    A compact USBconnected device with 16 channels at 200 M Sa/s sampling rate. Captures digital signals and supports protocol decoding via desktop software. 
  • GAO RFID Logic Analyzers 
    Deployed in IoT and embedded environments to decode communication protocols like SPI, I²C, UART. Widely used across industries for lowlevel signal capture and protocol verification. 
  • GAO RFID/BLE Readers & Gateways 
    Multiprotocol readers (LF, HF, UHF, BLE/NFC) provide traffic sources from RFID systems. Useful for protocol analysis of tag/reader interactions and data flows in asset tracking or BLE networks. 

Key Benefits

  • Full-stack protocol capture—from L1 to transaction layer—with precision timing and state analysis. 
  • Flexible deployment: field handheld Ethernet capture, desktop logic analysis, embedded RFID/IoT protocol decoding. 
  • Powerful software triggers, alerts, and filters provide actionable insights quickly. 
  • All components originate from GAO Tek Inc. or GAO RFID Inc., ensuring seamless integration and consistent support. 

Testing Architecture

  • Packet Capture & Ethernet-Level Analysis 
    Use the handheld LAN Network Analyzer at network endpoints to sniff live frames, decode TCP/IP, HTTP, FTP, SIP, etc., and trigger deep inspections via capture filters. 
  • Hardware Protocol Decoding 
    Connect GAO Tek logic analyzers (both portable and USB-based models) to embedded or device interfaces, capturing raw signal timing and protocol-level errors across buses and communication channels. 
  • Combined Network + IoT Diagnostics 
    Integrate GAO RFID readers/BLE gateways to simulate RFID/BLE transactions. Use logic analyzers in parallel to capture and correlate protocol events at both network and device levels. 
  • Real-Time Monitoring & Alerts 
    Protocol analyzer software includes filtering, transaction summaries, and trigger-based alerts for latency, retransmissions, malformed packets, or abnormal patterns. 
  • Post-Test Analysis & Reporting 
    Export captured packets, timing diagrams, and decoded sessions. Use software interfaces for historical review, regression testing, forensic investigations, or compliance auditing. 

Use Cases

  • VoIP & SIP Troubleshooting: Identify malformed SIP messages, jitter, or retransmission issues in unified communications. 
  • Embedded Device Protocol Verification: Debug UART/SPI/I²C communication to ensure firmwarehardware interactions adhere to spec. 
  • Asset Tracking Protocol Analysis: Monitor RFID/BLE interactions between tags and readers, and detect anomalies in data flows. 
  • Security & Anomaly Detection: Spot unauthorized packet patterns, unexpected protocol behavior, or rogue devices on network segments. 

Key Features & Functionalities

  • Deep Packet Inspection (DPI): Capture and analyze full packet payloads across network layers.
  • Protocol-Specific Decoding: Interpret behaviors of various protocols including TCP, UDP, HTTP, FTP, SIP, VoIP, and more.
  • Real-Time Traffic Monitoring: Continuously track flows for anomalies, congestion, or unauthorized activity.
  • Filter & Drill-Down Capabilities: Pinpoint issues using customizable filters, triggers, and time-based events.
  • Automated Alerts & Logging: Set thresholds for latency, retransmission, or dropped connections and trigger automated responses.
  • Historical Data Analysis: Archive sessions for retrospective review, auditing, or security investigations.

Case Study 1 – U.S.: Cybersecurity Oversight for a Mid-Atlantic Utility Company

A major utility firm in Virginia partnered with nettestfordatacenters to evaluate slow database syncs between redundant sites. Our Network Protocol Analysis revealed retransmission spikes and malformed packets caused by a misconfigured firewall rule. After tuning the firewall and adjusting MTU sizes, network sync times improved by 70%, ensuring faster load balancing and operational continuity.

Case Study 2 – U.S.: Network Segmentation Verification for a Financial Institution

A national credit union in Oregon needed to verify traffic segmentation between their internal and DMZ zones during a compliance audit. Using our protocol analysis tools, IT staff confirmed secure separation and detected a misrouted syslog feed. Quick remediation helped pass the audit with zero non-conformities and enhanced visibility into their security posture.

Case Study 3 – Canada: QoS Troubleshooting for a Montreal-Based Healthcare Network

A provincial health agency faced periodic disruptions in telehealth video conferencing. Using nettestfordatacenters protocol inspection tools, engineers uncovered RTP packet degradation due to competing FTP backup processes. By reclassifying the FTP flows and enforcing QoS priorities, the agency achieved stable, high-quality teleconferencing during critical patient consultations.
