It can be used to control other measurement equipment, for which no RadiMation device driver is available yet. The Configurable Turn Table allows to manual create a device driver to controll a Turn Table. Where the device then can be used in RadiMation. The Turn Table can thus be used for tests.

== Communication ==
Communication configuration can be done using the regular communication tab.
Depending on the connection that is used, select the correct {{ScreenElement|Communication Stream}}, and configure the parameters correspondingly.

== Initialisation and Check ==
{{ScreenElementDescriptionStart}}
{{ScreenElementDescription|Reset|The reset code that needs to be send to device. When left blank, no command will be send.}}
{{ScreenElementDescription|Init|The command that is send to initialize the configured device. When left blank no command will be send.}}
{{ScreenElementDescription|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 commonly used [[SCPI]] command is: *IDN?. When left blank, no command will be send.}}
{{ScreenElementDescription|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|Deinit|Specifies the command that is send when the device is no longer controlled. This can for example be used to put the measurement device is an intrinsic safe state. Leaving this blank, will keep the device in its last state after controlling it.}}
{{ScreenElementDescription|Wait for Completion after sending command|The checkmark can be enabled so {{RadiMation}} will wait for all the commands to complete, before it continues. This is done by sending [[SCPI]] command *OPC? to the device.}}
{{ScreenElementDescriptionEnd}}
 
== Channels ==
AD convertors can have multiple channels on which AD values could be read. The [[Configurable AD Convertor]] device driver is able to retrieve up to 40 measurement values from the measurement device.
For each AD channel, individual commands can be set, specific for the values that should be retrieved.
 
==== Trigger and Reading ====
{{ScreenElementDescriptionStart}}
{{ScreenElementDescription|Trigger|A trigger command can be specified to request a measurement from the device. A commonly used [[SCPI]] command is: *TRG. When left blank, no command will be send.}}
 
{{ScreenElementDescription|Read Back|Different measurement devices will return different messages that contain the measurement value. The configurable AD convertor only needs the numeric value of the measurement device response. The text that is specified in the {{ScreenElement|Read Back}} box, is used as a [[regular expressions]] to determine the returned value.
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.
}}
{{ScreenElementDescription|Validate Expression|Shows a window where the expected output of the measurement device and a regular expression can be typed. The result of the interpretion will then automatically be shown. This window can be used to test the regular expression, to determine if the expected response results in the desired value.}}
{{ScreenElementDescriptionEnd}}
 
==== Minimum and maximum value ====
The minimum and maximum must be set to calculate the raw AD convertor value to a digital value with a specific type.
 
{{ScreenElementDescriptionStart}}
{{ScreenElementDescription|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|Maximum value|The highest value that can be measured with this device. The value must be the same as filled in the [[EUT]] window.}}
{{ScreenElementDescriptionEnd}}
 
With minimum set to 0 and maximum set to 1, the raw value won't be converted, but instead directly used as it is included in the response.

The [[regular expression]] can always be tested trough the {{ScreenElement|Validate Expression}} function.
