The Agilent/Keysight 8672S Synthesized Signal Generator is a high-performance RF and microwave test instrument that combines the 8672A Synthesized Signal Generator with the 86720A Frequency Extension Unit. This integrated system delivers precision signal generation across 10 MHz to 18.0 GHz with flexible modulation, extensive programmability, and exceptional output control.
Technical Specifications
Frequency Coverage: 10 MHz to 18.0 GHz
Output Power:
• 0.01–2.0 GHz: +13 dBm to −120 dBm
• 2.0–18.0 GHz: +2 dBm (or +7 dBm with Option 008) to −120 dBm
• Level flatness degrades ±0.25 dB relative to the 8672A
Frequency Tuning Resolution: Selectable via front panel—100 MHz, 1 MHz, 10 kHz, or 1 kHz. At 1 kHz resolution: 1 kHz (2.0–6.2 GHz), 2 kHz (6.2–12.4 GHz), 3 kHz (12.4–18.599997 GHz)
Modulation Capability: AM, FM, and pulse modulation. Internal pulse modulator delivers high-quality pulse signals across the full 10 MHz to 18 GHz range with >80 dB ON/OFF ratio.
AM Depth: Selectable ranges of 30% and 100%, linearly variable with external voltage
FM Deviation: Five selectable ranges (0.03, 0.1, 0.3, 1.3, and 10 MHz), linearly variable with external voltage
Frequency Stability: Locked to internal 10 MHz reference or external 5/10 MHz oscillator
Leveling Control: Internal ALC for exceptionally flat output power; external leveling supported via diode detector or power meter
Phase-Locked Outputs: 10 MHz and 100 MHz available on rear panel
– Key Features
• Full HP-IB programmability for all functions except line switches and meter mode
• Front panel meter displays output level, AM depth, or FM peak deviation
• Low spurious signals and phase noise
• Single 9-inch high package: 222 mm (H) × 425 mm (W) × 620 mm (D)
– Typical Applications
Demanding RF and microwave testing, component characterization, and subsystem validation across L-, S-, C-, X-, and Ku-band frequencies.
– Compatibility & Integration
Existing HP 8672A generators can be retrofitted to 8672S configuration using the 86720A Frequency Extension Unit and either an 11731A or 11732A Frequency Extension Retrofit Kit.
