Coupling Decoupling Network for 50 ohm Cable
- ▸ 50 Ω coaxial CDN/ISN, 150 kHz–230 MHz — dual-purpose network for IEC 61000-4-6 conducted immunity testing and CISPR 22 / 32 conducted emissions testing on 50 Ω coaxial signal/data cables.
- ▸ 50 Ω BNC EUT and AE ports plus separate 50 Ω BNC RF injection port — impedance-matched coupling preserves signal integrity through the test path.
- ▸ 1 A max current, 310 VAC / 440 VDC voltage rating — supports DC-bias and signal-line voltages found on RF coax cables in instrumentation and communications systems.
- ▸ RF instrumentation port qualification — spectrum analyzers, signal generators, network analyzers, and other 50 Ω instrument I/O ports requiring CISPR 32 emissions and IEC 61000-4-6 immunity work.
- ▸ 50 Ω communications equipment — two-way radios, base-station electronics, RF modems, and microwave-link interface ports on 50 Ω coax.
- ▸ Industrial sensor and instrumentation cables — vibration analyzers, ultrasonic equipment, and SCADA RF links using 50 Ω coaxial connections.
- ▸ Aerospace and military COTS equipment with 50 Ω ports — commercial-off-the-shelf RF subsystems integrated into defense/avionics platforms requiring DO-160 or MIL-STD-461 supporting work.
- ▸ NIST-traceable individual calibration with three-year warranty — ISO/IEC 17025 accredited calibration optional; ADA-515-X 150 Ω / 50 Ω adapters available separately for IEC 61000-4-6 level setting; dual CDN/ISN function consolidates two test setups into one purchase.
CDN-C50E Features
- ▸ Screened-line CDN for 50 Ω coaxial — injects common-mode disturbance into the cable shield per IEC 61000-4-6 for conducted RF immunity testing
- ▸ 50 Ω BNC (female), EUT & AE EUT and AE connections for direct, in-line cable insertion
- ▸ Frequency range 150 kHz to 230 MHz — full IEC 61000-4-6 standard band including the extended-band test region up to 230 MHz
- ▸ 1 A maximum continuous current at 310 VAC / 440 VDC for power-over-data and bus-powered devices
- ▸ Voltage division factor: 9.5 dB — well-defined coupling per IEC 61000-4-6 for accurate test-level setting
- ▸ ≥ 50 dB EUT/AE isolation protects auxiliary equipment from the injected RF disturbance
- ▸ 50 Ω BNC (female) RF injection port — direct mate with immunity-test power amplifier through standard 50 Ω coax
- ▸ 40 Vrms maximum RF input — supports IEC 61000-4-6 test levels of 1, 3, and 10 Vrms with margin
- ▸ Dual-use as ISN for emissions testing — also usable as Impedance Stabilization Network for conducted emissions per CISPR 22 / CISPR 32, eliminating the need for two separate networks
- ▸ Typical use: 50 Ω coax RF/data ports (instrumentation, RF communications)
- ▸ NIST-traceable individual calibration with ISO/IEC 17025 accredited calibration available on request
- ▸ Compatible with ADA-515-X 150 Ω / 50 Ω calibration adapters for IEC 61000-4-6 test-level setting
- ▸ Three-year warranty — covers manufacturing and workmanship defects
