B and B/A ratio capability
• Standard 1-port and 2-port measurement capabilities: Return Loss, VSWR, Cable Loss, Smith Chart, Phase, Distance-to-fault
• Modern connectivity: USB, Ethernet, and full remote control
• S2P file generation compatible with Anritsu benchtop VNA models (VectorStar and ShockLine)
• "Classic Mode" for users migrating from S8X0D series instruments
• Built-in help menu and full instrument user guide
