Keysight E3644A DC Power Supply

The Keysight E3644A DC Power Supply can be associated with the RS-232 interface by utilizing the 9-pin serial connector (DB-9) on the back board. The power supply is configured as a Data Terminal Equipment Device (DTE). For communications with the RS-232 interface, the power supply utilizes two handshake Lines: Data Terminal Ready (DTR, looking into pin 4) and Data Set Ready (DSR, for pin 6).

On the E3644A, it is possible to determinate the amount of times that the power supply has been calibrated. The power supply might have been adjusted in the recent past before it left the factory. When the user receives their power supply, it is possible to read the count to determine its initial value. The calibration count characteristic can be performed from the remote interface only.

The command syntax in this model demonstrates most commands (and a few parameters) as a mixture of upper-case and lower-case letters. The upper-case letters demonstrate the abbreviated spelling for the command. For shorter project lines, the user can send the abbreviated form. For finer project readability, the user can send the long form. In this model, a vertical bar (|) separates different parameter choices for a provided command string. This instrument has one range with a voltage of 0 to 8 V and a current of 8 A, while the second range is 0 to 20 V and 4 A.
