CDN for USB Type B
- ▸ USB Type-B 2.0 CDN, 150 kHz–230 MHz — injects common-mode RF disturbance into USB cables on the device (Type-B) side per IEC 61000-4-6.
- ▸ USB Type-B EUT-side connector and Type-A AE-side connector — orientation matches the typical EUT-as-device configuration with auxiliary Type-A host on the AE side; complementary to the CDN-USB-AE.
- ▸ 1 A max current at 30 VAC / 30 VDC, ≥ 50 dB EUT/AE isolation — supports bus-powered Type-B devices; isolation prevents AE host equipment from being stressed during testing.
- ▸ Printers, scanners, and peripheral devices — office printers, document scanners, label printers, and other peripherals using Type-B USB connections requiring IEC 61000-4-6 testing.
- ▸ External storage and external optical drives — external hard drives, USB CD/DVD drives, and Type-B-equipped storage devices requiring conducted immunity qualification.
- ▸ Industrial USB devices — barcode scanners, RFID readers, programmable instruments, and field-service tools with Type-B ports.
- ▸ Audio interfaces and instrumentation peripherals — pro audio interfaces, USB DAQ modules, and laboratory peripherals with Type-B USB connections.
- ▸ 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; pair with CDN-USB-AE for complete USB host/device test capability.
CDN-USB-BE Features
- ▸ Screened-line CDN for USB Type B (USB 2.0) — injects common-mode disturbance into the cable shield per IEC 61000-4-6 for conducted RF immunity testing
- ▸ EUT: USB Type B; AE: USB Type A 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 30 VAC / 30 VDC for power-over-data and bus-powered devices
- ▸ Voltage division factor: 9.5 dB +2 / −1 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
- ▸ Typical use: USB Type-B device-side immunity test setups
- ▸ 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
