Functions
Dynamically stabilizes an RF source's output power to a precise, constant level across its operational frequency range. It integrates power sensing and feedback control, often via automatic level control (ALC) mechanisms, to adjust source output or external attenuation, ensuring optimal 50 Ohm impedance matching for consistent signal delivery.
Platforms
Precision RF calibration laboratory systems requiring 50 ohm impedance level calibration; designed to operate as a high-accuracy signal source with an integrated 50 ohm leveling head delivering low-loss, low-noise, and low-mismatch signals directly to units under test (UUTs) typically including spectrum analyzers, RF level meters, and receivers. Interfaces via a rugged single RF output connection in 50 ohm systems; reduces or eliminates the need for separate power meters, step attenuators, and external sensors. Supports internal AM, FM, PM modulation for modulation analyzer and spectrum analyzer sweep testing, compatible with automated or manual calibration environments.
Applications
Precision leveling of RF signals at 50 Ohms; calibration of RF power meters and signal generators; automated test systems requiring accurate power level control; metrology applications needing traceable RF power standards; characterization of RF components and systems.
Accessories
50-ohm BNC male connector for RF interface, power supply cable with mini-DIN 6-pin connector, USB Type-B port for PC connection, calibration and adjustment tool for maintenance, localized power adapter for international compatibility.
Interfaces
GPIB (IEEE-488), BNC (50 Ohm) for RF output, USB-B for control, 25-pin D-sub for external triggering, calibration, and reference input.
Specifications
The 9640A-50 performs precision RF signal leveling from 100 kHz to 2.5 GHz with 50-ohm impedance. It employs a diode detector and internal feedback loop for maintaining a constant output level. The unit interfaces with a compatible signal generator via a dedicated leveling input and output port and is primarily used in RF test setups for calibration and measurement applications, ensuring accurate signal generation and control.
