SYSTEM FUNCTION KEYS

NUMERIC ENTRY KEYS

Figure 6-1. Front Panel (Model 6626A shown)

Pressing the ENTER key will enter the values displayed for the function indicated, initiate that function, and return the display to the metering mode in which the measured output voltage and current for the selected output are displayed. Pressing the ENTER key without entering numbers will result in retention of the previous values and return to the metering mode. You can also return to the metering mode at anytime by pressing the RESET key.

The RANGE V/I key is used to display the voltage and current range settings. The key toggles; pressing it will display the range, pressing it again will put the display back to background metering. The range display shows the largest values of voltage and current that can be set for the ranges presently set.

The voltage step and current step (arrow keys) are used to change voltage & current settings and voltage & current ranges. There are 3 modes:

1.To use the step keys to immediately change the output settings, the background metering mode must be in affect.

2.To use the step keys to change the setting, the VSET or ISET key must be pressed first. The step keys can then be used to adjust the setting. Press the ENTER key to change the actual setting.

3.To use the step keys to change the voltage or current ranges first press the RANGE V/I key. The step keys change the range as long as the RANGE display is in effect.

Note

The step keys change the voltage or current by 1 LSB each time they are pressed. If the key is held down

 

more than 1 second, the automatic step mode goes into effect. The step rate will start to increase from the

 

initial value after about 3 seconds.

Setting Voltage and Voltage Range

The selected output’s voltage is programmed locally using the VSET key. For example, program the voltage to 5.25 volts by pressing:

The front panel display then indicates the actual output voltage and current for the selected output.

6629A, 6625A, 6626A, 6628A specifications

Agilent Technologies, a recognized leader in electronic test and measurement solutions, has developed a series of precision power supplies ideal for a variety of applications in both research and industry. The Agilent 6628A, 6626A, 6625A, and 6629A are part of the Agilent 6000 series and stand out due to their innovative technologies and robust functionalities.

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.
