Frequently asked questions
A precision power supply goes beyond simply delivering voltage and current. It offers high accuracy, stability, and built-in measurement capabilities, making it a superior choice for demanding test applications.
1. Higher accuracy
- A precision power supply provides high-resolution voltage and current control, often with millivolt (mV) and microamp (µA) precision, ensuring minimal fluctuations.
- Regular power supplies may have larger tolerances and higher noise levels, which can impact sensitive measurements.
2. Built-in measurement capabilities
- Precision power supplies integrate voltmeters and ammeters, eliminating the need for external multimeters or current probes.
- This feature simplifies test setups and improves measurement accuracy by reducing additional cabling errors and noise.
3. Low noise & high stability
- Designed for low-ripple, low-noise performance, precision power supplies prevent unwanted signal interference, making them ideal for semiconductor testing, sensor calibration, and RF applications.
- Regular power supplies, especially switching models, often introduce more noise and ripple, which can affect test results.
4. Advanced features for test & automation
- Many precision power supplies offer programmable output sequences, data logging, and remote sensing, enabling precise control over test conditions.
- Regular power supplies typically provide basic voltage and current control but lack advanced automation and monitoring features.
5. Ideal for R&D and critical testing
- You can use precision power supplies in applications where high accuracy is essential, such as battery characterization, medical device testing, and aerospace electronics.
- Regular power supplies are more suited for general-purpose power delivery, such as bench testing and simple circuit validation.
A low-noise output ensures that the source signals are stable and precise, which is critical when measuring small currents or voltages, such as in sensitive semiconductor, nano-material tests. and sensor calibration where even a small amount of noise can affect results.
A built-in AWG in a DC power supply provides the ability to generate complex, time-varying output signals, beyond standard fixed or ramped voltage and current levels. This capability is highly beneficial for testing devices that operate under dynamic power conditions, such as battery-powered electronics, automotive components, or power converters.
With an integrated AWG, you can create and output custom voltage or current waveforms that simulate real-world operating scenarios, like voltage dips, load transients, or periodic power cycles, without needing external signal generators or additional equipment. This not only saves space and cost but also simplifies test setup and improves synchronization between the waveform and output behavior.
