The Configurable AD Convertor device driver is a AD Converter which is supported by RadiMation®.
Initialisation and Check[edit]
 Reset
|
The reset code that needs to be send to device. When left blank no command will be send. |
| Init
|
The command that is send to initialize the configured device. When left blank no command will be send. |
| Get Id
|
The command that is send to retrieve the ID of the device. This is used to check if the device is connected. A common used SCPI command is *IDN?. When left blank no command will be send. |
Channels[edit]
AD convertors can have multiple channels on which AD values could be read. For each AD channel, different commands can be set.
Trigger and Reading[edit]
| Trigger
|
A trigger command can be specified to request a measurement from the device. A common used SCPI is *TRG. When left blank no command will be send. |
| Read Back
|
Different devices return different messages with measurement values. The configurable AD converter only need the numeric value of the measurement message. There for, a regular expressions can be set in the Read Back.
A good regular expression for finding the first number in scientific notation in a text is: ([+-]?[0-9]*\.?[0-9]+([eE][+-]?[0-9]+)?) For more possibilities see the example section |
Minimum and maximum value[edit]
Minimum and maximum can be set to limit the measured value. And to calculate the measured value to a specific unit.
| Minimum value
|
The lowest value that can be measured with this device. The value must be the same as filled in the EUT window. |
| Maximum value
|
The highest value that can be measured with this device. The value must be the same as filled in the EUT window. |
