The HP/Agilent 83545A is an RF plug-in module for the 8350A/B sweep oscillator mainframe that extends signal generation capability into the 5.9 GHz to 12.4 GHz microwave band. It delivers internally leveled output with power variations under 0.6 dB, supporting scalar network analysis, component testing, and local oscillator applications requiring precision RF signal generation across the X-band and lower Ku-band spectrum.
## Technical Specifications
**Frequency Range:** 5.9 GHz to 12.4 GHz
**Output Power:** Typically +2 dBm to +17 dBm; internally leveled to at least +17 dBm with power variations less than 0.6 dB. Power resolution: 0.1 dB displayed.
**Frequency Accuracy:** ±20 MHz
**Sweep:** Minimum sweep time 10 ms. Power sweep function available for response measurements.
**Modulation:** Internal AM selectable to 27.8 kHz or 1 kHz. External AM/FM capabilities deferred to RF unit specifications.
**Programmability:** Complete HP-IB control of all front panel functions (except AC line power switch) on 8350B mainframe.
**Signal Performance:** Slope compensation provided.
## Key Features
• High output power capability with internal leveling for repeatable measurements
• Fast 10 ms minimum sweep time for efficient signal characterization
• Dual AM modulation frequencies for flexible test scenarios
• Full HP-IB remote programming on compatible mainframes
• Laboratory-verified performance extending to +22 dBm
## Typical Applications
• Scalar network analysis across X and lower Ku bands
• Microwave component characterization and testing
• Local oscillator for high-frequency signal down-conversion
• RF system validation and bench measurements
## Compatibility & Integration
Requires HP/Agilent 8350A or 8350B sweep oscillator mainframe. The 83545A operates as a plug-in module within these platforms. Optional 002 step attenuator (70 dB) and 004 rear panel RF output connector available. An HP 11869A adapter enables interface with HP 86200 series plug-ins.
