The HP/Agilent 83540A is an RF plug-in module for the 8350A/B sweep oscillator mainframe, delivering signal generation across the 2.0 to 8.4 GHz band. This unit expands mainframe capability for RF and microwave component characterization, network analyzer integration, and broadband system testing. The 83540A outputs leveled power exceeding 16 dBm and provides wide dynamic range control from +20 dBm to −69 dBm with 0.1 dB displayed resolution when equipped with the optional 70 dB step attenuator (Option 002).
## Technical Specifications
• Frequency range: 2.0 GHz to 8.4 GHz
• Maximum leveled power: >16 dBm
• Output power control: +20 dBm to −69 dBm (with step attenuator)
• Output power resolution (displayed): 0.1 dB
• Power consumption: Approximately 270 VA (8350B mainframe with RF unit)
• Mainframe power requirement: 100, 120, 220, or 240 VAC ±10%, 50 to 60 Hz (Option 400: 60 to 400 Hz)
## Key Features
• Step attenuator option (Option 002) extends dynamic range by 70 dB
• Rear panel RF output connector available (Option 004)
• Compact integration with 8350A/B mainframe: 425 mm × 133.3 mm × 422 mm
• 0.1 dB power level granularity supports precision characterization
## Typical Applications
• Component and subsystem characterization in the S, C, and X bands
• Network analyzer source for scalar and vector measurements
• RF subsystem testing requiring stable, leveled signal sources
• Frequency-selective gain and phase measurement
## Compatibility & Integration
The 83540A integrates directly into HP/Agilent 8350A and 8350B mainframes. System configurations support HP 8756 and 8757 series network analyzers, the HP 8510 vector network analyzer, and the HP 8757A scalar network analyzer when used with the 8350B mainframe.
