The Keysight/Agilent/HP 86603A RF Section Module is a plug-in component for 8660-series synthesized signal generator mainframes. It extends frequency coverage to 2600 MHz and delivers carrier generation with precise frequency resolution, low harmonic content, and selectable modulation modes including AM and optional phase modulation.
## Technical Specifications
• **Frequency Range:** 1 to 2600 MHz
• **Frequency Resolution:** 1 Hz (below 1300 MHz); 2 Hz (1300 MHz and above)
• **Harmonic Content:** Below −30 dBc (below 1300 MHz); Below −20 dBc (1300 MHz and above)
• **Signal-to-Phase Noise Ratio:** Greater than 45 dB (below 1300 MHz); Greater than 39 dB (1300 MHz and above)
• **AM Modulation Depth:** 0–90% (below 1300 MHz); 0–50% (1300 MHz and above)
• **Pulse Rise/Fall Time:** 50 ns
• **PM Maximum Peak Deviation:** 0–100 degrees (below 1300 MHz); 0–200 degrees (1300 MHz and above)
## Key Features
• Dual-range performance with frequency-dependent specifications optimized for lower and upper band operation
• Fine 1 Hz or 2 Hz frequency resolution for precise carrier tuning
• Low harmonic distortion suitable for sensitive RF measurements
• AM modulation with depth control across full frequency range
• Optional phase modulation capability via Option 002
• Fast pulse modulation with 50 ns transition time
## Compatibility & Integration
Designed for 8660A, 8660C, and 8660D mainframes. Operation with 8660A requires Option 003. Phase modulation (Option 002) integrates with HP 86634A and HP 86635A modulation sections. The HP 11661B Frequency Extension Module is required when pairing 86603A with 8660C mainframes in certain configurations.
**Product Status:** Obsolete.
