Hewlett Packard 8620C Sweep Oscillator w/ 86290A RF Plug-In (2–18 GHz) – Microwave / Radar Test System

Offered here is a Hewlett Packard 8620C Sweep Oscillator system paired with the desirable 86290A RF plug-in, covering an impressive 2.0–18.0 GHz frequency range.

This is a serious piece of Cold War–era electronic test equipment, used in radar development, microwave communications, and advanced RF system testing.

🔍 System Includes:

• HP 8620C Sweep Oscillator Mainframe
• HP 86290A RF Plug-In
• Frequency Coverage: 2.0–18.0 GHz
• Modular design allows for multiple band plug-ins (this is one of the higher-frequency configurations)

📦 Condition:

• Untested – we have not powered or calibrated this unit
• Clean, well-preserved cosmetic condition
• Stored properly and kept dry
• All knobs, switches, and connectors appear intact

Being sold as:

• Collector display piece
• Restoration project
• Or for use by a knowledgeable technician

📡 Historical & Technical Significance:

The HP 8620 series was widely used in:

• Military radar and microwave systems
• Telecommunications development
• Aerospace and defense electronics
• University and laboratory environments

The included 86290A plug-in extends this unit into the microwave spectrum (up to 18 GHz)—making it far more desirable than lower-band units.

💡 Why This One Stands Out:

• Complete system with RF plug-in (not just mainframe)
• High-frequency coverage (2–18 GHz)
• Classic HP modular lab equipment design
• Strong crossover appeal: radar collectors + electronics enthusiasts
