Sending a Remote Command

To send the power supply a remote command, combine your computer’s output statement with the GP-IB interface select code, the GP-IB device address, and finally, the power supply command. For example, to set the output voltage of output channel 1 to 2 volts, send:

Getting Data From The Supply

The supply is capable of measuring the values of its output parameters in response to queries. In this example, the query asks the supply to measure the output voltage at output 1.

When you send a query from remote, the supply does not display the response as it did when you executed the command from the front panel. Instead, it holds the response in an output buffer. The output buffer is a register that holds information until it is read by the computer or is replaced with new information.

Note

On an Agilent Series 200/300 Computer, the A variable must be declared before you do the following

 

steps. Refer to your computer’s operating manual for more information.

 

 

Use your computer’s enter statement to get the response from the output buffer. For example, execute:

ENTER 705; A

Followed by:

DISP A

The ENTER statement enters whatever is in the supply’s output buffer into the computer’s A variable. The DISP statement displays the A variable’s contents on the computer’s display.

Often Used Commands

The command set contains over sixty commands that allow you to program the power supply in a variety of applications. Within this command set, however, is a small subset of commands that are all you need for most applications. These commands are: VRSET, IRSET, VSET, ISET, VOUT?, IOUT?, OUT, OVSET, and OCP.

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.
