Output response time: Beginning at the time the power supply has finished processing a VSET command (change output voltage), the maximum time for the output voltage to settle to within a settling band about the final value from any specified operating point. This value must be added to the command processing time to obtain total programming time (see Figure 1-3). Time constant is the maximum time required for the voltage to reach 63% of its final value.

Figure 1-3. Output Response Characteristics

Temperature coefficient: Maximum change in the regulated output parameter per °C change in ambient temperature after a 30 minute warmup. Expressed as a percentage plus a constant per degrees C. (Plus a constant for readback temperature coefficient).

Long Term Drift: Maximum change of regulated output voltage or current during an 8-hour period following a 30 minute warmup, with all influence and control quantities maintained constant. Expressed as a percentage of the setting plus a constant.

Short Term Drift: Maximum change of regulated output voltage or current within 30 minutes after a line and/or load change. Expressed as a percentage of the setting plus a constant.

Output Noise (PARD): PARD replaces the former term ripple and noise. PARD is the periodic and random deviation of dc output voltage or current from its average value, over a specified bandwidth and with all influence and control quantities maintained constant.

Programming resolution: Average programming step size.

Current Sinking (- Current): Each output can sink as well as source current. The sinking capability is not programmable and depends upon the output voltage. The current sinking capability is described in greater detail in

Chapter 4.

The Agilent 6628A is a triple-output power supply, featuring two 0 to 20 V outputs capable of delivering up to 3 A each, along with a 5 V output that can supply 5 A. This combination is perfect for supplying power to devices that require multiple supply voltages simultaneously, making it an excellent choice for testing and development purposes.

The Agilent 6626A, on the other hand, offers dual output capabilities with higher specifications. Each of its outputs can be adjusted from 0 to 25 V and delivers up to 3 A, providing enhanced flexibility for designers and engineers working with various devices. Additionally, the 6626A's compact size and lightweight design make it easy to integrate into test setups without occupying excessive space.

For applications that require comprehensive monitoring, the Agilent 6625A provides a unique solution with its built-in digital voltmeter (DVM). This power supply comes with two 0 to 25 V outputs, both capable of 3 A. The integrated DVM allows real-time measurement and displays voltage and current values, ensuring accurate readings during experimentation and testing.

Lastly, the Agilent 6629A is designed for high-performance applications, providing up to four outputs, including two adjustable outputs that can be set between 0 to 35 V and deliver 5 A each. This model is particularly suited for environments where multiple devices need to be powered simultaneously with varying voltage requirements.

All four models come equipped with key features including ease of programming, precision regulation, and superior load transient response. They employ advanced technologies like low-noise operation and excellent line regulation, ensuring stable performance under varying load conditions. Additionally, safety features such as overvoltage protection, current limiting, and rapid recovery from overloads guarantee reliable operation.

In summary, Agilent's 6628A, 6626A, 6625A, and 6629A power supplies provide versatile, precise, and reliable solutions for all electronic testing needs. Their characteristics and dedicated functionalities make them indispensable tools for engineers, researchers, and developers across numerous fields. Whether it's for prototyping, testing, or production, these power supplies deliver the quality and performance that professionals expect from Agilent Technologies.
