## Key Features
• 1 kHz frequency resolution enables fine-grain tuning for precision characterization
• User flatness correction accommodates operational modes (CW, step, list, manual, and ramp sweep)
• Multiple sweep modes support diverse test scenarios from transient response to frequency-dependent behavior
• Output level specifications maintain accuracy across 15 °C to 35 °C operating window
• Modulation options compatible with Agilent 8360B series; pulse modulation available above 400 MHz
## Typical Applications
• Component and subsystem characterization in RF/microwave design
• Frequency response and gain flatness measurement
• Stimulus/response testing for amplifiers and filters
• Aerospace and defense signal simulation
• Communications system validation
## Compatibility & Integration
GPIB trigger support enables automated test sequencing. AC power supply requires proper line voltage selector and grounding via three-prong cord. Cabinet installation demands unrestricted convection; ambient temperature must remain 4 °C below instrument maximum for every 100 watts cabinet dissipation.
