The Fluke DSP-4000 is a digital cable analyzer engineered for certification, testing, and troubleshooting of LAN cabling infrastructure. Operating across a bandwidth of 350 MHz, it delivers precise characterization of copper twisted-pair and fiber optic cables while supporting TIA Categories 3, 4, 5, 5e, and 6 per TIA/EIA standards and ISO/IEC 11801 Class C and D specifications.
## Technical Specifications
• Bandwidth: 350 MHz
• Supported cable types: UTP, STP, ScTP, coaxial (10BASE5, 10BASE2, RG-58, RG-59, RG-8, RG-62 variants), and fiber optic (multimode and singlemode with optional accessories)
• Test parameters: Wire map, DC loop resistance, length, propagation delay, delay skew, characteristic impedance, NEXT, NEXT @ Remote, PSNEXT, PSNEXT @ Remote, return loss, return loss @ Remote, attenuation, ACR, ACR @ Remote, PSACR, ELFEXT, ELFEXT @ Remote, and power sum ELFEXT
## Key Features
• One-button diagnostics for instantaneous fault identification and corrective action guidance
• Patented bi-directional Time Domain Crosstalk (TDX) analyzer for crosstalk localization
• Enhanced High Definition Time Domain Crosstalk (HDTDX) and High Definition Time Domain Reflectometry (HDTDR) for pinpointing return loss and crosstalk sources
• Permanent Link Adapter for accurate link testing without false failures
• Channel testing capability with optional Channel Adapters
• Network traffic monitoring on 10BASE-T and 100BASE-TX
• Detects shorts, opens, and cabling anomalies
## Typical Applications
• LAN installation certification and acceptance testing
• Network troubleshooting and fault localization
• Preventive maintenance on copper and fiber infrastructure
• Cable plant auditing and compliance verification
## Compatibility & Integration
Certifies TIA/EIA-568B Category 3, 5e, and 6; TIA TSB-95 Category 5 (1000BASE-T); and ISO/IEC 11801-2000 Class C and D. Optional adapters enable IBM Type 1, 6, and 9 STP testing and multimode/singlemode fiber characterization.
