In the development, validation, and repair of portable electronic devices, accurately reproducing the real behavior of a battery is essential. The Agilent 66309D is designed specifically for this purpose, allowing you not only to power the device under test but also to simulate the battery’s internal impedance and analyze its dynamic current drain.
This type of instrumentation is key in R&D, manufacturing, and service environments, where characterizing energy consumption and detecting faults depend on realistic electrical conditions.
Realistic battery emulation
Unlike a conventional DC source, the 66309D can simulate the internal behavior of a battery, including its internal resistance. This makes it possible to recreate real operating scenarios, such as different states of charge or battery types.
This capability is especially useful for:
- Evaluating battery life and energy consumption
- Detecting intermittent faults in mobile devices
- Validating designs under real power supply conditions
- Simulating battery degradation or variations
Accurate emulation is essential when the goal is to replicate device behavior under real-world use, beyond simply providing a stable supply.
Dual-output configuration for complete testing
The 66309D features dual outputs, allowing the main battery and the device charger to be simulated simultaneously.
This enables configurations such as:
- One output connected in place of the battery (sinking or sourcing current)
- A second output powering the charger input
This allows more complete testing, including charging, discharging, and simultaneous operation scenarios, replicating real conditions of use.
Dynamic current drain measurement
The unit integrates an advanced measurement system that analyzes current consumption over time at high resolution. Its Battery Drain Analyzer makes it easy to capture transient events and consumption patterns, which is key for wireless devices.
Its notable capabilities include:
- Accurate measurement of dynamic current drain
- Event recording with a buffer of up to 4096 points
- Sampling intervals from microseconds to long periods
- Identification of consumption peaks and anomalous behavior
This makes it possible to optimize power designs and detect problems that are not visible in average measurements.
Superior performance in high-speed testing
The 66309D offers significant improvements over traditional DC sources, including:
- Up to 20 to 30 times faster test speed
- Excellent transient response (<35 µs)
- Low noise and ripple (down to 1 mV RMS)
- Stability even with long cables (up to 6 meters)
These characteristics maintain accuracy under real test conditions, avoiding measurement distortion.
