6. Device-specific (unclassified) commands
The commands in this section are specific to the BB3, and so are not included in the 1999.0 version of the SCPI standard. However, these commands are designed with the SCPI standard in mind, and they follow all of the command syntax rules defined by the standard.
6.1.1. APPLy
The APPLy command provides the most straightforward method to program the BB3 remotely.
|
Syntax |
APPLy {<channel>}, {<voltage>} [, <current>] APPLy? {<channel>} [, <query param>] |
|||
|
Description |
This command is a combination of the INSTrument:SELect (or INSTrument:NSELect), [SOURce[<n>]]:VOLTage and [SOURce[<n>]]:CURRent commands.
The APPLy changes the power module’s output to the newly programmed values only if the programmed values are valid within the presently selected power module operating range. An execution error will occur if the programmed values are not valid within the selected range. You can substitute MINimum, MAXimum, or DEFault in place of a specific value for the voltage and current parameters (see table below). |

Return |
APPLy? query the voltage/current of the specified channel. |

|
Usage example |
Set the voltage and current of CH1 to 35.5V and 0.5A respectively: APPL CH1,35.5,0.5 Query the voltage and current settings of the first channel: APPL? CH1 CH1:50V/3A, 35.500, 0.500 Query only current setting of the second channel: APPL? CH2, CURR 0.25 |
