HP / Agilent 11759C RF Channel Simulator, 50 MHz to 2700 MHz

The HP/Agilent 11759C RF Channel Simulator replicates complex signal propagation effects in wireless communication environments, enabling realistic laboratory testing of wireless devices and systems without extensive field trials. This instrument simulates fast and slow fading, time dispersion, Doppler shifts, and multipath conditions experienced by mobile users across RF bandwidths up to 6.0 MHz.

– Technical Specifications

• Frequency Range: 40 MHz to 2700 MHz
• RF Bandwidth (1 dB): Greater than 6.0 MHz
• Doppler Shift Range: ±425 Hz (equivalent to ±509 km/h at 900 MHz)
• Doppler Profiles: Classical, pure, flat, Gaussian + Rice
• Fading Statistics: Rayleigh and Rice
• Delay Intervals: Up to 186 µs with 1 ns resolution (1.48 ms available by special order)
• Path Attenuation: 0 to 50 dB in 0.1 dB steps
• Path Insertion Loss: Typically 24 dB ±3 dB
• Independent RF Channels: 2 of 3 paths each (Option 001 provides one channel of 6 paths)
• Processing: 12-bit
• LO Input Frequency Range: RF input frequency minus 6 MHz

– Key Features

• Simulates multipath fading with independent control of signal attenuation and delay per path
• Supports both Doppler and non-Doppler simulation modes for mobile and fixed scenarios
• AWGN injection capability for noise floor evaluation
• Flexible channel architecture: standard dual 3-path configuration with single 6-path option available

– Typical Applications

• Digital cellular radio testing under RF multipath conditions
• GSM, NADC, DCS1800, and PDC system validation
• CDMA system testing (with Option H30)
• Analog and digital wireless communication systems assessment

– Compatibility & Integration

Available options include 6-path channel expansion (Opt 001), rear-panel-only RF connectors (Opt 002), combined 6-path with rear connectors (Opt 003), and mechanical mounting kits (907, 908, 909). Rack mount flange kits and front panel handle assemblies facilitate laboratory and production environments.
