Initialisation and Check[edit]

ScreenElementDescription.svg Reset The reset code that needs to be send to device. When left blank no command will be send.
ScreenElementDescription.svg Init The command that is send to initialize the configured device. When left blank no command will be send.
ScreenElementDescription.svg 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.
ScreenElementDescription.svg Returned ID The identifier is used to check if the correct device driver is selected and the device is connected. Leaving this blank will skip the device check.
ScreenElementDescription.svg Deinit Specifies the command that is send when the device is no longer in use. Leaving this blank will keep the device in its last state after controlling it.


A checkmark can be enabled so all the commands will be waiting for completion. This is done by sending SCPI command *OPC?.


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]

ScreenElementDescription.svg 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.
ScreenElementDescription.svg Read Back Different devices return different messages with measurement values. The configurable AD convertor 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.

ScreenElementDescription.svg Minimum value The lowest value that can be measured with this device. The value must be the same as filled in the EUT window.
ScreenElementDescription.svg Maximum value The highest value that can be measured with this device. The value must be the same as filled in the EUT window.
